Automated external defibrillator AED: Overview, Uses and Top Manufacturer Company

Introduction

An Automated external defibrillator AED is a portable medical device designed to analyze a person’s heart rhythm and, when appropriate, deliver an electrical shock (defibrillation) to help restore an organized rhythm during suspected cardiac arrest. It is built to be used quickly, often by responders who are not expert ECG (electrocardiogram) interpreters, because the device provides prompts and automated rhythm analysis.

In hospitals and clinics, the Automated external defibrillator AED sits at the intersection of clinical urgency and operational readiness. Clinically, seconds matter during sudden collapse; operationally, an AED is only useful if it is present, charged, in-date, and staff are trained. This makes it both a frontline resuscitation tool and a piece of hospital equipment that demands strong governance (placement, checks, training, maintenance, and post-event review).

What is Automated external defibrillator AED and why do we use it?

Clear definition and purpose

An Automated external defibrillator AED is a battery-powered clinical device that:

• Uses adhesive electrode pads placed on the chest to sense an ECG rhythm
• Applies an internal algorithm to determine whether a rhythm may be “shockable”
• Prompts the user through steps such as “analyzing,” “start CPR,” and “shock advised/no shock advised”
• Delivers a defibrillation shock (semi-automatic models require pressing a shock button; fully automatic models may deliver without a button press), depending on design and local configuration

The purpose is to enable early defibrillation when it is potentially indicated, while reducing reliance on manual rhythm interpretation in time-critical environments.

Where this medical equipment is commonly used

Automated external defibrillator AED deployment varies by health system design, but common settings include:

• Hospitals: wards, outpatient departments, procedure areas, dialysis units, imaging waiting areas, entrances, cafeterias, and sometimes on code carts
• Clinics and ambulatory centers: urgent care, specialty clinics, dental clinics (varies by jurisdiction and scope)
• Emergency medical services (EMS): first responder bags and ambulances
• Public access: airports, malls, schools, gyms, transport hubs, workplaces (depending on policy and regional adoption)

For administrators, AEDs are often categorized as high-impact, low-frequency hospital equipment: rarely used by any one unit, but critical when needed.

Key benefits in patient care and workflow

Benefits typically cited in operational planning and resuscitation training include:

• Speed to first shock (when appropriate): AEDs are designed for rapid deployment and clear prompts
• Standardized workflow: voice/visual instructions can reduce team variability, especially in non-ICU areas
• Lower cognitive load: rhythm analysis is automated, helping teams focus on compressions, airway, and calling for help
• Event documentation: many units record rhythm snippets, timestamps, and shock counts for post-event review (features vary by manufacturer)
• Training alignment: AED workflows map closely to basic life support (BLS) algorithms taught in simulation and skills labs

How it functions (plain-language mechanism)

At a high level, an AED does three jobs:

1. Senses: The pads pick up the heart’s electrical signal and assess pad contact (impedance).
2. Decides: The device runs an algorithm to determine whether a shockable rhythm is present. AEDs generally target rhythms like ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT); exact detection logic and labeling vary by manufacturer.
3. Delivers: If criteria are met, the unit charges an internal capacitor and delivers an electrical shock through the pads. Many contemporary AEDs use biphasic waveforms, but this varies by manufacturer and model.

Most AEDs also guide the user through cardiopulmonary resuscitation (CPR) cycles, sometimes with a metronome or CPR feedback technology.

How medical students and trainees encounter it

Learners typically meet the Automated external defibrillator AED in:

• BLS courses: pad placement, “clear” commands, and compressions-first workflow
• ACLS (advanced cardiovascular life support) exposure: understanding shockable vs non-shockable rhythms conceptually (while AED use remains simplified)
• Simulation (“code blue”) training: team roles, closed-loop communication, and safe defibrillation behaviors
• Clinical rotations: ward emergency responses, outpatient safety drills, and equipment checks

For trainees, the educational value is not only device mechanics—it is learning how a time-critical system works: recognizing deterioration, activating help, using equipment correctly, and documenting actions.

When should I use Automated external defibrillator AED (and when should I not)?

Appropriate use cases (general)

In many resuscitation protocols, an Automated external defibrillator AED is used when:

• A person is unresponsive and not breathing normally (or has agonal breathing), and the responder suspects cardiac arrest
• A collapse is witnessed or suspected and an AED is available quickly
• A responder team is awaiting higher-level support (e.g., code team, EMS) and needs a structured defibrillation pathway

The AED is designed to be used rapidly while CPR is started and help is activated, consistent with local training.

Where an AED may not be suitable (general concepts)

Situations where use may be inappropriate or requires strict protocol alignment include:

• The patient is responsive or has signs of life inconsistent with cardiac arrest (AEDs are intended for arrest scenarios in most protocols)
• A valid do-not-resuscitate (DNR) / DNACPR order or local policy limits resuscitation attempts (processes vary by jurisdiction and facility)
• You are in an environment unsafe for electricity (e.g., explosive atmosphere). This is a safety issue rather than a clinical contraindication.
• Rhythms that are typically non-shockable (e.g., asystole or pulseless electrical activity) — AEDs usually will not advise a shock, but teams should follow clinical protocols rather than “try shocks anyway.”

Clinical judgment and local governance matter. For example, pediatrics, hypothermia, drowning, trauma, and special populations have protocol nuances; the AED is still a tool within a broader resuscitation system.

Safety cautions and common contraindication themes (non-exhaustive)

These are practical, safety-focused cautions often included in training and IFUs; exact instructions vary by manufacturer:

• Water and moisture: Dry the chest and avoid delivering a shock while the patient is in standing water; consider environmental safety first.
• Oxygen-rich environments: Avoid shocking in a way that could ignite a concentrated oxygen flow near the chest; follow facility policy on oxygen management during defibrillation.
• Medication patches: Some transdermal patches may interfere with pad adhesion or concentrate current; follow local protocol and IFU guidance.
• Implanted devices: Pacemakers or implantable cardioverter-defibrillators (ICDs) can create a visible/palpable “bump.” Pad placement may need adjustment to avoid placing a pad directly over an implant site; follow training and IFU.
• Chest hair and poor adhesion: Excess hair, sweat, or lotions can reduce pad contact; many kits include a razor and towel for this reason.
• Small body size/pediatrics: Pediatric pads or energy attenuation may be required; availability and labeling vary by manufacturer.
• Motion and vibration: Movement can interfere with rhythm analysis; many AEDs require a “hands off” moment for accurate sensing.
• Electromagnetic interference: Certain environments (some procedure rooms, strong RF sources) may affect readings; this is context dependent.

Emphasize supervision, protocols, and system readiness

For trainees, a core professional habit is to think in three layers:

• Protocol layer: What does the facility’s resuscitation policy require right now?
• Device layer: Is this specific Automated external defibrillator AED ready, compatible (adult vs pediatric), and functioning?
• Team layer: Who is leading, who is compressing, who is managing the airway, who is documenting, and who is operating the AED?

Even with an automated device, resuscitation is a team process and should be performed under appropriate supervision based on role and scope.

What do I need before starting?

Required setup, environment, and accessories

A typical Automated external defibrillator AED “ready state” includes:

• AED unit with battery installed (or integrated battery) and a visible readiness indicator (varies by manufacturer)
• Adult defibrillation pads (sealed, in date)
• Pediatric pads or pediatric mode key/attenuator if your service covers children (varies by manufacturer and policy)
• Basic prep items often stocked with the AED: gloves, scissors, a towel/gauze, and a razor
• A safe working area with enough space to expose the chest and perform CPR
• A plan to call for help (code button/phone number/radio/EMS), consistent with local escalation pathways

In hospitals, AEDs may be mounted in cabinets, placed on trolleys, carried by response teams, or integrated into emergency carts. Placement strategy should match your facility’s response-time goals and staffing model.

Training and competency expectations

Because the AED is a medical device used in life-threatening emergencies, organizations commonly require:

• Initial training (often aligned to BLS) with hands-on pad placement and “clear” behaviors
• Role-based competency (e.g., clinical staff vs security vs reception staff in outpatient areas)
• Refresher training and mock drills to reduce skill decay
• Model-specific familiarization, especially if your organization uses multiple brands or generations

For biomedical engineers and operations leaders, training is also about workflow consistency: the same steps, the same language, and clear expectations for who brings the device, who applies pads, and who documents.

Pre-use checks and documentation (readiness culture)

Many facilities adopt a simple, auditable check process. Common elements include:

• Visual check of status indicator (if present)
• Confirmation of pad package integrity and expiry date
• Battery status check (indicator or display; varies by manufacturer)
• Inspection of cables/connectors for damage
• Cleanliness of the case and user interface
• Confirmation that spare consumables (pads/battery) are available per policy

Documentation approaches vary:

• Paper log on the unit or in the area
• Digital asset management systems
• Connected AED platforms (where available and approved) that report readiness remotely

The operational goal is not paperwork; it is reducing the chance of discovering an expired pad or depleted battery during an emergency.

Operational prerequisites: commissioning, maintenance, consumables, and policies

From a hospital operations lens, AED success depends on the “backstage” work:

• Commissioning: asset tag, location assignment, acceptance checks, and baseline functional tests per manufacturer and facility engineering policy
• Preventive maintenance: schedules and test methods vary by manufacturer; many AEDs perform automated self-tests, but facilities may still require periodic verification
• Consumables management: electrode pads and batteries are time-sensitive; establish reorder points and a rotation strategy
• Post-event workflow: immediate restocking, data handling (if the unit stores event information), and device cleaning
• Governance: clear policy on who can use the AED, where it must be stored, how quickly it must be retrieved, and escalation triggers

Roles and responsibilities (who does what)

A practical division of responsibilities looks like this (exact models vary by facility):

• Clinicians and first responders: retrieve the AED, apply pads, follow prompts, coordinate CPR, and document actions per code documentation practices
• Unit/department leadership: ensure staff competency, local drills, and compliance with daily/shift checks
• Biomedical engineering/clinical engineering: acceptance testing, preventive maintenance, repairs, battery/pad standardization input, and service coordination
• Procurement and supply chain: vendor evaluation, contracting, pricing, lifecycle planning, and consumables sourcing continuity
• Quality and risk management: incident reporting pathways, post-event debrief support, and trend analysis
• IT/security (where connectivity exists): network approval, cybersecurity controls, and device connectivity governance (varies by manufacturer and local policy)

AED programs fail most often not because the technology is complex, but because the system around the technology is not reliably executed.

How do I use it correctly (basic operation)?

A model-agnostic workflow (what is often universal)

Exact prompts and steps vary, but many Automated external defibrillator AED workflows follow this pattern:

1. Ensure scene safety and apply standard precautions per facility policy.
2. Activate emergency response (call for help, code team, EMS) and bring the AED to the patient.
3. Start CPR per your training while the AED is being prepared (team roles help here).
4. Power on the AED (open lid or press power, depending on the model).
5. Expose the chest and prepare the skin: dry moisture, remove excessive hair if needed, and remove items that interfere with pad adhesion.
6. Apply pads in the illustrated positions on the pad package/device (common pattern is anterolateral placement; variations exist by protocol).
7. Connect pads if not pre-connected, and follow voice/visual prompts.
8. Pause touching the patient during analysis when the AED instructs; motion can affect rhythm interpretation.
9. If shock advised, ensure everyone is clear, manage oxygen per protocol, and deliver the shock (button press in semi-automatic units; automatic delivery in fully automatic units).
10. Resume CPR immediately when prompted and continue following the device cycle prompts until advanced help takes over or local termination criteria are met.

This sequence emphasizes a core human-factors principle: the AED should not stop a team from doing high-quality CPR; it should structure the pause-and-shock moments safely.

Setup, calibration, and “settings” (what to expect)

Most AEDs are designed to minimize user-adjustable settings in emergencies. Common points:

• No user calibration is typically required at the time of use; routine checks and self-tests cover readiness (varies by manufacturer).
• Energy selection is usually automated and controlled by the device algorithm; users typically do not choose joules on an AED.
• Some models have a pediatric mode or require pediatric pads/keys; ensure your service has a defined approach for pediatric coverage.
• Volume and screen brightness may be adjustable on some models; others are fixed.
• CPR support features may include a metronome or CPR feedback (rate/depth guidance), depending on the device configuration.

In hospitals, you may also encounter a transition point: once a manual defibrillator/monitor arrives, teams may switch devices. That transition should be governed by local resuscitation policy to avoid delays, duplicated pads, or confusion in documentation.

Semi-automatic vs fully automatic (operational implications)

• Semi-automatic AED: analyzes rhythm and charges; prompts the user to press a shock button if shock advised. This can support team coordination because the operator chooses the moment to deliver after confirming “all clear.”
• Fully automatic AED: delivers the shock automatically after warning prompts. This can reduce the need for a trained operator to press a button, but it requires excellent “hands off” discipline during the charge-and-shock window.

Facilities should consider staff mix, training frequency, and human factors when selecting configurations, where allowed.

What trainees should practice (beyond button-pressing)

Competent AED use includes:

• Clear, loud “stand clear” communication
• Avoiding contact with the patient/bed during analysis and shock
• Fast pad placement with correct orientation
• Recognizing when prompts are being delayed by motion or poor pad contact
• Coordinating compressions so pauses are as short as possible
• Ensuring the AED does not become a single-person task; resuscitation is team-based

How do I keep the patient safe?

Safety practices during analysis and shock

Patient safety and rescuer safety overlap with AED use. Common safety practices include:

• Do not touch the patient during rhythm analysis to reduce artifact and prevent inappropriate decisions.
• Visually confirm “all clear” before shock delivery; this includes hands, stretcher rails, wet sheets, and any equipment contacting the patient.
• Manage oxygen safely per local policy; concentrated oxygen near the chest can increase fire risk in some circumstances.
• Keep pads well-adhered to minimize arcing and skin burns; replace pads if adhesion is poor.
• Avoid pad placement over conductive items or directly over implanted device bulges; adjust based on training and IFU guidance.
• Use the correct patient category (adult vs pediatric) based on device labeling and facility protocol.

Because AEDs are designed for simplicity, a common risk is complacency. Teams should treat the device as powerful electrical hospital equipment and apply the same discipline used with manual defibrillation.

Monitoring and situational awareness (human factors)

AEDs produce authoritative prompts, and “prompt fixation” can occur—teams may follow the device voice while missing other tasks. Practical mitigations:

• Assign a team leader (even in small teams) to maintain situational awareness.
• Use closed-loop communication (repeat back critical commands like “clear” and “shock delivered”).
• Ensure someone is continuously responsible for compressions quality.
• Keep a documentation role where possible, capturing times and interventions per local code documentation standards.

In noisy clinical environments, confirm that prompts are heard:

• Reposition the device if needed
• Increase volume if available
• Rely on visual prompts on screen where present
• Have the operator verbally echo key prompts to the team (“analyzing—hands off”)

Risk controls: labeling, readiness indicators, and standardization

Safety is strongly influenced by how a facility standardizes devices:

• Standardize pad types where possible to reduce wrong-pad events
• Use consistent mounting and signage so staff can find AEDs quickly
• Ensure pads and batteries have visible expiry management
• Keep a simple readiness check list near the device
• Avoid mixing multiple generations/models in the same unit unless training is robust

If your facility uses multiple brands, consider color-coding or location-based standardization to reduce errors.

Incident reporting culture (non-punitive, system-focused)

Unexpected AED behavior—no shock advised, repeated “check pads,” device shutdown—should be handled with a just culture approach:

• Capture what happened, not who to blame
• Preserve the device for review (do not erase logs without a process)
• Engage biomedical engineering early
• Conduct brief, structured debriefs after events to identify training or process gaps

Safety improves when near-misses are treated as learning opportunities.

How do I interpret the output?

Common types of outputs

An Automated external defibrillator AED typically provides:

• Voice prompts (“apply pads,” “analyzing,” “shock advised,” “start CPR”)
• Visual messages and icons that mirror voice prompts
• A decision output: “shock advised” vs “no shock advised”
• A CPR timer/metronome and prompts to resume compressions
• Pad contact indicators or “check electrodes” alerts
• Event records (timestamps, shocks delivered, rhythm snippets) depending on model and configuration
• Some devices include an ECG display, though interpretation is usually not required for basic operation

From an operations perspective, event logs are valuable for quality review, but data access and export methods vary by manufacturer and local policy.

How clinicians typically interpret these outputs

Clinicians should treat AED outputs as decision support within a protocol framework:

• “Shock advised” suggests the algorithm detected a rhythm pattern consistent with a shockable rhythm.
• “No shock advised” does not mean “everything is fine”; it means the AED did not detect a rhythm it is designed to treat with defibrillation. Teams continue CPR and follow escalation protocols.
• Repeated “check pads” or “analysis interrupted” prompts often indicate artifact, poor pad adhesion, or movement rather than a change in patient condition.

For trainees, the key is to avoid over-interpreting. The AED is not a full diagnostic ECG system, and its algorithm is not a substitute for advanced clinical assessment when that is available.

Common pitfalls and limitations

AED interpretation can be challenged by:

• Motion artifact: compressions, patient movement, or transport vibration can disrupt analysis
• Poor pad contact: sweat, hair, inadequate pressure, or expired pads can increase impedance
• Electrical noise: nearby equipment can occasionally interfere (context dependent)
• Unusual rhythms: some rhythms may be misclassified; the details of sensitivity/specificity are manufacturer-specific and not always publicly stated
• Pediatric considerations: detection and energy attenuation approaches differ; follow labeling and protocol
• Implanted devices: pacemaker spikes can be detected on ECG traces and may confuse inexperienced observers (the AED algorithm is designed to handle common scenarios, but performance details vary)

The safest operational approach is to optimize signal quality (good pad placement, hands off for analysis) and follow your resuscitation algorithm.

Why “clinical correlation” still matters

Even with an Automated external defibrillator AED, clinicians correlate outputs with:

• The patient’s responsiveness and breathing pattern
• Team observations (witnessed collapse, downtime estimate)
• Available monitoring (pulse checks per protocol, capnography if in advanced care settings, etc.)
• Reversible causes management where applicable

In short: the AED answers a narrow question (“should I deliver a shock based on this analysis?”), while the team manages the broader resuscitation scenario.

What if something goes wrong?

A practical troubleshooting checklist (during or after an event)

If the Automated external defibrillator AED does not behave as expected, common checks include:

• Device will not power on: verify battery insertion, battery charge status, and that the unit is not in a locked cabinet without access; swap to a spare device per policy.
• “Check pads” / “check electrodes”: confirm pads are fully adhered, not expired, connected properly, and placed on dry skin; replace pads if needed.
• “Analysis interrupted”: ensure everyone is hands off; reduce movement and vibration; follow prompts.
• Shock button won’t deliver (semi-automatic): confirm the device is actually advising shock and is charged; check for “clear” conditions; if persistent, switch to another unit and escalate.
• Low battery warning: continue per prompts while arranging another device; battery behavior varies by manufacturer.
• Device says “service” or error code: remove from service after the event and tag for biomedical engineering review.
• Prompts are inaudible: increase volume if available; use visual prompts; have the operator speak the steps clearly.

During emergencies, facilities should aim for a simple rule: if in doubt about the device, switch to a known-good unit and escalate—but always within local resuscitation and equipment policies.

When to stop use

Stopping AED use is a clinical and safety decision guided by protocol. Non-clinical reasons to discontinue a specific unit include:

• The device is physically damaged or wet in a way that creates electrical risk
• Persistent pad connection failure despite pad replacement
• A service/error indicator that prevents normal operation
• An alternative defibrillation/monitoring device arrives and local protocol requires a transition

Do not attempt ad-hoc repairs in clinical areas. The safest operational posture is to treat malfunctions as medical device incidents until evaluated.

Escalation: biomedical engineering and manufacturer pathways

After the event (or immediately if patient care is compromised), escalation typically includes:

• Biomedical engineering/clinical engineering: quarantine the device, capture serial/asset ID, run functional checks, and coordinate repair
• Manufacturer or authorized service partner: warranty evaluation, service bulletins, or repair/replacement processes (availability varies by region)
• Risk management/quality: assess whether formal incident reporting is required under local rules

Data handling matters. Many devices store event logs; facilities should have a policy on:

• Who downloads data
• Where it is stored
• How it is used for quality improvement
• How privacy and governance are maintained (varies by jurisdiction)

Documentation expectations (general)

A defensible documentation set often includes:

• Time AED applied and prompts followed (per code record format)
• Shocks delivered count (if any) and key timestamps
• Any device issues observed (alerts, failures, pad problems)
• Actions taken (pad replacement, device change)
• Post-event status: cleaned, restocked, tagged out, or returned to service after checks

Strong documentation supports patient safety, training improvement, and equipment lifecycle management.

Infection control and cleaning of Automated external defibrillator AED

Cleaning principles for this clinical device

The Automated external defibrillator AED is generally considered non-critical medical equipment because it contacts intact skin via disposable pads, but the device body is frequently handled and may be exposed to bodily fluids during emergencies. Infection prevention should balance speed (returning the device to readiness) with thoroughness (reducing cross-contamination).

Key principles:

• Single-use pads are disposed of after use; do not attempt to clean and reuse disposable electrodes.
• Clean and disinfect high-touch surfaces after use and per routine schedule.
• Avoid methods that can damage the device (e.g., immersion) unless explicitly permitted in the IFU.

Disinfection vs. sterilization (simple definitions)

• Cleaning removes visible soil and reduces bioburden.
• Disinfection uses chemicals to reduce microorganisms to an acceptable level; most AED surface workflows involve low-level disinfection, depending on exposure risk.
• Sterilization eliminates all microbial life and is generally not applicable to AED main units because they are not designed for sterilization processes.

Always follow your facility’s infection prevention policy and the manufacturer’s IFU, because chemical compatibility varies by plastics, screens, and seals.

High-touch points to prioritize

Focus on areas that are frequently handled during urgent use:

• Handle and carry strap
• Power button/lid latch
• Shock button (if present)
• Screen and navigation buttons
• Pad connector port and cable exterior
• Outer case, cabinet handle, and wall bracket touchpoints
• Accessory pouch zipper/pull tabs

Example cleaning workflow (non-brand-specific)

A practical post-use process many facilities adopt:

1. Don gloves and follow standard precautions per policy.
2. Power off the unit if appropriate and safe (some keep it on until handover is complete).
3. Dispose of used pads and contaminated packaging per clinical waste rules.
4. If visible soil is present, clean first, then disinfect (per disinfectant label contact time).
5. Wipe the device exterior with an approved disinfectant wipe; avoid excess liquid near ports and speaker openings.
6. Allow surfaces to dry fully.
7. Inspect for cracks, damaged connectors, or compromised seals; tag out if damaged.
8. Replace consumables: new pads (in date), battery check, and restock accessories.
9. Document cleaning and readiness check per local process.

For biomedical engineers, cleaning is also a reliability issue: residue in buttons, cracked housings, and fluid ingress can become failure modes.

Medical Device Companies & OEMs

Manufacturer vs. OEM (Original Equipment Manufacturer)

In medical device procurement, the “manufacturer” is typically the legal entity responsible for:

• Design control and risk management documentation
• Regulatory compliance and labeling
• Quality management system oversight
• Post-market surveillance and field safety notices (when applicable)

An OEM (Original Equipment Manufacturer) may:

• Produce a complete device that is sold under another brand (private label)
• Manufacture key components (batteries, electrodes, capacitors, plastics) used by a brand owner
• Provide subassemblies that affect performance and serviceability

OEM relationships can influence:

• Service and parts availability: who can supply batteries, pads, cables, and replacement boards
• Update pathways: software updates, cybersecurity advisories (if connectivity exists), and revision control
• Warranty clarity: who is accountable when failures occur
• Training and manuals: what documentation is available to hospitals and authorized service partners

For procurement and biomedical engineering teams, it is reasonable to ask: Who is the legal manufacturer on the label, and who actually builds key components? The answer varies by manufacturer and contract model.

Key Takeaways and Practical Checklist for Automated external defibrillator AED

• Treat the Automated external defibrillator AED as a time-critical medical device, not a stored accessory.
• Place AEDs based on response time goals, not just available wall space.
• Standardize AED models when possible to reduce training and consumables complexity.
• Ensure every AED has in-date adult pads and a verified battery status.
• Provide pediatric capability only if your policy, training, and supply chain can support it.
• Use daily/shift readiness checks with a simple, auditable log process.
• Train staff to prioritize CPR continuity and minimize hands-off time.
• Teach “hands off for analysis” as a non-negotiable safety behavior.
• Require a loud, explicit “all clear” before any shock delivery.
• Manage oxygen safely during defibrillation per facility protocol and risk controls.
• Keep prep items (towel, razor, gloves, scissors) with the AED for skin preparation.
• Replace pads immediately after use; disposable electrodes are not reprocessable.
• Build a post-event restock workflow that returns the unit to service fast.
• Assign ownership: clinical leader for training, biomed for maintenance, supply chain for consumables.
• Commission each device with asset tags, location mapping, and acceptance testing documentation.
• Schedule preventive maintenance per manufacturer IFU and local engineering policy.
• Verify the legal manufacturer on labeling and clarify OEM/service responsibilities in contracts.
• Include batteries and pads in your inventory system with expiry tracking and reorder points.
• Plan for spare devices or loaners to avoid coverage gaps during repairs.
• Capture device issues as reportable incidents when appropriate, without blame.
• Preserve event data logs per policy for debrief, quality improvement, and governance.
• Teach teams to avoid prompt fixation and maintain overall situational awareness.
• Use closed-loop communication to coordinate shock delivery and compression cycles.
• Confirm pad adhesion and placement before assuming a rhythm analysis problem.
• If repeated “check pads” occurs, replace pads and reduce motion artifact promptly.
• Do not attempt ad-hoc repairs; tag out and escalate to biomedical engineering.
• Clean and disinfect high-touch surfaces after use, avoiding liquid ingress into ports.
• Follow only manufacturer-approved disinfectants and contact times per IFU.
• Ensure cabinets and mounts allow rapid access without key delays during emergencies.
• Align AED locations with code blue workflows and clarify who retrieves the device.
• Audit readiness program performance (missed checks, expired pads, battery failures) periodically.
• Include AED drills in onboarding for non-ICU clinical areas and outpatient sites.
• Require vendors to define service turnaround times, parts availability, and training support.
• Evaluate total cost of ownership, including consumables, batteries, and service contracts.
• Document every use, including device prompts, shocks delivered, and any malfunctions observed.
