The Science of Resuscitation Engineered Into Every Product
Sudden cardiac arrest (SCA) kills more than 350,000 people in the United States every year. The single most predictive variable in SCA survival is time-to-defibrillation — for every minute that passes without defibrillation, survival probability drops approximately 10%. For the majority of SCA events that happen outside a hospital, the first responders are bystanders, security staff, coaches, teachers, and workplace employees — not clinical professionals. The equipment they use in those critical first minutes is not a background detail. It is a clinical intervention with measurable survival impact.
ZOLL Medical Corporation has spent decades engineering that intervention. ZOLL's AED portfolio — available through Medidepot — represents the current state of the art in lay-responder and professional-grade cardiac resuscitation technology. The ZOLL AED Plus with Real CPR Help was the first AED to measure and provide real-time feedback on actual CPR compression depth — a feature that addresses the documented clinical reality that untrained and minimally trained rescuers consistently deliver inadequate compressions without guidance. At Medidepot, the complete ZOLL AED Plus collection gives healthcare facilities, public safety organizations, schools, workplaces, and professional emergency response teams access to ZOLL's full resuscitation product line — from entry-level AEDs to professional-grade defibrillator/monitors used by EMS and hospital-based emergency response teams.
Target Audience — Who Needs ZOLL AED Products?
ZOLL's product range at Medidepot serves distinct audience segments, each with different technical requirements:
• Workplace AED Program Administrators: OSHA and state regulations increasingly mandate AED deployment in workplaces above certain employee thresholds — safety directors and facilities managers need reliable, low-maintenance AEDs that non-clinical staff can operate under stress without prior medical training
• Schools, Universities & Athletic Facilities: sudden cardiac arrest is a leading cause of death in young athletes — school nurses, athletic trainers, and campus safety directors need AEDs that can be deployed quickly in gymnasiums, on athletic fields, and in crowded school buildings by staff with basic first aid training
• Public Safety & Security Professionals: security personnel, building managers, and public safety officers deployed in malls, airports, convention centers, and public spaces are frequently first to arrive at cardiac events — the ZOLL AED Pro bridges the gap between lay-responder simplicity and the advanced rhythm analysis capability that trained responders can utilize
• EMS Agencies & First Responders: the ZOLL R-Series BLS Defibrillator/Monitor is specifically designed for BLS agencies and first responders who need a device that functions as an AED for basic-level providers but converts to a full ALS defibrillator when advanced practitioners are on scene
• Hospitals & Healthcare Facilities: hospital code teams, rapid response teams, and procedure areas use professional-grade defibrillators with monitoring capability — the R-Series BLS and AED Pro meet these requirements with full ECG display and manual defibrillation capability
• CPR Training Programs & Instructors: the ZOLL AED Plus TRAINER II provides a non-delivering training replica of the AED Plus that allows instructors to run realistic AED training drills — with remote control capability for managing multiple training units simultaneously
AED Defibrillators — ZOLL AED Plus Family
ZOLL AED Plus (Semi-Automatic) — with Professional Cover
The ZOLL AED Plus is the flagship semi-automatic AED that introduced Real CPR Help — the world's first AED to measure actual CPR compression depth in real time and provide audio and visual feedback to guide the rescuer. In a semi-automatic AED, the device analyzes cardiac rhythm, determines if a shockable rhythm is present, and prompts the user to press the shock button when a shock is indicated — maintaining user control over the shock delivery decision.
ZOLL Fully-Automatic AED Plus — ZOL 8000-004007-01
The Fully-Automatic AED Plus delivers the same Real CPR Help technology and CPR-D-padz one-piece electrode system as the semi-automatic model — with one critical operational difference: there is no shock button. When the AED determines that a shockable rhythm is present, it prompts everyone to stand clear and delivers the shock automatically. This design eliminates the hesitation that first-time rescuers experience when prompted to press a shock button, and removes the possibility of shock button delay in high-stress bystander response scenarios. The fully automatic configuration is often specified for workplaces with no medical or first-aid trained staff on site, public access locations, and facilities where minimizing the complexity of the rescue sequence is a priority.
• Fully Automatic Shock Delivery: no shock button — the device delivers the shock automatically when shockable rhythm is detected, after clearing prompts, removing the decision burden from the untrained rescuer
• Real CPR Help: compression depth and rate feedback identical to semi-automatic model — guides bystander CPR quality throughout the rescue sequence
• Includes: Medical Prescription, AED Cover, CPR-D-padz electrode, 10× CR123A batteries, and carry case — complete deployment package
ZOLL AED Plus 91687 — Fully Automatic Defibrillator
The 91687 Fully Automatic Defibrillator expands the fully automatic AED option in the Medidepot ZOLL collection, providing an additional fully automatic AED configuration for facilities deploying multiple AED units across large campuses, multi-building facilities, or distributed public access programs where consistent, fully automatic operation across all installed units is a program requirement.
ZOLL AED PRO — ZOL 90110200499991010
The ZOLL AED Pro bridges the gap between lay-responder AED simplicity and the advanced rhythm display and manual capability that trained responders need. The AED Pro features a full ECG display that allows trained first responders — EMTs, security officers with AED training, occupational health nurses, and clinical staff — to view the patient's cardiac rhythm while the device provides automated shock advisory. The AED Pro is the appropriate specification for workplace environments where medically trained staff are likely to be among the first responders, and for public safety organizations deploying personnel with cardiac rhythm recognition training who benefit from ECG visibility during a resuscitation event.
ZOLL AED 3 — 91692
The ZOLL AED 3 is ZOLL's next-generation public access AED with a full-color display and improved user guidance system designed to further reduce the cognitive load on first-time rescuers. The AED 3's color screen provides clearer visual guidance through each step of the rescue sequence — including CPR coaching with real-time feedback — in a format that first-time users can follow more intuitively under stress. The AED 3 is specified for public access programs, workplace deployments, and facilities updating aging AED fleets to current-generation technology with enhanced rescuer guidance.
Powerheart G5 AED (91697) — Fully Automatic Defibrillator
The Powerheart G5 is a fully automatic AED available in the Medidepot ZOLL collection, providing an additional fully automatic defibrillator option for facilities building multi-unit AED programs. The G5's fully automatic operation delivers the shock without a shock button when a shockable rhythm is confirmed — consistent with the program preference for fully automatic devices in unmanned public access locations, unmonitored facilities, and settings where maximum simplicity of operation is the overriding deployment criterion.
Professional Clinical Systems
ZOLL R-Series BLS Defibrillator/Monitor — ZOL 30210000001030013
The ZOLL R-Series BLS is the professional-grade defibrillator/monitor designed for BLS emergency response agencies, hospital rapid response teams, and clinical settings where the resuscitation device must serve both basic life support providers and, when advanced practitioners arrive, function as a full-featured ALS defibrillator without equipment changeover.
The R-Series BLS's dual-mode design is its defining clinical value: powered on, it operates as an AED for BLS-level responders — analyzing rhythm, advising on shock delivery, and coaching CPR quality. One button press converts it to a full ALS defibrillator with manual defibrillation, pacing capability, and full ECG display for advanced providers. This single-device approach eliminates the equipment transition delay that occurs when an ALS team arrives at a scene where a BLS team has been managing the arrest with a separate AED.
Training
ZOLL AED Plus TRAINER II — ZOL 8008-0050-01
The ZOLL AED Plus TRAINER II is a non-delivering training replica of the AED Plus designed for CPR and AED training programs in workplaces, schools, healthcare facilities, and public safety organizations. The TRAINER II simulates the full operational sequence of the AED Plus — voice prompts, electrode placement guidance, CPR coaching, and shock sequence — without delivering an actual electrical shock, making it safe for repeated use on live training participants.
• Remote Control Operation: the included remote allows a single instructor to control multiple TRAINER II units simultaneously — advancing scenarios, triggering different rhythm presentations, and managing group training sessions without individually handling each device
• Full Simulation Fidelity: accurately replicates the AED Plus user experience, ensuring that training on the TRAINER II directly translates to confident operation of the actual AED Plus in an emergency
• Program Value: regular AED training with the TRAINER II is the most direct intervention for improving first-responder confidence and reducing the time-to-first-shock delays that cost lives in witnessed cardiac arrests

For EMS agencies and hospitals managing multiple R-Series units, the SurePower system is an essential component of the preventive maintenance and readiness assurance program.
Type 123 Lithium Batteries 10-Pack — 8000-0807-01
The CR123A 10-pack is the standard battery supply for ZOLL AED Plus and Fully-Automatic AED Plus devices. CR123A lithium batteries provide the long-term shelf stability and reliable cold-start performance that AED power management requires — ZOLL specifies a 5-year battery service life for the AED Plus. For facilities maintaining multiple AED Plus units on a battery replacement schedule, the 10-pack format supports efficient inventory management and ensures that replacement batteries are on hand when devices require servicing.
Real CPR Help — The Technology That Defines ZOLL AEDs
The single most clinically significant differentiator in the ZOLL AED Plus product line is Real CPR Help — a technology that fundamentally changes what an AED does during a cardiac arrest beyond defibrillation. Clinical research consistently demonstrates that bystander CPR compressions are frequently too shallow, too slow, or too fast — and without real-time feedback, rescuers have no mechanism to correct their technique during an active resuscitation.
• Accelerometer-Based Depth Measurement: the CPR-D-padz electrode contains an accelerometer sensor positioned at the rescuer's hand placement point — it measures the actual depth of every compression and transmits this data to the AED in real time
• Real-Time Audio & Visual Feedback: the AED provides coaching prompts — 'Push Harder,' 'Good Compressions,' 'Push Faster/Slower' — updated with each compression cycle, guiding the rescuer toward the depth (at least 2 inches) and rate (100–120 per minute) recommended by current AHA guidelines
• CPR Fraction Improvement: Real CPR Help also tracks the proportion of time that compressions are being performed versus paused, supporting the high chest compression fraction that resuscitation science identifies as a key determinant of survival outcomes
• Clinical Impact: studies demonstrate that rescuers using Real CPR Help deliver measurably better compressions than those using AEDs without feedback — which translates directly to improved coronary perfusion pressure and increased probability of return of spontaneous circulation (ROSC)
Frequently Asked Questions
Q1: What is the difference between the ZOLL AED Plus semi-automatic and fully automatic versions?
The semi-automatic AED Plus prompts the user to press a shock button when needed. The fully automatic version delivers the shock automatically without a button — ideal for untrained bystanders or unmanned locations where maximum simplicity reduces rescue hesitation.
Q2: What is Real CPR Help and why does it matter for cardiac arrest survival?
Real CPR Help uses a sensor in the CPR-D-padz electrode to measure actual compression depth and rate, providing real-time audio/visual feedback. This guides untrained rescuers to deliver clinically effective compressions — directly improving coronary perfusion and ROSC probability.
Q3: What makes the ZOLL R-Series BLS different from the AED Plus?
The R-Series BLS is a professional defibrillator/monitor with ECG display, 200J energy, manual defibrillation, and ALS conversion. The AED Plus is a public-access AED for lay responders. The R-Series is designed for EMS, rapid response teams, and hospital code teams.
Q4: How long do the batteries and electrodes last in the ZOLL AED Plus?
ZOLL specifies approximately 5 years for CR123A lithium batteries and 5 years shelf life for CPR-D-padz electrodes. Regular self-test checks by the AED confirm readiness status — replace batteries and electrodes before expiration to maintain compliance.
Q5: Can non-medical staff use the ZOLL AED Plus TRAINER II for workplace AED training?
Yes. The TRAINER II is designed for lay-responder training — it simulates the full AED Plus sequence without delivering a shock. The instructor remote controls multiple units simultaneously, making it ideal for large group workplace CPR/AED training sessions.
