Zoll E Series

Defibrillator / Monitor / Pacer

If you are searching for a cost-effective solution for your medical team, E LECOTEK has the right equipment for you.

The ZOLL E Series products were designed to withstand the roughest conditions, whether it is below-zero temperatures, heavy rain, heat, drops or extreme forces. Its compact and lightweight design makes it the ideal companion for every member of the emergency medical services team.

All E Series products are equipped with a high-resolution LCD that has three operating modes for maximum readability: color, black on white, white on black. Whether in darkness or direct sunlight, the information on the screen is always easy to read.

The following table shows the main advanced capabilities of the E Series. Zoll E Series


Depending on the configuration, E Series products can display, record, or print 3-lead or 12-lead ECGs.

Advanced monitoring capabilities allow measurement of vital parameters:

  • Non-invasive Blood Pressure (NiBP)
  • End-tidal carbon-dioxide (etCO2) via main-stream or low-flow side-stream
  • Pulse-oximetry (SpO2)
  • Carboxyhemoglobin saturation (SpCO)
  • Methemoglobin saturation (SpMet)

The defibrillation unit of the E Series products provides advanced functionality for advanced cardiovascular life support (ACLS) or basic life support (BLS):

  • Automated External Defibrillator (AED) – only defib mode for BLS
  • Advisory Defibrillation for detecting a shockable rhythm
  • Manual Defibrillation
  • Synchronized Cardioversion by detecting the patient’s R-waves

Additional Technology

  • Real CPR Help® - provides feedback about the quality of CPR derived from compression rate and depth measurement.
  • See-Thru CPR® - suppresses ECG artifacts induced by CPR compressions

Noninvasive Transcutaneous Pacing (NTP)

Bluetooth Optional, wireless Bluetooth communication with a ZOLL-approved host system (handheld device or PC running ZOLL Data Relay software)

The ZOLL E Series is the most versatile and sturdiest piece of equipment that was ever built. Staff in critical care, in the emergency room, or paramedics on the road, value its reliability and usefulness. Worldwide, it has become the most frequently used portable monitor and treatment device.


Whenever a critically-ill patient needs to be transported from one location to the other, the E Series delivers important information about the patient’s respiratory and cardiovascular status. It continuously or intermittently monitors these vital parameters: 3-lead or 12-lead ECG, SpO2 (optional SPCO, SpMet), NiBP, and end-tidal CO2. Depending on the type of batteries (sealed lead acid, Lithium ion, NiCd), the operating time varies between 2,75 and 4.25 hours.

Rescue teams value its ability to provide a quick print-out for documentation purposes or use the optional PCMCIA card for recording and transferring all obtained data for later analysis with RescueNet Code Review on a Windows PC.

The inbuilt GE Medical Systems Information Technologies 12SL Analysis Program (if configured) provides an automated ECG analysis with interpretation.


The E Series’ 12-lead ECG capability enables quick on-site identification of ST-Segment Elevation Myocardial Infarction (STEMI) to activate a “Code STEMI” at the nearest hospital.

In case of a sudden cardiac arrest, the advisory function of the defibrillator analyzes the ECG for a shockable rhythm.

Pulse-oximetry and co-oximetry help to immediately detect hypoxia and detect life-threatening carbon monoxide and methemoglobin intoxication.

Capnometry provides invaluable information about the patient’s respiratory status. In addition, end-tidal CO2 helps to identify the correct position of the intra-tracheal tube if the patient requires intubation and ventilation.


Depending on the version (ACLS or BLS) the defibrillator can be run in different modes:

  • Manual Mode
  • Advisory Mode
  • AED Mode
  • Synchronized Cardioversion

The E Series uses a biphasic waveform as it is standard now. Research has shown that a truncated or rectilinear

biphasic waveform has greater shock efficacy in patients with ventricular fibrillation (Review by Nichol et al., JACC, Dec. 2017).

The AED and advisory mode of the E Series automatically recognizes a shockable rhythm, e.g. pulseless ventricular tachycardia (VT) and ventricular fibrillation (VF). The machine displays all relevant commands on the screen and uses voice prompts to alert and instruct the emergency staff.

In case of an in-hospital cardiac arrest, skilled personnel trained in ACLS must exclude contraindications as follows:

  • Dysrhythmias due to enhanced automaticity (digitalis toxicity, catecholamine-induced arrhythmia)
  • Multifocal atrial tachycardia

In these conditions cardioversion is associated with a higher incidence of post-shock VT and VF.

The E Series is also capable of synchronized defibrillation (Softkey: SYNC ON) by discharging the shock with the next detected R wave. This helps to avoid the vulnerable T-wave segment of the cardiac cycle. Indications for electrical cardioversion include supraventricular tachycardia (SVT), atrial fibrillation or flutter, and VT with pulse.

CPR Assistance

Real CPR Help®

The American Heart Association (AHA) Guidelines for CPR and ECC emphasize the importance of high-quality CPR. Chest compressions must be applied at an adequate rate and depth. The recommended chest compression rate is 100 to 120 per min. The depth of the chest compression adults should be at least 2 inches (5 cm) but not greater than 2.4 inches (6 cm). When used with CPR-D•padz, the E Series applies a Real CPR Help® algorithm to provide rescuers with feedback about the quality of the delivered CPR. The Real CPR Help® uses the following to achieve high-quality CPR:

  • CPR Compressions Indicator
  • CPR Idle Time Display
  • CPR Rate Metronome
  • Voice prompts
  • Chest Compressions Bar Graph

See-Thru CPR®

Chest compressions inject CPR artifacts into the ECG signal. Without the See-Thru CPR® algorithm, the rescuers has no other choice then interrupting the CPR once in a while to assess whether the patient’s ECG has returned to a normal or near-normal rhythm, in conjunction with estimating cardiac output.

When using CPR-D•padz electrodes, the See-Thru CPR algorithm applies a filter for removing the CPR artifacts from the ECG signal which helps to maximize the amount of resuscitation.  

In some cases, such as asystole or low amplitude PEA, the residual artifact seen after filtering may look like fine ventricular fibrillation. If in doubt, the rescuer should always follow the standard procedure of stopping CPR to assess the patient’s ECG rhythm.

Non-invasive Transcutaneous Pacing (NTP)

In case of severe bradycardia, the pacer version of the E Series can deliver three types of pacing

  • Demand pacing with ventricular pacing rate above patient’s intrinsic rate
  • Stand-by pacing with ventricular pacing rate below patient’s intrinsic rate as a backup
  • Asynchronous pacing, if no ECG electrodes can be placed, e.g. burns patients (ASYNC ON)

The Multi-Function Electrode (MFE) Pads are attached to the thorax place in an anterior (pre-cordial) and posterior position. The E Series pacemaker allows for continuous adjustment of the output current between 0 and 140 mA. The pacing rate is continuously variable from 30 to 180 pulses per minute (ppm).

Transmission of 12-Lead ECG

Some of the E Series systems offer Bluetooth capability for wireless transmission of the 12-lead ECG.

Zoll E Series ECG Transmit

This enables EMS staff to transmit ECGs to the hospital ahead of patient arrival. The ECG arrives within seconds in the software system of the receiving emergency or cardiology department.
