DescriptionMore Details

ECG Monitoring Patient connection: 3-lead ECG cable, 5-lead ECG cable, 12-lead ECG cable, paddles or MFE pads. Input protection: fully defibrillator protected. Special circuit prevents distortion of ECG by pacer pulse. (Pacer version only). Implanted pacemaker spike display: dedicated circuitry detects most implanted pacemaker spikes and provides standard display marker of spike on ECG trace. ECG size: 0.5, 1, 1.5, 2, 3 cm/mV. Heart rate: digital display 0-300 bpm ±5%. Heart rate alarm: On/Off displayed on monitor. User selectable, tachycardia 60-280 bpm, bradycardia 20-100 bpm
Display Screen type: high-resolution display. Screen size: 5″ (12.7 cm) diagonally. Information: heart rate, lead/pads, alarm on/off, NIBP, 12-lead ECG, SpO2, EtCO2, AED functions and prompts, defibrillator test function, self test function, error corrections and faults, pacer functions (optional), code markers, alarm selection and limits, delivered energy.
Defibrillator Waveform: damped sinusoid or ZOLL rectilinear biphasic. Energy selection: selectable at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 50, 75, 100, 150, 200, 300, 360 Joules selected using controls on sternum paddle or device front panel. Rectilinear biphasic energy selection up to 200 joules maximum. Charge time: less than 7 seconds with a new fully charged battery. Depleted batteries will result in a longer defibrillator charge time. Energy display: monitor display indicates both selected and delivered energy. Synchronized mode: synchronizes defibrillator pulse to patient’s R-wave. “SYNC” message displays on monitor. Marker on display and recorder paper identifies R-wave discharge points. Advisory function: single analysis or programmable auto re-analyze x3 with programmable auto energy level selection, screen prompts, and voice prompts. Change controls on apex paddle and device front panel. . Paddles: external anterior/anterior adult and pediatric paddles. Adult paddles slide off to expose pediatric paddles. Defibrillator advisory: evaluates electrode connection and patient ECG to determine if defibrillation is required
Pacemaker (Pacer version only) Type: VVI demand; asynchronous (fixed rate) when used without ECG leads or in ASYNC pacing mode. Pulse: rectilinear, constant current; 40msec ±2; amplitude variable 0 to 140 mA ±5%, whichever is greater; digitally displayed on the monitor; rate variable from 30 to 180 ppm ±1.5%. Fully defibrillator protected and isolated.
Recorder Paper: 80 mm thermal (grid width), 90 mm(paper width). Annotations: time, date, defib energy, heart rate, pacer out (pacer version only), QRS sync marker, ECG size, lead, alarm, defib test Ok/Fail, analyze ECG, analysis halted, noisy ECG, shock advised, no shock advised. ECG too large, ECG too small, and diagnostic bandwidth
General Size: 6.8″ (17.3 cm) high x 10.3 in (26.2 cm) wide x 8.2 in (20.8 cm) deep. Weight: 11.5 lbs (5.23 kg) with Size: 6.8″ (17.3 cm) high x 10.3 in (26.2 cm) wide x 8.2 in (20.8 cm) deep. Weight: 11.5 lbs (5.23 kg)

General Information About Defibrillators

Why Defibrillation?

  • Sudden Cardiac Arrest (SCR)-Rapid irregular rhythm causing heart to quiver
  • Cause: Ventricular Fibrillation (VF)
    • Can lead to death if emergency shock not delivered
  • Defibrillation – to counteract fibrillation


  • Device used to administer an electric current (shock) to the heart
  • Types of Defibrillators
    • Manual external
    • Manual Internal
    • Automated External (AED)
    • Semi-Automated External
    • Implantable Cardioverter-Defibrillator (ICD)

Manual External Defibrillator

  • Widely used in Hospitals and clinics
  • Inbuilt EKG reader
  • Clinician Diagnoses the condition and accordingly administers the shock through paddles or pads

Manual Internal Defibrillator

  • Exclusively used in Operation Theatres
  • Charge delivered through internal paddles in direct contact with the heart

Automated External Defibrillator (AED)

  • Used by lay persons requiring little training
  • Built in heart rhythm analyzer
  • Advices whether shock is required

Semi-Automated External Defibrillators

  • Used by paramedics and emergency medical technicians
  • Automated capabilities of AED
  • With ECG display and manual over ride option

Implantable Cardioverter Defibrillator

  • Implants similar to pacemakers
  • Constantly monitor heart rhythm
  • Automatically administers shock for arrhythmias

Types of waveform – Shape of defibrillation current

  • Monophasic damped sine waveform – delivers energy in one direction
    • Relies on adjustment of joule settings
  • Biphasic damped sine waveform – bi-directional current flow
    • Measures impedance of patient and delivers precise dose of electricity
    • Uses significantly low energy levels
    • Decreases risk of burn in Myocardial damage
