The following are definitions of terms related to LIFEPAK® 15:

Biphasic Waveform 

  • Characterized by a positive current phase followed by a reverse current phase of shorter duration and decreased magnitude. The waveform pulse characteristic is biphasic truncated exponential (BTE)

Automated External Defibrillator (AED) 

  • An Automated ECG analysis and a prompted treatment protocol for patients in cardiac arrest

Shock Advisory System (SAS)

  • A computerized ECG analysis system used in AED mode for detecting a shockable rhythm

Continuous Patient Surveillance system (CPSS)

  • A feature that monitors the patient ECG in LEADS or PADDLES for a potentially shockable rhythm. CPSS is active when the VF/VT ALARM is selected ON (Setup/Alarms) or after pressing the ALARMS button


  • A summary report that includes the ECG segments associated with key events, such as analysis or shock

CO2 Monitor

  • An optional noninvasive capnometer that monitors CO2, EtCO2, FiCO2, and respiration rate (referred to henceforth as CO2)

End-Tidal Carbon Dioxide (EtCO2)

  • EtCO2 is the measurement of CO2 at the end of expiration

Event Log Summary

  • A report summarizing important events for a particular patient record; part of the CODE SUMMARY report

Noninvasive Blood Pressure (NIBP)

  • An optional oscillometric measurement of systolic, diastolic, and mean arterial blood pressure, along with pulse rate

Noninvasive Pacing

  • A standard feature that delivers repetitive electrical stimuli to the heart through large adhesive electrodes placed on the patient’s chest

QUIK-COMBO ® Pacing/Defibrillation/ECG Electrodes

  • An electrode system that allows monitoring of ECG, delivery of pacing and defibrillation therapy to the patient

QUIK-COMBO Patient Simulator

  • A combination QC therapy cable and ECG lead cardiac rhythm simulator. The simulator is designed for use in training clinical personnel to operate the LIFEPAK 15 monitor/defibrillator

Pulse Co-Oximeter

  • An optional noninvasive pulse oximeter that measures the saturation of oxygen in arterial blood, carboxyhemoglobin and methemoglobin concentrations, respectively


  • The measure of functional oxygen saturation (SpO2), carboxyhemoglobin concentration (SpCO), and methemoglobin concentration (SpMet) in the blood

Test Load

  • An accessory shipped with the LIFEPAK monitor/defibrillator that connects to the QUIK-COMBO therapy cable. It provides a 50 ohm load for shock discharge through the therapy cable

Vital Sign (VS) and ST Segment Trends

  • An optional trending feature that can graphically display and document a patient's vital signs and ST segment measurements for up to eight hours.
