Philips HeartStart FR1

The Philips HeartStart FR1, also referred to as the HeartStream Forerunner, is a semi-automatic defibrillator. The HeartStart FR1 is portable, lightweight, and battery powered. It performs automatic self-tests and displays the results of these test on a status indicator. The FR1 or Forerunner has an LCD screen that displays text prompts, patient and event information, and on some models, and electrocardiogram (ECG). The FR1 determines proper defibrillation pad contact by monitoring impedance between the two disposable defibrillation pads. It recognizes a shockable rhythm based on ECG analysis. The defibrillation shock is delivered using an impedance-compensated biphasic waveform with a minimum of 130 Joules delivered to a 50-ohm load.

Defibrillator

Waveform: Truncated Exponential Biphasic. Waveform parameters are adjusted as a function of patient defibrillation impedance.
Energy: Single Energy—a nominal of 150 Joules (minimum of 130 Joules) delivered to a 50-ohm load.
Charge Control: Under control of the Patient Analysis System for semi-automatic operation. The manual override button allows manual charge control (FORERUNNER Model EM only).
Charge Time: Typically less than 10 seconds. Charge time increases at the end of battery life as well as at temperatures below 10°C.
Shock-to-Shock Cycle Time: Typically less than 20 seconds (including analysis time) in semiautomatic mode.
Shock Discharge Control: Shock is delivered by a single shock button.

Disarming Defibrillator

Semi-automatic operation: Once the device is charged, it will disarm under any of the following conditions: a no shock decision is reached; the on/off button is pressed and the device is turned off; the defibrillation pads are removed from the patient or the pads connector is disconnected from the defibrillator.
Manual operation: Once the device is charged, it will disarm under any of the following conditions: 30 seconds after charging if a shock is not delivered; manually by pressing the manual override button; the on/off button is pressed and the device is turned off; the defibrillation pads are removed from the patient or the pads connector is disconnected from the defibrillator.

ECG Display

Monitored Lead: ECG information is acquired through defibrillation pads in anterior-anterior (Lead II) placement.
Display Range: Differential: ±2 mV full scale nominal.
Sweep Speed: 23 mm/sec. nominal.
Frequency Response (Bandwidth): Nondiagnostic rhythm monitor 1 Hz to 20 Hz (-3 dB) nominal.
Sensitivity: 1.16 cm/mV nominal.
Heart Rate: Displays a range of 30 to 300 beats per minute updated each analysis period. Heart rate is displayed only during monitoring mode and if ECG is displayed.
