Information
The Heartstart 911 is a lightweight, portable, battery-powered, semi-automatic Defibrillator. When connected to a patient via cables and self-adhesive defibrillation electrodes and turned on, the Heartstart 911 prompts the operator to take specific actions, analyses the ECG, charges the shock capacitors and indicates whether a shockable rhythm is present. The operator discharges the device. The Heartstart 911 is intended for use by emergency care personnel who have completed training and certification requirements applicable to the use of a Defibrillator. It is specifically designed for use in early defibrillation programme with medically approved patient-care protocols. The recognition of a shockable arrhythmia, ventricular fibrillation, (or rapid ventricular tachycardia), is based on the Heartstart 911 ’s ECG analysis system. ECG signals are acquired via two disposable, defibrillation electrodes. Contact between the electrodes and the patient is monitored to ensure proper electrode contact. Discharge energy levels of 200, and 360 joules are available. Power is provided from an easily exchanged, rechargeable, sealed lead-acid battery installed in the side of the Heartstart 911. For further battery maintenance details see page 22. If the Heartstart 911 is being charged with a Heartstart battery charger, an automatic device selftest can be performed at regular intervals. Device status, warnings, and operating messages are presented on a two-line display. Three pushbuttons are used to operate the device. Voice messages or “prompts” reinforce important displayed messages. Internal memory in the Heartstart 911 records information about device operation and stores up to 150 seconds of a patient's ECG that can be downloaded to a Medical Control Module Plus. The Medical Control Module Plus can store up to 20 minutes of a patient's ECG in its memory for later printing of a report. Printing is performed by separate equipment.
