Abstract
An automated external defibrillator (AED) is described which spends an increased proportion of a rescue in a CPR mode. This is accomplished by use of a single shock protocol which causes the AED to spend less time in shock analysis and delivery activities as compared with the typical multiple shock protocol. An AED of the present invention preferably is configured such that the rescue protocol can be modified or changed easily without the need to remove the battery or use specialized hardware or software. Preferably the shock waveform of the single shock is a biphasic waveform delivering at least 150 Joules of energy and more preferably at least 200 Joules of energy.
Claims15
An automatic external defibrillator (AED) comprising:
- a pair of electrode pads;
- an ECG processor coupled to the electrode pads and operable to analyze ECG signals to determine whether a shock is advised;
- a high voltage circuit coupled to the electrode pads for the delivery of a biphasic defibrillation shock when a shock is advised;
- a battery coupled to power circuitry of the AED;
- a treatment protocol store which stores a treatment protocol by which the AED is controlled to deliver a single biphasic defibrillation shock in a first shock sequence followed by-multiple shocks in a second shock sequence, wherein the first shock sequence and the second shock sequence are always separated by a CPR period during which no defibrillation shock can be delivered;
- and
- a controller coupled to the treatment protocol store which operates to execute the treatment protocol.
