Embodiment Construction

[0019] Certain details for a thorough understanding of the present invention are listed below. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these details. Furthermore, the specific embodiments of the invention described herein are given by way of illustration and should not be used to limit the scope of the invention to these specific embodiments. In other instances, well-known circuits, control signals, timing procedures, and software operations have not been shown in detail in order not to unnecessarily obscure the present invention.

[0020] FIG. 1 depicts AED 10 employed by user 12 to resuscitate patient 14 after cardiac arrest. In cardiac arrest, otherwise known as sudden cardiac arrest, the patient is struck by a life-threatening interruption of the normal heart rhythm, usually in the form of VF or VT without an overt pulse (ie, shock VT). In VF, the regular rhythmic ventricular contractions are replaced by...

Abstract

A system and method are described for delivering electrotherapy to a patient that includes delivering electrotherapy to defibrillate the patient and providing at least one non-interruptible time period for administration of CPR prior to entering a monitor mode during which a patent cardiac signal is monitored for indication of a shockable rhythm.

Description

technical field [0001] The present invention relates generally to a medical device, and more particularly to an automatic external defibrillator providing a combined monitor and CPR pause mode of operation. Background technique [0002] Defibrillators apply high-amplitude electrical pulses to the heart to restore normal heart rhythm and systolic function in patients with cardiac arrhythmias, such as ventricular fibrillation ("VF") or ventricular tachycardia ("VT") without a discernible pulse. There are many types of defibrillators, including manual defibrillators and automated external defibrillators ("AEDs"). AEDs differ from manual defibrillators in that AEDs automatically analyze a patient's electrocardiogram ("ECG") to determine whether defibrillation is necessary. In nearly all AED designs, the user is prompted to press a shock button to deliver a defibrillation shock to the patient. [0003] AEDs are typically configured to provide audio or visual prompts to the user...
