Embodiment Construction

[0063] There are many different embodiments of the invention, which cannot be described here. Some preferred possible embodiments are described below. However, it cannot be overemphasized that these are descriptions of embodiments of the invention, not the invention, and are therefore not limited to the specific embodiments described in this section, but rather as defined in the broader claims. terms to describe.

[0064]Referring to Figure 1, one or more sensors or instruments 1, 2, 3 are used to obtain physiological signals of a patient. Certain signals may require preprocessing to derive relevant measurements or to remove artifacts. For example, CPR artifacts can be removed from ECG signals using known techniques. In one such technique, sensor 3 detects when a press actually occurs. The sensor may be an accelerometer housed in a small elastic housing that is placed under the rescuer's hand. Using signal processing methods such as disclosed in pending U.S. Application N...

Abstract

A medical device of the type used for assisting a user in manually delivering repetitive therapy to a patient (e.g., chest compressions or ventilations in cardiac resuscitation), the device comprising a feedback device configured to generate feedback cues to assist the user in timing the delivery of the repetitive therapy, at least one sensor or circuit element configured to detect actual delivery times, at which the user actually delivers the repetitive therapy, and a processor, memory, and associated circuitry configured to compare the actual delivery times to information representative of desired delivery times to determine cue times at which the feedback cues are generated by the feedback device.

Description

technical field [0001] The present invention relates to the field of medical devices used to aid in the delivery of repeated treatments, for example to aid rescuers in performing cardiopulmonary resuscitation (CPR). Background technique [0002] Resuscitation for a victim of cardiac arrest typically involves clearing and opening the patient's airway, administering artificial respiration, and performing chest compressions to direct blood flow to the patient's heart, brain and other vital organs. If the patient has a shockable rhythm, resuscitative management also includes defibrillation. The term "basic life support" (BLS) refers to all of the following: initial assessment; airway maintenance; expiratory ventilation (rescue respiration); and chest compressions. The term "cardiopulmonary resuscitation (CPR)" is used when all three treatments [airway breathing, circulation, including chest compressions] are combined. [0003] There are many different abnormal heart rhythms, s...
