CPR chest compression monitor
First Claim
1. A system for facilitating the effective administration of cardiopulmonary resuscitation (CPR), said system comprising:
- an accelerometer for producing an acceleration signal indicative of the displacement of a CPR recipient'"'"'s chest toward the recipient'"'"'s spine;
a microprocessor being programmed to convert the acceleration signal into a distance value and compare the distance value to a desired range;
a signaling mechanism, operably connected to the microprocessor, for indicating when the distance value is within the desired range;
a tilt compensator comprising a tilt sensor mechanism for outputting a tilt compensation signal indicative of the extent of tilt of the accelerometer; and
wherein the microprocessor is also programmed to adjust the distance value to account for the tilt compensation signal.

Abstract
Chest compressions are measured and prompted to facilitate the effective administration of CPR. A displacement detector produces a displacement indicative signal indicative of the displacement of the CPR recipient'"'"'s chest toward the recipient'"'"'s spine. A signaling mechanism provides chest compression indication signals directing a chest compression force being applied to the chest and a frequency of such compressions. An automated controller and an automated constricting device may be provided for applying CPR to the recipient in an automated fashion. The automated controller receives the chest compression indication signals from the signaling mechanism, and, in accordance with the chest compression indication signals, controls the force and frequency of constrictions. The system may be provided with a tilt compensator comprising a tilt sensor mechanism outputting a tilt compensation signal indicative of the extent of tilt of the device, and may be further provided with an adjuster for adjusting the distance value in accordance with the tilt compensation signal. An ECG signal processor may be provided which removes the CPR-induced artifact from a measured ECG signal obtained during the administration of CPR.
