First Claim
Patent Images
1. A method for monitoring the compression of the chest of a patient during CPR, said system comprising:
- providing a chest compression monitor comprising an accelerometer adapted to sense upward and downward acceleration of the chest compression monitor, said compression monitor further adapted to output an acceleration signal indicative of the upward and downward acceleration of the chest, said compression monitor housed in a housing fixed to a releasable fixing mechanism for fixing the module to the CPR provider'"'"'s wrist;
attaching the chest compression monitor to a CPR provider'"'"'s first hand, with the housing of the chest compression monitor disposed on the dorsal surface of the first hand with the releasable fixing mechanism;
performing CPR chest compressions by placing the CPR providers second hand on the patient'"'"'s chest, and placing the CPR provider'"'"'s first hand on top of the second hand, with the chest compression monitor atop the dorsal surface of the first hand, and thereafter providing numerous CPR chest compressions with the CPR provider'"'"'s hands;
measuring an acceleration signal provided by the accelerometer while the CPR provider is compressing the chest of the patient;
providing a microprocessor operable to process the acceleration signal to determine the depth of chest compression and produce a compression signal indicative of the depth of compression of the patient'"'"'s chest, and processing the acceleration signal to determine the depth of chest compression and produce a compression signal indicative of the depth of compression of the patient'"'"'s chest.

Abstract
A chest compression monitor for measuring the depth of chest compressions achieved during CPR. A displacement detector produces a displacement signal indicative of the displacement of the CPR recipient'"'"'s chest toward the recipient'"'"'s spine. A signaling mechanism provides chest compression indication signals prompting a CPR provider to provide a chest compression force at a desired depth and rate. The device is held to the dorsal surface of the hand during use and provides a display for feedback, which is readily visible to the CPR provider.

21. A system for monitoring the compression of the chest of a patient during CPR, said system comprising:
personnel identification badge or card comprising an identification card or badge adapted to be worn by a CPR provider, said identification badge or card comprising a housing containing an accelerometer adapted to sense upward and downward acceleration of the badge or card and output an acceleration signal indicative of the upward and downward acceleration of the chest, a microprocessor programmed to receive the acceleration signal and determine from said acceleration signal the depth of compressions being provided by a CPR provider, and a display operable by the microprocessor for display of chest compression depth achieved by the CPR provider, said badge or card being adapted to be held in fixed relationship to a dorsal surface of a CPR provider'"'"'s hand while the CPR provider is manually compressing the patient'"'"'s chest, and a releasable fixing mechanism for attaching the badge or card to a CPR provider'"'"'s hand while said CPR provider is performing CPR compressions while holding the badge or card such that the display is visible to the CPR provider. - View Dependent Claims (22, 23, 24, 25)
