Abstract
A chest compression monitor for measuring the depth of chest compressions achieved during 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.
Claims12
A system for monitoring the compression of the chest of a patient during CPR, said system comprising:
- 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 module adapted to be held in fixed relationship to a CPR provider's wrist while the CPR provider is manually compressing the patient's chest.
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 module 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 wrist with the releasable fixing mechanism;
- measuring an acceleration signal provided by the accelerometer while the CPR provider is compressing the chest of the patient;
- providing a computer 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.
