Automated CPR Chest Compression Device with Feedback from a Chest Compression Monitor

A chest compression system for providing CPR chest compressions on a patient, said system comprising:

• a chest compression device comprising a piston and means for driving the piston to impact the patient's chest at a resuscitative rate;
• a compression monitor disposed in relation to the piston such that it experiences the downward and upward acceleration of the chest compressions provided by the chest compression device, said compression monitor comprising an accelerometer and processing means for determining, from an acceleration signal provided by the accelerometer, the depth of compressions achieved by the means for driving the piston;
• and
• an automated controller for operating the means for driving the piston, said control system being programmed to control the chest compressions applied to the patient's chest in response to the acceleration signal provided by the accelerometer.

A chest compression system for providing CPR chest compressions on a patient, said system comprising:

• a chest compression device comprising a piston and a motor for driving the piston to impact the patient's chest;
• a compression monitor disposed in relation to the piston such that it experiences the downward and upward movement of the chest compressions provided by the chest compression device, said compression monitor operable to provide chest compression indication signals indicative of the depth of compressions achieved by the chest compression device;
• and
• an automated controller for operating the motor, said automated controller being operable to control the chest compression device in response to the chest compression indication signals.
