Estimating the term…
A CPR machine (100) is configured to perform compressions on a patient's (182) chest that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A compression force may be sensed, and the driving is adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected. An advantage is that a changing condition in the patient or in the retention of the patient within the CPR machine may be detected and responded to.
A Cardio-Pulmonary Resuscitation (“CPR”) machine configured to perform, on a chest of a supine patient, compressions alternating with releases, the chest having an initial resting height above a reference elevation level, the initial resting height determined at a moment when none of the compressions is being performed, the CPR machine comprising:
A non-transitory computer-readable storage medium storing one or more programs which, when executed by a Cardio-Pulmonary Resuscitation (“CPR”) machine configured to perform, on a chest of a supine patient, compressions alternating with releases, the CPR machine including a compression mechanism configured to perform, when driven, the compressions to the chest and the releases, a driver system, and a force sensing system, the chest having an initial resting height above a reference elevation level, the initial resting height determined at a moment when none of the compressions is being performed, the programs result in operations comprising:
A method for a Cardio-Pulmonary Resuscitation (“CPR”) machine to perform, on a chest of a supine patient, compressions alternating with releases, the CPR machine including a compression mechanism configured to perform, when driven, the compressions to the chest and the releases, a driver system, and a force sensing system, the chest having an initial resting height above a reference elevation level, the initial resting height determined at a moment when none of the compressions is being performed, the method comprising:
