Abstract: Techniques and devices for extending a piston and/or compression unit, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

Abstract: A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be 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.

Abstract: A CPR chest compression machine includes a retention structure configured to retain a patient's body, and a compression mechanism configured to perform automatically CPR compressions to the patient's chest. The CPR machine also includes a camera coupled to the retention structure or to the compression mechanism. The camera has a field of view that spans at least a certain portion of the patient's body, and is configured to acquire an image of what is spanned by its field of view. The image may be stored in a memory, displayed, transmitted, analyzed to diagnose the patient, detect shifting of the patient within the CPR machine, etc.
