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: Examples of the disclosure are directed to mechanical compression devices that can adjust a location of a compression position relative to a patient. One or more of the mechanical compression devices can adjust the compression position in an adjustment plane that is generally perpendicular to a patient. Some of the mechanical compression include support columns that have actuators that can be set asymmetrically to adjust the compression position and/or can be tilted relative to the backboard to adjust the compression position. Other examples includes mechanical compression devices that have multiple actuators that can be used to adjust the compression position as well as provide compressions.
