Mechanical compression device with adjustable compression point
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.
