Patent attributes
Devices and methods for compressing a chest of a patient includes a platform for placement under a thorax of the patient, a compression belt for extending over an anterior chest wall of the patient, a drive train operably connected to the compression belt, a motor operably connected to the compression belt through the drive train, and a control system configured to control operation of the motor to cause the drive train to tighten and loosen the compression belt in repeated cycles of compression about the thorax of the patient. Each cycle of the repeated cycles includes tightening the compression belt around the chest of the patient after tightening, causing, by the control system, the motor to cease operation of the drive train for a hold period; and at a termination of the hold period, loosening the compression belt around the chest of the patient.
