A patient support system with chest compression system and harness assembly with sensor system. The harness assembly secures shoulders and hips of the patient on a patient support surface during transport. A chest compression system is integrated into the harness assembly in a manner that provides chest compressions to the patient while the patient is secured on the patient support surface. The tension of the harness assembly is selectively adjusted and/or a fluid bladder may be selectively expanded. A controller is in communication with the chest compression system and controls operation of the chest compression system. The sensor system is integrated into the harness assembly and in communication with the controller. The chest compression system may be removable from the harness assembly via an adapter. The chest compression system may be integrated into the patient support apparatus to secure the patient to the patient support surface while providing chest compressions.

A patient support apparatus comprises a support structure comprising a base and a patient support surface to support a patient. An actuator system facilitates movement of the patient support surface relative to a floor surface. One or more sensors are responsive to changes in position of the patient support surface caused by the actuator system. A controller is operably coupled to the one or more sensors and the actuator system. The controller is configured to operate the actuator system to move the patient support surface and to monitor the movement of the patient support surface by sensing positions of the patient support surface over time. The controller is further configured to identify a frictional load event on the actuator system during movement in a present cycle and associate the frictional load event with a sensed position of the patient support surface in the present cycle.
