1. A system for monitoring movement of a patient, the system comprising:
one or more radar sensors configured to:
transmit a radar signal towards a patient on a patient bed; and
receive a reflection of the radar signal from the patient, and
circuitry comprising a patient position monitor to:
receive data from the one or more radar sensors indicative of the reflection of the radar signal from the patient; and
determine a position parameter of the patient, wherein the position parameter is indicative of a location or orientation of the patient on the patient bed,
wherein the circuitry further comprises a percussion and vibration (P & V) bladder controller to: determine, based on the position parameter, a subset of a plurality of P & V bladders of the patient bed to inflate in order to perform P & V therapy on the patient, wherein the selected subset of the plurality of P & V bladders are P &V bladders under a current position of the patient; and send a signal to inflate the subset of the plurality of P & V bladders,
wherein the one or more radar sensors are further configured to: transmit an additional radar signal towards the patient during the P & V therapy; and receive a reflection of the additional radar signal from the patient, and wherein the P & V bladder controller is further configured to: receive additional data from the one or more radar sensors indicative of the reflection of the additional radar signal from the patient; determine, based on the additional data from the one or more radar sensors, an amplitude of vibration of the patient caused by the P & V therapy; and adjust a signal sent to inflate the subset of the plurality of P & V bladders based on the amplitude of vibration of the patient.
