Claim 0:
1. A system for monitoring breathing of a patient, the system comprising:
a patient bed configured to support the patient, the patient bed including a mattress having rotation bladders operable to rotate the patient and having percussion and vibration (P&V) bladders operable to loosen and expel secretions from the patient's lungs, wherein the patient bed includes a base, an upper frame assembly, and a lift system coupling the upper frame assembly to the base and operable to raise, lower and tilt the upper frame assembly relative to the base,
a plurality of radar sensors coupled to the patient bed, the plurality of radar sensors being situated above the patient and spaced from the patient, each of the plurality of radar sensors being configured to:
transmit a radar signal towards the patient; and
receive a reflection of the radar signal from the patient, and

circuitry carried by the patient bed and comprising:
a radar controller to receive data from the plurality of radar sensors indicative of the reflection of the respective radar signal from the patient; and
a breathing pattern monitor to determine one or more parameters indicative of a breathing of the patient based on the data from the plurality of radar sensors, wherein the circuitry includes a rotation bladder controller and a P&V bladder controller and wherein the rotation bladder controller and the P&V bladder controller controls operation of the rotation bladders and the P&V bladders, respectively, based on the data from the plurality of radar sensors, wherein the patient bed includes a mast to which the plurality of radar sensors are coupled, wherein a lower end of the mast is coupled to the upper frame assembly so that the plurality of radar sensors coupled to the mast raise, lower, and tilt relative to the base as the upper frame assembly is raised, lowered, and tilted, respectively, by the lift system.
