A patient support apparatus comprises a plurality of load cells, a frame supported on the load cells, a mattress, a plurality of air pressure sensors, and a control system. The mattress includes a plurality of inflatable zones positioned on the frame, the mattress and frame cooperating to direct any patient load through the mattress and frame to the load cells. Each of the plurality of air pressure sensors measures the pressure in a respective inflatable zone of the mattress. The control system includes a controller operable to receive a separate signal from each of the plurality of load cells and each of the plurality of air pressure sensors and process the signals to identify motion of the patient. The motion of the patient is further processed by the controller to characterize the nature of the patient motion as a high shear motion or a low shear motion, and based on the characterization of the patient motion, the controller automatically updates a patient profile in a patient record or communicates the information with a caregiver.

An inflatable mattress that has multiple chambers is disclosed that includes a first section with a first pressure valve, and a second section that has a plurality of collapsible airtight vertical cylindrical chambers displaced across the first section and which defines a top surface and each vertical chamber includes valves, controlled by a central controller that is programmable and controls the flow of air in and out of each chamber, thereby providing a method to alter the vertical dimension of each chamber and affect movement to a person on the top surface mattress.

The present disclosure provides systems and methods for detecting and monitoring a patient in need of pressure ulcer treatment based on measurements of Sub-Epidermal Moisture (SEM) values.

Methods and apparatus for detecting body vital signs through the use of a Bioelectric Impedance Spectroscopy (BIS), either by (a) direct contact with the person (such as through one or more of their fingers) or (b) measurement of reflections from a field projected into the person's body. The techniques may be implemented using the projected capacitive touch array in a device such as the screen of a smartphone or tablet computer, or the touchpad of a laptop computer.
