Abstract
A patient support apparatus comprising a patient support deck, a touchscreen, and a controller. The patient support deck comprises a patient support surface. The touchscreen comprises a screen, an input surface arranged adjacent to the screen, and a touch sensor configured to generate an electric field within an envelope defined adjacent to the input surface to sense conductive objects interacting with the electric field. The touch sensor is operable at a first sensitivity level to detect conductive objects approaching the input surface, and a second sensitivity level to detect conductive objects engaging the input surface. The controller is in communication with the touchscreen to operate the touch sensor at the first sensitivity level during an absence of conductive objects interacting with the electric field, and to operate the touch sensor at the second sensitivity level in response to conductive objects interacting with the electric field within the envelope.
