摘要:
A method for detecting occupant position change on a support surface includes establishing a rate of change of pressure in a head end test zone and in a foot end test zone, comparing the head end rate to at least one head end rate limit, comparing the foot end rate to at least one foot end rate limit, and inferring, in response to the comparing steps, whether or not occupant migration has occurred. An associated occupant support includes a frame and a mattress. The mattress includes head and foot zones each having at least one pressurizable bladder. The support also includes a controller adapted to compare a head end pressure change to a head end change limit, to compare a foot end pressure change to a foot end change limit, and to infer, in response to the comparing steps, whether or not occupant migration has occurred.

According to the present disclosure, a patient support apparatus includes a mattress having an air bladder system configured to sense pressure levels along the mattress surface and perform unloading of mattress areas corresponding to specific patient body areas to relief loading to the area, and to perform unloading independently or in combination with lateral rotation. The air bladder system may include a support bladder system and a rotation bladder system.

A method for monitoring an environment for a patient on a patient support device can include: receiving a temperature reading from a wireless sensor coupled to a body of the patient; comparing the temperature reading to air flowing through an airflow system associated with the patient support device; and modifying the air flowing through the airflow system.

摘要:
An occupant support (20) includes an intermediate layer (26, 30, 120) and a wicking layer (52) atop the intermediate layer. The wicking layer comprises a first region (62) having a lower moisture wick rate (W1) and a second region (64) having a higher wick rate (W2). A moisture management cover (52) for use with an occupant support article has discrete higher (64) and lower (62) wick rate regions. A related method for transporting moisture away from a target region of an occupant support comprises distributing the moisture over an area beyond area A and exposing the distributed moisture to a fluid stream capable of receiving the moisture.
