A person support apparatus can be adjusted to support a person in a number of different positions, including a laying-down position, a seated position, and positions intermediate the laying-down and seated positions. One or more sensors, which may be carried by, worn by or attached to the person, the person support apparatus, or another device, can be used to detect physiological responses of the person. A computing device, such as a bed controller, can generate an indication of the persons state based on one or more of the sensor inputs. The computing device can, based on the patient sate indication, cause an adjustment to the position or configuration of the person support apparatus to occur.
