A patient visualization system having a processor may be communicatively coupled to a pressure sensor device to periodically receive pressure sensor data. The processor may determine a body position according to the pressure sensor data, and associate sensor data to body areas of the subject according to the body position. The associated sensor data may include sensor data indicative of an absence of pressure sensor data associated with one or more of the number of body areas. The processor may track pressure experienced by the body areas of the subject over a period of time to determine a pressure to the body areas over the period of time.
