Correlation Between Pressure Differences and Micro-vascularization Changes in Bedridden Paraplegic Patient

A capacitive pressure mapping device (XSensor) is set up on the patient air mattress bed. It records the interface pressure on the whole patient body with one frame every second during one hour. Then the file is saved and the pressure mapping device is removed from the patient hospital bedroom.

A medical device called O2C, measuring micro-vascularization related parameters (oxygen saturation, hemoglobin quantity and blood flow) is used. The probe (= an optic fibre) is set up lightly on the patient skin or on a transparent adhesive for 1 minute. The median value of the local micro-vascularization parameters are saved on the O2C interface. The location of the measurement is chosen using the pressure mapping device to locate peak pressure area. Then the O2C is removed from the patient hospital bedroom.
