This non-randomized clinical study will compare pressure injuries and the change in pressure injuries for subjects who are placed on the Freedom Bed compared to those placed on a standard Group II Low Air Loss/Alternating Pressure Mattress in the Ventilator Unit at Northeast Center for Rehabilitation and Brain Injury. Additionally, the incidence of pneumonia, urinary tract infections, circulatory performance, sleep deprivation and caregiver self-perception on performance will be monitored and documented.

Detailed Description: This study will include 9 ventilator or oxygen dependent subjects with comparable diagnoses, nutritional levels and Stage III and/or IV pressure injuries. Of the subjects selected, 5 subjects will be placed on Freedom Beds and 4 will be placed on Group II Low Air Loss/Alternating Pressure Mattresses for a period not less than 6 months. A waiver of informed consent is required prior to bed placement and data collection. Consented subjects will have primary and secondary diagnosis recorded, pressure injuries photographed and classified, assessment of ventilator/oxygen support measured, oxygenation levels, nutrition levels, and estimated cardiac condition. Subjects will receive daily treatment and wound care as prescribed by the attending physician with weekly measurements and reporting of values. Subjects will continue until they reach one of the study endpoints: 1) discharge from the ventilator unit, or 2) withdrawal of informed consent, or 3) completion of the 6-month study.

Subjects placed on Freedom Beds will be automatically turned in accordance with positions determined optimal and approved by the attending physician. All programmable turning angles, dwell times, head and leg elevations must be "dialed in" within a week of the study beginning. Any modification to the program during the study must be approved by the care team and documented accordingly.

Subjects placed on Group II Low Air Loss/Alternating Pressure Mattresses will require manual repositioning every 2 hours. All turning and/or repositioning must be timed and documented.

The primary and secondary outcome measures documented on each subject throughout the week will be collected by the Clinical Research Coordinator (CRC) on a weekly basis and submitted to the Principal Investigator. The weekly reports will then be consolidated by the CRC into a monthly report and submitted to the Institutional Review Board (IRB), Principal Investigators (PI) and Supervising Authorities (SA) for review.
