The PressureGuard® Protocol’s™ control unit is an efficient one that produces significantly lower levels of noise and heat and uses less energy, in comparison to run-of-the-mill low air loss pumps with high outputs. Caretakers may choose powered floatation or subtle alternating pressure modes of treatment. The auto firm mode enhances surface support to assist with transfers, feeding, and daily living activities, and automatically continues with the chosen mode of treatment 20 minutes later.
