Air Fluidized Bed Vs Low Air Loss

Calculation of healing rates using the largest ulcer from each resident found mean healing rates greatest for air.

Air fluidized bed vs low air loss.

A laser is used to cut very small holes on the top side of the mattress body which enables air to flow all over the surface. The ahrq guideline which hill rom cites also states that a clean pressure ulcer should show evidence of some healing within 2 to 4 weeks. A low air loss mattress is a mattress designed to prevent and treat pressure wounds. A low air loss mattress is essentially an air mattress covered in thousands of tiny holes.

The mattress is composed of multiple inflatable air tubes that alternately inflate and deflate mimicking the movement of a patient shifting in bed or being rotated by a caregiver never leaving the patient in one position for any extended length of time. An air fluidized support surface employs the circulation of filtered air through silicone coated ceramic beads creating the characteristics of fluid. Other reports of decreased pressure have ranged from 5 mm hg to16 mm hg for air fluidized therapy while low air loss beds reduced pressures to 12 mm hg to 45 mm hg. Low air loss means that the surface provides flow of air to help manage the microclimate of the patient s skin.

Low air loss mattress design. 39 in one study interface pressures on a standard hospital bed ranged from 44 mm hg sacrum to 104 mm hg heel. Air fluidized beds are therapy beds that provide an ideal healing environment for patients with compromised skin. These mattresses also have an electric air pump usually positioned at the foot of the bed that continuously flows new fresh air into the mattress.

Check the box which describes coexisting conditions which may affect wound healing specify condition s. An air fluidized bed supports the body with thousands of tiny soda lime glass beads suspended by. A randomized controlled trial will be required to compare low air loss bed and air fluidized bed therapy we are not aware of such a published study. They are designed to minimize the forces that cause tissue breakdown including pressure shear friction heat and moisture.

Low air loss mattresses are made using laser technology. A blower will typically output around 100 150 liters of air into the mattress drying the skin. These holes are designed to let air out of the mattress extremely slowly. Form ms 80 must be signed and dated by the physician.

If coexisting conditions are present list the condition s physician signature and date. Support surfaces were categorized as. Air fluidized surfaces are expensive and difficult to maintain. Need for air fluidized low air loss bed coexisting condition s.
