Air Fluidized Bed Vs Low Air Loss

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.

Air fluidized bed vs low air loss.

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. Group 1 static overlays and replacement mattresses group 2 low air loss beds alternating pressure and powered non powered overlays mattresses and group 3 air fluidized beds. Need for air fluidized low air loss bed coexisting condition s. An air fluidized bed supports the body with thousands of tiny soda lime glass beads suspended by.

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. Air fluidized surfaces provide pressure redistribution by immersion and envelopment using a fluid like medium created by forcing air through silicone beads. 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. Powered and air fluidized beds are semi electric or completely electric hospital support surfaces with a fully integrated powered mattress that has a total height of 3 inches or greater and a surface designed to reduce friction and shear.

Low air loss mattress design. Air fluidized surfaces are expensive and difficult to maintain. Low air loss means that the surface provides flow of air to help manage the microclimate of the patient s skin. Check the box which describes coexisting conditions which may affect wound healing specify condition s.

Form ms 80 must be signed and dated by the physician. They are designed to minimize the forces that cause tissue breakdown including pressure shear friction heat and moisture. 39 in one study interface pressures on a standard hospital bed ranged from 44 mm hg sacrum to 104 mm hg heel. A low air loss mattress is essentially an air mattress covered in thousands of tiny holes.

Low air loss mattresses are made using laser technology. Air fluidized beds are therapy beds that provide an ideal healing environment for patients with compromised skin. Support surfaces were categorized as. A low air loss mattress is a mattress designed to prevent and treat pressure wounds.

These holes are designed to let air out of the mattress extremely slowly. A blower will typically output around 100 150 liters of air into the mattress drying the skin. An air fluidized support surface employs the circulation of filtered air through silicone coated ceramic beads creating the characteristics of fluid. 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.
