About your mattress
The system
OSKA Air Overlay is an overlay system which is
designed to be placed onto an ordinary mattress
or an OSKA underlay. It is designed to be used
for nursing care at home or in a nursing facility
environment.
Application - in regular bed types is possible,
however, preference is given to a patient prole
nursing bed.
The system consists of a control unit featuring a
membrane pump and a bed overlay with 17 air
cells arranged in a transverse manner.The entire
cell unit is equipped with a bi-elastic PU protection
cover.
Recommendations
OSKA Air Overlay system is recommended to
be used for pressure ulcers up to and including
category 2 (medium to high-risk). For higher risk
patients you should use the appropriate system
from OSKA.
Capacity
OSKA Air Overlay system is recommended for
patient weight up to 130kg. Heavier patients are
better accommodated with a more appropriate
OSKA pressure system.
