The mattress is now in the
filling phase while the LED
"Low Pressure" is lit.
Adjust the weight* of
the patient (lying down)
using the weight scale* on the device. When the "Low
Pressure" LED goes out and the "Normal Pressure" LED
comes on, the patient can be placed on the system.
If a patient is to sit in bed for a short period of time, the
pressure in the cells must be increased. You can use the
outer blue weight scale* as a guide for this.
Important! The Med Aire DuoWave is not suitable for
long periods of sitting!
*The weight adjustment scale indicated is a guideline
and does not reflect the actual pressure in the air
chambers.
Hand check
After each change in pressure and position, use your
hand to check the proper pressure setting at the
buttocks/hips. When correctly adjusted, a hand should
be able to be easily inserted between the patient and a
deflated cell.

Alternating pressure function
All air chambers are evenly inflated and deflated in
a 1:1 ratio. An alternating cycle involves in each case
the inflating and deflating of an air chamber and takes
approx. 10 minutes. The first 3 air chambers in the head
area remain static.
Static function
The Med Aire DuoWave has a static function as a
standard feature.
This is switched on using the "Static" button. The LED
indicates that the static function is enabled.
The air chambers all maintain the same pressure and
ensure adjustable pressure-relief positioning.
In static pressure-relief mode, the deepest point on the
patient (buttock/hip area) should sink into the system
to approximately halfway down the upper cell system
(approx. 3-4 cm).
Note: Perform a hand check to verify; see hand check
section.
Air flow
The Med Aire DuoWave has nine air flow cells. This group
of air chambers is microperforated at the edge and in this
way, it ensures that the Med Aire DuoWave is actively
supplied with air.
CPR (cardiopulmonary resuscitation)
Before resuscitation can/may be performed on the
system, the system must be fully deflated.
For rapid deflation, pull down on the red tab printed
with "CPR" at the head
end (see fig.). The tab is
on the same side as the
hose system. The valves
open and air escapes
from all of the cells.
To supply the system
with air once again, close
the CPR valve again by pressing it firmly and securely
fasten the tab marked "CPR" once again.
