Starting WarmCloud and self-test
Press for about 2 seconds and ensure that the self-test is starting (includes a test of the over
temperature protection). When successfully completed the unit will begin to inflate the mattress. It
will increase the pressure to 8 to ensure full airflow in the mattress. After 10 seconds air will be let
out and the pressure will be adjusted to 4. Once the pressure 4 is reached the fans and warming
will start. Now you can set the pressure to desired value.
The unit will automatically start at 40°C. It is possible to change temperature as soon as the self-
test is over.
Always stand next to the patient when inflating or deflating the mattress!
Setting temperature
The temperature settings can be changed from 31°C to 42°C by pressing temperature arrow
buttons.

Stop the warming but keep the pressure
Reduce temperature to 30°C and the display will show
“
NO WARMING
”.
This setting is for situations with clamping of blood vessels and shall be done well ahead.
Adjusting the temperature.
After some time at 40 - 42°C, you may need to reduce the temperature when your patient reaches
desired body temperature.
Important:
Always monitor the
patient’s actual temperature with a reliable method.
Pressure selection and adjustment
Pressure can be selected from 1 to 9. Start value is 4. Change pressure with the plus and minus
buttons. Set pressure is shown with a number over the bars.
Pressure value colours on the display:
Black = pressure is being adjusted
Green = Set pressure is reached
Ensure that the patient is no
t “bottoming out”. This will block the airflow and reduce warming
efficiency. Check this by inserting your hand (palm down) between the Mattress and the Operating
table at the heaviest area of your patient; you will feel if there is enough clearance. If required,
increase the pressure by one or two steps.
Important:
Selecting too high mattress pressure may reduce the pressure relieving properties of
the mattress and could cause skin damage.
Stop WarmCloud / Deflating the Mattress
WarmCloud can be stopped in two ways.
1 Press for more than one second. Mattress stays inflated and the unit will go to stand by. You
will manually empty the mattress by carefully opening the Velcro straps.
2 Reduce pressure to 0. Mattress is slowly emptied, and the unit will automatically go to stand by.
Always stand next to the patient when inflating or deflating the mattress.
