6.2.4 Setting the temperature
•
Set the nominal value for the water temperature - i.e. the
temperature on the contact area between water pad and
patient - with the two arrow keys (19) and (21). The
temperature can be set in steps of 0.1 °C between
15 and 39 °C. The temperature display (14) shows the set
nominal value.
•
For nominal temperature values above 38 °C, press the up
arrow key (19) and the release key (20) at the same time.
•
For nominal temperature values below 35 °C, press the arrow
key (21) and the release key (20) at the same time.
► Temperature below 35 °C, withdraw heat from the patient at a
higher rate.
► Temperatures above 38 °C supply the patient with heat at a
higher rate.
► Places of the body, which are subjected to increased
pressure, may suffer under pressure necrosis and/or burns,
even at temperatures below 40 °C. This applies for long-term
applications and risk patients in particular
For the indication and safe operation application, the
chapters 4.2.1; 5.4.2, 6.2.8 and 6.2.9 are to be observed!
External conditions and pad size influence the desired nominal
value; e.g. very high or low nominal values at high or low ambient
temperatures possibly may not be reached and/or when
connecting a large pad or two water pads. In this case, set a
lower or higher nominal value so the unit can safely regulate the
temperature.
Check the water flow on the display (15)!
