USE AND OPERATION
6.2.2
FUNCTION TEST
The unit performs a function test after being switched
on. Watch during the test to see whether the indicators
behave as described below:
• A short audible alarm indicates that the unit is
ready for a possible mains failure alarm.
The unit now checks its own safety devices::
• Temperatures (3) and (6) on the display (11) read
.
• The red fault indicator (4) comes on.
• The audible alarm sounds.
• The display (11) shows FUNCTION TEST.
If the function test is successful, the display shows the
message FUNCTION TEST OK and the unit automatically
starts normal operation.
This test lasts a few seconds.
WARNINg If the function test is not successful,
the unit is not safe for operation.
The unit cannot be operated if:
• No beep indicating the mains
failure alarm sounds after the unit
is switched on.
• The automatic function test
switches the unit off automatical-
ly because it detects a fault in its
own safety devices.
• One or more indicators are faulty.
In these cases, have the unit checked by
a Medos-approved customer service.
6.2.3
SETTINg THE TEMPERATURE
• Use the two arrow keys (14)
and (16) to set the target value
for the water temperature. The
temperature can be adjusted
in increments of 0.1 °C from 15
to 39 °C.
• The temperature display (6)
shows the set target value.
• For target temperature values
above 38 °C, press and hold
the Confirm button (15) while
pressing the arrow key (14) at
the same time.
• For target temperature values
below 35 °C, press and hold
the Confirm button (15) while
pressing the arrow key (16) at
the same time.
WARNINg
• A considerable amount of heat will
be removed from the patient’s blood
at a temperature below 35 °C.
• A considerable amount of heat will
be added to the patient’s blood at a
temperature above 38 °C
The addition or removal of heat by the Medos oxygenator
to/from the patient’s blood only occurs if the temperature
of the water in the oxygenator is higher or lower that the
patient’s blood temperature.
The amount of heat transfer is directly proportional to the
temperature difference between the blood and the water
in the oxygenator.
