Function Check
Hazardous therapy if device connected to patient during function check!
If the device is connected to the patient during the function check, this might lead to
therapy posing a risk as a result of excessively high pressures or unsuitable ventilation
volumes. This might expose the patient to the risk of serious or life-threatening injury.
Always disconnect the device from the patient for the function check.
Perform a function check at the following intervals:
Part Interval
Device • Before each use
• After each hygienic reprocessing
• After each repair
Breathing circuit • Before each use
• After each hygienic reprocessing
• After each repair

Preparing for the function check
1. Check battery status: The rechargeable battery must be fully charged.
If necessary: Charge rechargeable battery.
2. Check the following parts for external damage:
- Device
- Labels on the device
- Connectors and cables
- Breathing circuit
- Accessories
3. If necessary: Replace damaged parts.
4. Check the patient valve of the reusable breathing circuit.
5. If necessary: Replace the breathing circuit.
6. Checkthellleveloftheoxygencylinder.
7. If necessary: Replace the oxygen cylinder.
Performing a function check
You can perform the function check with the following test lungs:
• Testing bag WM 1453
• Testing bag WM 1454
• EasyLung for WEINMANN Emergency WM 28625
Requirement
• The device is disconnected from the patient.
• The rechargeable battery is fully charged.
• There is an SD card in the SD card slot.
• Thehygienelterisinsertedintheltercompartment.
• The oxygen supply is shut off.
• The function check has been prepared.
• The device is switched on.

4. If you want to test the oxygen supply:
Select “Yes”.
or
If you do not want to test the oxygen
supply: Select “No”.
The device skips the oxygen test
(steps 5 to 8 are skipped).
1. Select the “Function check” menu
item.
2. Prepare the device:
• Connect the breathing circuit to the
device.
• Connect the test lung to the
breathing circuit.
• Connect MEDUtrigger.
3. Select “Start”.
Follow the on-screen instructions.

5. Set the oxygen supply rate
(5-15 l/min).
6. Select “Start”.
9. If an alarm tone sounds: Select
“Yes”.
8. Select “Next”.
7. Stop the oxygen supply and close the
oxygen cylinder. This test item can be
skipped if no oxygen source is available.

14.Ifyouhavereplacedthehygienelter:Select“Reset”.
Color Action
Green Continuetousehygienelter.
Yellow Keephygieneltertohandororder

Red Replacehygienelter.
11. Press all the controls except the On/
Off button one after another.
12. If the MEDUtrigger is not displayed
in the function check: Activate
MEDUtrigger in the Operator menu and
repeat the function check.
13.Proceedwiththehygienelterin
accordance with the following table:
10.IfthealarmLEDashesred:Select
“Yes”.

17. Select “Finish”.
18. Switch off the device.
19. Take the test lung off the breathing circuit.
16. The status report appears
(example: Function check passed).
15.Enterthelterresetcodespecied
in the Operator menu. On delivery, the
lterresetcodeis“0000”.
Select “OK”.
Proceed with the device in accordance with the following table:

Start up more quickly and ventilate more accurately
From now on, you no longer need to spend time considering which tidal volume and
which respiratory rate (Vt) is best suited to your patient. With MEDUVENT Standard,
you can now start ventilation even more accurately and quickly. When you enter the
patient’s height and gender, your ventilator automatically calculates all the ventilation
parameters via ideal body weight (IBW). IBW is an important indicator for setting
ventilation parametersi.
Ventilation Start-Up Based
on Height
iGajic, O. et al. Ventilator-associated lung injury in patients without acute lung injury at the onset
of mechanical ventilation. Critical Care Medicine, 2004, No. 32, p. 1817-1824.
Risk of injury resulting from incorrectly set limitation of maximum airway pressure!
An excessively high airway pressure might expose the patient to serious or life-
threatening injury.
Always set the pressure limit pMax to suit the current patient and the current
therapy.

3. Enter patient’s gender and height and
select ventilation mode.
4.Conrmwith“Next”.
5. The device shows a preview of the
ventilation parameters calculated. If
necessary: Adjust ventilation parame-
ters. Select “Start”.
6. The device shows current ventilation
parameters.
2. Select “New patient”.1. Switch on ventilator.

Using presets and working within guidelines
In the Start menu, you can set the patient's height under the “New patient” menu
item. This section explains how the ventilator automatically calculates the ideal tidal
volume using height and gender.
Ideal body weight (IBW) is calculated from stated height (X) as shown below:
Example
IBW (female) = 45 kg + 2.3 kg • x
2.54 cm -60
• Child(1) (height < 154 cm):
IBW child = 2.05 kg • exp x
50 cm
IBW (male) = 50 kg + 2.3 kg • x
2.54 cm -60
• Adult(2) (height > 154 cm):
The tidal volume for the patient is calculated with the aid of ideal body weight and
the setting Vt per body weight (Vt/body weight) in the Operator menu:
• Patient, male, height 185 cm
Vt = IBW • Vt
body weight
• Setting for Vt/body weight = 6 ml/kg
