2.3 Ventilation function MEDUMAT Easy CPR operates within a pressure range of 2.7 to 6 bar and at a flow rate of not less than 70 l/min O . It has a built-in power pack.
2.4 Demandflow function The Demandflow setting switches the Demandflow setting MEDUMAT Easy CPR breathing-controlled O inha- lation. Such inhalation must be carried out with the respiration mask. A small inspiration (trigger-) pulse causes oxygen to continue flowing until slight over- pressure interrupts the flow.
2.6 Audio response The device has an audio response facility that can be switched on for user guidance, especially for users who have little practice. If audio response is not required, a key combination can be used to switch it off (see “5.11 Audio re- sponse for user guidance”...
(see “7.4 Checking patient hose system” on page 50). Note • Do not use the MEDUMAT Easy CPR in toxic en- vironments or where there is a risk of explosion. • MEDUMAT Easy CPR is not suitable for hyper- baric use (pressure chamber).
Page 14
To prevent infection or bacterial contamination, please observe section “6. Hygiene preparation” on page 42. • MEDUMAT Easy CPR should be used only by medically qualified personnel who have had training in ventilation techniques. Severe physi- cal damage may be caused by incorrect use.

connecting or disconnecting it. The connection socket may be damaged if the MEDUtrigger connector is rotated. 2. Slide the pressure gauge tube onto connection. 3. Slide the ventilation hose onto connection. C P R Make sure that this does not cause any kinks in the pressure gauge tube already connected.
Page 20
if the patient is intubated, attach the patient valve to the tube. Filter If a filter is to be used, this should be installed be- tween the patient side connector on the patient valve and the mask or tube. In this case, the MEDUtrigger is attached to the filter.
4.3 Wall mounting set A wall mounting set (see “10.2 Accessories” on page 66) is available for permanent fixing, e.g. on a vertical surface inside a vehicle. Please refer to the sheet enclosed with the wall mounting set for details of dimensions and installa- tion procedure.
3. Select the desired ventilation settings (see “5.2 Selecting the ventilation settings” on page 23). 4. Switch on the MEDUMAT Easy CPR with ON/ OFF switch. The ventilator will then run a self- test lasting approx. 2 seconds.
Otherwise an alarm is sounded. The MEDUMAT Easy CPR will then start to func- tion with the selected ventilation settings. 5.2 Selecting the ventilation settings We recommend selecting the ventilation settings be- fore switching on, to prevent unnecessary waste of oxygen.
45 mbar”) If the maximum ventilation pressure is reached, e.g. in cases where compliance is inadequate, MEDUMAT Easy CPR sets off a stenosis alarm (see “Stenosis alarm” on page 31). Note: The mask/tube switch can only be operated when the ventilator is switched on.
Intubation The patient will normally be intubated before the tube is connected to the patient valve. Risk of injury from the tube moving! The MEDUtrigger on the patient valve may move the tube and injure the patient. Detach the MEDUtrigger from the patient valve before putting the patient valve on the tube.
If lung compliance diminishes during ventilation, the ventilator will react by increasing the ventilation pressure at constant volume. Example of ventilation sequence before and after compliance diminishes 5.5 Ventilation with PEEP valve A PEEP valve can be fitted to the expiration tube on the patient valve with an adapter.
Demandflow mode! Demandflow must be switched on for O inhalation. To switch the MEDUMAT Easy CPR to Demandflow mode, turn the ventilation settings regulator knob until it engages in the fixed point marked by the white triangle. The green LED indicates that it is Freq.(min...
5.8 CPR mode Automatic ventilation with the selected frequency is stopped when CPR mode is activated. With the help of MEDUtrigger, you can trigger single respiratory strokes with the selected tidal volume. This enables you to choose the respiratory frequency adminis- tered yourself.
Page 29
(see “5.11 Audio response for user guidance” on page 34 and “5.12 Switching the metronome on and off” on page 38). This makes particular sense if the MEDUMAT Easy CPR is being used with other devices that have audio responses and/or a metronome (e.g. AED).
This prevents entry of moist atmospheric air that can cause corrosion. 3. Switch off MEDUMAT Easy CPR. To prevent the ventilator being switched off unintentionally, ON/ OFF switch must be kept pressed down for at least 2 seconds until the LEDs in the alarm panel light CP R up.
Page 31
“ डवाइस म खराबी है ! वै क ि पक व टले श न दान कर” (“Device malfunction! Administer alternative ventilation!”). In this case you must not use the MEDUMAT Easy CPR. The failure alarm can be confirmed by pressing the ON/ OFF switch. The patient valve is designed to enable spontaneous CP R breathing in the event of equipment failure.
Page 32
If the maximum ventilation pressure is exceeded for a second time during the same inspiration phase, the unit finally switches to expiration and vents the pa- tient tube system completely. The next inspiration begins with the following ventilation stroke accord- ing to the frequency selected.

< 2.7 bar O alarm Oxygen pressure at the pressure connection to the MEDUMAT Easy CPR has dropped to less than 2.7 bar. The reason is usually an almost empty oxygen cylinder. In this case, MEDUMAT Easy CPR can no longer function correctly because the operating parameters are no longer within the permissible limits.
The ventilator must be switched off before the battery can be changed (see “Changing the main battery” on page 63). Cancelling acoustic alarm If there is an alarm, you can temporarily cancel the acoustic alarm by pressing the alarm mute button: Stenosis: 30 seconds Disconnection:...
