    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.

    (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.
  • Page 15 • Smoking and open flames are strictly prohibited in the vicinity of all fittings containing or trans- porting oxygen. • During assembly and when changing oxygen bottles only hand-tighten screwed connections to the bottle and the pressure reducer. Never use tools for this purpose.

  • Page 17: Installation

    4. Installation Permanent mounting is usually necessary only when MEDUMAT Easy CPR is installed as a fixture in rescue vehicles, helicopters or aircraft. If MEDUMAT Easy CPR is supplied complete on a carrying platform or in an emergency rucksack, it is ready for use and requires no further installation.

  • 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.

  • Page 22: Using The Ventilator

    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.

  • Page 23: Selecting The Ventilation Settings

    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.

  • Page 24: Performing Ventilation

    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.

  • Page 25: Monitoring Ventilation

    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.

  • Page 26: Ventilation With Peep Valve

    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.

  • Page 28: Cpr Mode

    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).

  • Page 30: Terminating Ventilation Or Demandflow

    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.
  • Page 33 < 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.
