130 EN MEDUVENT Standard
WM 67851 01/2021
10 Description of the modes
Manual mode is used to support cardiopulmonary resuscitation
(according to the resuscitation guidelines), rapid sequence
induction (RSI) or manual ventilation in place of a bag-valve mask.
In the ventilation phase, mechanical breaths are administered at a
defined volume and pressure limit (manually) using the trigger
button of the MEDUtrigger. In this process, the I:E ratio is always
1: 1. PEEP is 0 mbar and cannot be adjusted. The set pressure limit
(pMax) ensures the safety of the patient. The basis for calculating
the value of O
2
to be supplied is the algorithm 30: 2. (In this case,
2 mechanical breaths are administered in quick succession with a
subsequent pause in ventilation).
For dispensing the maximum possible oxygen concentration in the
inspiratory gas (O
2
i) during resuscitation, a supply value is shown
on the display. This value depends on the tidal volume, and
indicates how much oxygen is to be supplied to the device.
If Manual mode is used to administer a regular frequency, we
recommend basing the oxygen concentration setting on the MVi
displayed.

Time
In order to achieve the shortest-possible hands-off time during
resuscitation, during CPR 30: 2, keep the MEDUtrigger depressed
during the ventilation pause until two inspirations have been
delivered.
Press the trigger button again to trigger up to another 2
mechanical breaths.
