3.2 Function
MEDUMAT Easy
CPR
is an automatic emergency and transport
ventilator. Highly compressed medical oxygen is used as the
ventilation gas; this is reduced to the necessary operating pressure
via an external pressure reducer. The oxygen is supplied at the
compressed gas connection.
The ventilation parameters – frequency and tidal volume – are
linked together and can be set using the adjusting knob on the
device.
The ventilation gas is transported to the patient through the
ventilation hose via the patient valve and ventilation mask or via
the tube. The lip membrane in the patient valve guarantees that
the expiration gas can be exhaled via the expiration side. In order
to monitor the patient, the device features continuous
measurement of the airway pressure as well as a visual and audible
alarm system.
9 Breathing system filter* Cleans and air-conditions the respiratory air.
10 Instructions for Use Serve to ensure safe use of the device.
11 Tube* Connects the patient to be ventilated with the patient
hose system.

3 Description
The ventilation gas is delivered to the patient via the patient hose
system with patient valve. The patient hose system comprises a
pressure measuring tube (1) and a ventilation hose (2). Both hoses
are connected to the patient valve and the device. The pressure
measuring tube conducts the pressure on the inspiration side to
the device. The pressure measuring tube, ventilation hose, and the
MEDUtrigger cable are connected together with clips (3) in the
disposable hose system. In the reusable hose system, the hose
protection sleeve (3) keeps the pressure measuring tube, the
ventilation hose, and the MEDUtrigger cable together.
The patient valve is designed so that if the device fails,
spontaneous respiration is possible regardless of the ventilation
mode set. If necessary, fresh air can be inhaled via the spontaneous
respiration side with emergency air membrane (4).
The inspiration side (6) serves to enable a breathing system filter, a
ventilation mask or a tube to be attached to the patient valve or to
connect a testing bag to perform a function check. The expiration
side with disk diaphragm (5) serves to discharge the respiratory air
to the environment during expiration and, if necessary, to connect
a PEEP valve to the patient valve.
3.3.2 MEDUtrigger
3-5 MEDUtrigger
The MEDUtrigger serves to trigger individual mechanical breaths
with the set tidal volume. In this way, you determine the respiratory
rate administered yourself. The mechanical breaths are triggered
by actuating the button (3) on the MEDUtrigger.
