operation of this medical device from a person authorized by WEINMANN Emergency.
2.4 Function
The unit
MEDUMAT Transport is used to treat apnea and to provide respiratory support. By means
of adjustable ventilation parameters, the unit ensures uniform ventilation tailored to the
patient.
Pressure-controlled and volume-controlled ventilation modes can be selected for optimum
patient ventilation.
In CPAP + ASB mode, the unit enables assisted spontaneous breathing with continuous
positive airway pressure and respiration-controlled oxygen inhalation. In addition, the unit
permits O
The unit allows the oxygen concentration of the respiratory gas to be adjusted.
Depending on the version, the unit's large display can show up to three spirometric curves

Hygiene input filter (optional)
For ventilation in a contaminated atmosphere, MEDUMAT Transport can be used with a
hygiene input filter. This protects the device from viral and bacterial contamination.
Inhalation adapter
The ventilation gas can alternatively be supplied to the patient via the inhalation adapter
and the inhalation hose. During inhalation the measuring ports on the device are blocked
by a cover so the device does not take in ambient air.

3. Safety information
Read these instructions for use carefully. It is part of the unit and must be available at all
times.
For your own safety and that of your patients, and in accordance with the requirements of
Directive 93/42/EEC, please observe the following points:
General
• Always carry out a functional check before using the unit
(see "10. Function check" on page 115).
• Please observe the section "9. Hygienic preparation" on page 109 in
order to avoid infection or bacterial contamination.
Warning!
• Risk of injury. Only use MEDUMAT Transport if you are a qualified
medical professional and have received training in respiration
techniques. Improper use may lead to serious physical injury.
• Risk of injury. Never leave the patient or the ventilator unattended during
ventilation. Only then can you respond quickly if the patient's condition
deteriorates or in the event of an alarm or malfunction. Delayed response
on the part of medical personnel may lead to serious physical injury.
• Risk of injury from deactivated alarm LED, deactivated acoustic alarm
output and darkened display in NVG mode!

Safe handling of oxygen
Warning!
• Risk of explosion! In combination with combustible substances (grease,
oil, alcohol etc.), highly compressed oxygen may give rise to spontaneous
explosive reactions.
• Risk of fire! If only the O2/AIR inlet/outlet is used, close the O2/AIR inlet
on the side with a suitable cap. Otherwise, gas will escape from the O2/
AIR inlet on the side.
• Risk of poisoning! Highly concentrated oxygen can have a toxic effect on
the patient if administered for too long and depending on the age of the
patient. When ventilating with pure oxygen or an oxygen-air mixture,
make sure that oxygen is only administered for an appropriate period.
• Keep the units and all screwed unions absolutely free from oil and
grease.
• Be sure to wash your hands before working on the oxygen supply.
• Smoking and open flames are strictly prohibited in the vicinity of fittings
containing oxygen.
Caution!
• When assembling the unit, and when changing cylinders, tighten all
screwed unions on the oxygen cylinder and pressure reducer by hand
only. Never use tools. Overtightening damages the threads and seals,
resulting in leaks.
• Secure the oxygen cylinders so that they cannot fall over. If a cylinder falls
on the pressure reducer or valve, these could break off, causing a violent
explosion.
• Risk of insufficient oxygen supply! Two oxygen sources can be connected
to this unit simultaneously. Make sure that only one oxygen source is
open at any given time and that there is no gas reflux. Otherwise, one of
the oxygen sources may empty itself unnoticed. Sufficient oxygen supply
to the patient can then no longer be guaranteed when the unit is in use.
• Always open the cylinder valve slowly to prevent pressure hammer on the
fittings.
• Do not empty oxygen cylinders completely, as this may allow moist
ambient air to enter and cause corrosion.
26 EN Safety information
Ventilation/Handling
Caution!
• The USB port on the device must only be used for the application scenarios
outlined in the instructions for use. Only USB sticks which conform to the
USB standard 2.0 should be inserted in the USB port, otherwise this
interferes with operation of the unit, putting the patient at risk.
• Patient and ventilator must be kept under continuous observation during
ventilation.
• Prolonged ventilation can lead to atrophy of the muscles (dependency of
the patient on ventilation).
• Prolonged ventilation may lead to the airway drying out. Ensure
adequate conditioning of the respiratory gas.
• Only apply high ventilation pressures for short periods and only if
medically indicated. Permanently applied high ventilation pressures can
be injurious to the patient.
• Make sure that the patient valve is not covered or its function impaired,
e.g. by the patient's position.
• The patient hose systems for the device have different dead spaces.
Please take the dead space into consideration when selecting the
ventilation parameters, particularly when ventilating infants with very
small tidal volumes. Otherwise, there is a risk of insufficient ventilation.
• Do not place the patient valve of the disposable hose system with
reduced dead space near the O2/Air inlet of the MEDUMAT Transport,
in order to prevent the device sucking in CO
• Please note that the inspiratory resistance of a disposable hose system
with reduced dead space increases during adult ventilation.
• Please note that the use of additional accessories between the ventilation
hose and patient (e.g., humidifiers, nebulizers, and goosenecks) increases the dead space.
• The device is not suitable for the ventilation of premature babies (born
before the end of the 36th week of pregnancy).
• Please note that if concentrator oxygen with an oxygen concentration
outside of the specifications is used (see 14.1, page 142), the tolerances
specified for the O
measurement may also vary.

• Risk of injury from switching on a device with activated NVG mode
during daylight or without a night vision device!
A device with activated NVG mode cannot be used straight away during
daylight or without a night vision device. This can injure the patient.
– Keep an alternative ventilation unit at the ready.

4. Installation
As a rule, MEDUMAT Transport only has to be installed for stationary use in rescue vehicles,
helicopters or aircraft. In this case, fastening sets can be supplied as accessories.
If MEDUMAT Transport is supplied complete on a portable system, the unit is ready for
operation and no further installation work is required. There are separate instructions for
use for the portable systems.
Warning!
After installation, you must perform a functional check (see "10. Function check" on
page 115) to ensure reliable operation.
4.1 Connecting oxygen cylinder
Warning!
• Risk of explosion! Wash your hands thoroughly before doing any work
on the oxygen supply. Hydrocarbon compounds (e.g. oil, grease,
cleaning alcohol, hand cream or adhesive plasters) can cause explosive
reactions if they come into contact with highly compressed oxygen.
• Never use wrenches or other tools to tighten or unscrew the union nuts.
Notice:
Only use the High Flow OXYWAY Fast II and OXYWAY Fix III pressure reducers on the
MEDUMAT Transport. Foreign pressure reducers can impair the unit's efficiency.
Removing the empty cylinder
1. Close the valve on the oxygen cylinder.
2. Switch MEDUMAT Transport off again.
3. Undo the screwed union at the cylinder by hand.
30 EN Installation
Switch on MEDUMAT Transport at the On/Standby/Off
switch. This allows the remaining oxygen to escape and
the unit is pressure-free. Only when the contents gauge
on the pressure reducer indicates 0 bar, can the
screwed union be undone by hand.
