General recommendation: You should seek instruction on the correct handling, use and
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

22 EN Description
Patient Hose System
The ventilation gas is supplied to the patient via the Patient Hose System, comprising the
ventilation hose and all leads necessary for comprehensive ventilation and monitoring.
The Patient Hose System is designed to permit spontaneous respiration even if the
MEDUMAT Transport malfunctions.
The following versions of the patient hose system are available:
• Reusable hose system with CO
• Reusable hose system without CO
• Disposable hose system with CO

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!
The alarms are barely perceptible as a result of the deactivated alarm
LED, the deactivated acoustic alarm output and the darkened display in

Safety information EN 25
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.

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.
Connecting a new cylinder
1. Briefly open the valve of the new oxygen cylinder, then shut it again. This is to blow
away any particles of dust.
Caution!
• Make sure that the patient is not connected up to the MEDUMAT
Transport when you are establishing the gas supply. Otherwise, the
unit's automatic self-test can lead to incorrect results.
• When doing this, hold the valve opening away from your body in such a
way that any flying particles cannot injure yourself or other people!
2. Screw the pressure reducer to the cylinder valve using
the knurled union nut. Tighten the union nut by hand.
3. Screw the pressure hose onto the outlet of the pressure
reducer (if not already connected) using the G 3/8
union nut.
4. Screw the other end of the pressure hose to the
compressed gas connection of the MEDUMAT
Transport (if not already connected).
Connecting a second oxygen source
Caution!
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.
If desired or if foreseen in your establishment, you can connect a second oxygen source,
e.g., an oxygen cylinder or a CGC to the O2/AIR inlet/outlet (quick connector to the front
of the unit).
Notice:

5.7 Selecting additional ventilation functions
The ventilation functions "O2 concentration" and "100% O2" are available for all the
ventilation modes. You can call up and set these functions at any time using the fixedassignment function buttons on the right of the display.
Warning!
Risk of poisoning! Highly concentrated oxygen can have a toxic effect on the patient
if administered for too long, 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.
Setting the O2 concentration
To save oxygen, ventilation is normally carried out with an oxygen/air mixture. The
administered oxygen concentration can be selected between 40% and 100%. The
currently measured value is shown in the info field on the display.

route of the hose system, depending on the patient's position.
50 EN Operation
Caution!
Example of ventilation progress before and
after decrease in compliance during volume-controlled
ventilation
Using the elbow increases the dead space of the hose system. Take this into account
when setting the ventilation parameters. Otherwise the success of treatment may be
compromised.
2. Attach the mask to the hose system.
3. If necessary, introduce a Guedel oropharyngeal tube to keep the patient's airways free.
4. Place the ventilation mask over the patient's mouth and nose.
5. Tilt back the patient's head and, at the same time, hold the mask tight against the
patient's face with the C grip.
5.9 Monitoring ventilation
General
During ventilation, you must monitor the patient continuously. You can follow the progress
of ventilation on the display. You can select various display formats.
High airway resistances, e.g., due to obstructions of the airway or during external cardiac
massage, may change the respiratory minute volume, depending on the ventilation mode.
If lung compliance decreases, the unit responds as follows:
• With volume-controlled ventilation, the ventilation pressure rises until
the set pressure limit is reached, while the ventilation volume remains
constant. Then the applied volume drops.
• With pressure-contolled ventilation, the applied volume drops while the
pressure remains constant.
Notice:
All the displayed measurements for flow, volume, or MV relate to ambient
temperature and ambient air pressure.
Operation EN 51

You can use the alarm mute button at any time to mute
the alarm signal for 120 s. During this time, the yellow LED
of the alarm mute button flashes. Pressing the button
again reactivates the acoustic alarm. The visual alarm
continues to remain active.
Visual and acoustic alarms are reset automatically as soon
as the cause of the alarm has been removed.
Operation EN 55
Notice
• Following the start of ventilation, all alarms are
automatically muted for 120 seconds. This is with
the exception of the technical alarms "Supply
pressure < 2.7 bar", "Battery almost empty", and
"Device malfunction", which cannot be muted.
During this time, visual alarms are still displayed.
• The acoustic alarm output is permanently muted in
NVG mode.
5.12 Ventilation with breathing system filters (not supplied with the unit)
For hygiene purposes, and to condition the air for breathing, you can equip the patient valve
with commercially available filters (HME, bacterial or combined HME/bacterial filters) with
standard 15/22 mm connections. This increases both inspiratory and expiratory resistance.
Therefore you should monitor the ventilation pressure and volume with special care.
Allowance must be made for the larger dead space, especially with children.
Always follow the filter manufacturer's instructions for use.
5.13 Ending ventilation
Caution!
Never empty the oxygen cylinder completely. Always ensure that there is a certain
residual pressure in the cylinder when you return it for filling, since this prevents
moist ambient air from entering and causing corrosion.
1. Check the remaining oxygen content on the contents gauge of the pressure reducer. If
the contents gauge indicates 50 bar or less, the cylinder must be refilled or a reserve
cylinder obtained to ensure that the unit remains ready for use.
2. Close the valve on the oxygen cylinder.
3. Hold down the On/Standby/Off button for 2 seconds to
switch the unit to standby.
Notice:
The unit still uses up electricity in standby mode. If the unit does not need to be used
for a long time or is not connected to the power supply, we recommend switching
it off completely. To do so, hold down the On/Standby/Off button until the LED alarm
goes out (approx. 10 seconds).

1. Have the fully charged battery ready to hand.
2. Press and hold the On/Standby/Off button until the alarm LED goes out (approx.
10seconds). The device is now switched off.
Caution!
Do not remove the battery whilst the device is in operation, as this prevents the
settings for the last patient being safely stored. Always switch off the device first.
3. Pull the low battery currently in use out of the unit's battery compartment.
4. Insert the replacement battery into the compartment until you hear an audible click.
5. Switch on the device.
6. To adopt the settings entered before changing the battery: Click on "Previous patient"
in the Start menu to call up the settings.

MEDUMAT Transport has an internal power supply with a rechargeable battery.
Two battery versions are available:
• BATTERY pack Plus WM 28385 for internal and external charging; can be
recharged either in the unit or using an external power supply unit
WM 28937; charge level can be checked on the battery.
• BATTERY pack WM 28384 for internal charging; can only be recharged
in the unit; charge level can be checked on the battery.
For recharging the battery, an external DC power supply with 12 – 15 V (internal charging)
or 15 V (external charging) is required. Use only the vehicle/aircraft on-board electrical
power supply or, if charging from the mains, use power supply unit WM 28937.
MEDUMAT Transport can be operated from an external power supply when the battery is
empty. The battery is charged while the unit is in operation but charging takes longer than
when the unit is switched off.
Caution!
• Never operate the unit without a battery because any voltage dips in the
power supply cannot then be bridged. This would mean that
uninterrupted ventilation of the patient could not be guaranteed.
• Battery-operated medical devices have a limited operating period.
MEDUMAT Transport can normally be operated for 7.5 hours (see "14.1
Specifications" on page 142) without an external power supply,
provided that the battery is fully charged. You should therefore ensure
that the battery is always as fully charged as possible, or that you have a
spare battery ready for use.

Operation EN 61
Ending battery charging
MEDUMAT Transport automatically determines the optimum point at which to end
charging by measuring and evaluating the charging curve and battery temperature. As
soon as charging has ended, the charging indicator glows green continuously.
Interrupting battery charging
Battery charging is continuously monitored by MEDUMAT Transport.
Faults which cause charging to be interrupted are:
• Battery temperature rises above 45°C, e.g., due to high ambient
temperature, or falls below +5°C
• Charging current is too high (>3 A) e.g., due to a short-circuit
If one of these problems occurs, charging is automatically interrupted and the charging
indicator glows red.
Charging is also interrupted if there is no external power supply, e.g., because the unit,
which is mounted on a portable system, is removed from the wall mounting. The charging
indicator does not light up in this case because this is not a fault, but a normal operating
situation. As soon as the external power is restored, e.g., when the portable system is put
back into the wall mounting, charging continues immediately.

The aPVC mode is used for pressure-controlled, assisted ventilation at a fixed mandatory
ventilation rate.
In case of spontaneous respiration, the patient has the possibility of increasing the rate and
consequently the minute volume MV. If the patient displays a spontaneous respiratory effort within a specified time slot of the expiration, the mandatory mechanical breath is synchronized with the patient's respiration. The time slot or trigger time slot can be set in %
of Te before the next expected mandatory mechanical breath. If the patient displays a
spontaneous respiratory effort outside of the set trigger time slot, no mandatory mechanical breath is triggered.

The CPAP + ASB mode can be separated into its individual elements:
The set value CPAP/PEEP is used to increase the pressure level of respiration in order to raise
the functional residual capacity (FRC) of a spontaneously breathing patient.
The ASB mode is used for pressure support of insufficient or exhausted spontaneous
respiration. The patient is able to breathe spontaneously without any restriction, but is
supported in his breathing effort by MEDUMAT Transport.
The CPAP + ASB mode is used exclusively on patients with adequate spontaneous
respiration.
In principle, the pressure is set at the end of expiration (PEEP). In addition, pressure support
(
Δ pASB) can be switched on if needed. Ventilation can be individually adjusted to suit the
patient with the aid of the inspiratory and expiratory triggers. The inspiratory trigger
indicates a sensitivity for triggering pressure support. The expiratory trigger determines
when the unit should switch off pressure support, which enables the administered volume
and the inspiration time to be set indirectly.
The set maximum pressure limitation (pMax) ensures the safety of the patient.

The controlled ventilation mode PRVC + ASB combines the advantages of both pressurecontrolled ventilation and volume-controlled ventilation. The set tidal volume is applied
with the minimum ventilation pressure possible.
Ventilation begins with three volume-controlled breaths with the set tidal volume and
decreasing flow. The volume-controlled breaths have a plateau time of 50% of the
configured inspiration time T
. The unit selects the measured plateau pressure as starting
i
value for the inspiratory pressure pInsp of the following pressure-controlled ventilation. It
measures the administered volumes and adjusts the ventilation pressure accordingly. If the
lung parameters change during ventilation, the unit alters the inspiratory pressure pInsp in
increments of a maximum of 3 mbar in order to achieve the set tidal volume again and
thereby automatically compensate for changes in the patient.
Measuring the applied volume is improved by compensating hose compliance. This enables
precise control of the required tidal volume, in particular of small tidal volumes under high
airway pressures.
The set maximum pressure limitation (pMax) ensures the safety of the patient. For safety
reasons inspiratory pressure pInsp
(pMax). Once maximum ventilation pressure (pMax - 5 mbar) is achieved, the unit
administers as much volume as possible. If this volume deviates from the set tidal volume,
is 5 mbar below the set maximum pressure limitation
the unit triggers the low-priority alarm "Vt not achievable".

parameters" in the main menu (see "7.4 Advanced ventilation parameters" on page 87).
The S-IPPV mode is used for volume-controlled ventilation with a variable mandatory
minute volume MV. Throughout the entire expiratory phase, a trigger is active which
enables the patient to trigger a new breath. This means the patient has the option of
increasing the respiratory rate and therefore the minute volume MV, and adapting these
to his/her needs. As a rule this mode is used on patients who have inadequate spontaneous
respiration.
Ventilation in the S-IPPV mode corresponds to ventilation in the IPPV mode with the
difference that it is possible to synchronize ventilation with the patient's efforts to inhale.
Since the setting for the respiratory rate is lower, the patient can trigger mandatory
mechanical breaths spontaneously. A trigger time slot extending throughout the expiration
time is available for this synchronization.

7.1 Activating automatic alarm limits
General
When the "Activate automatic alarm limits" function is
activated, the unit automatically determines limits for the
alarms relating to respiratory physiology. Alternatively, you
can activate the automatic alarm limits by keeping the
alarm mute button depressed (approx. 2 seconds).
Crucial for determining the limits are the respiratory values
measured at the moment when the function is activated
(Vt
, MVe, f, if necessary etCO2).
e
In the "Alarm Limits" menu (see "7.2 Alarm Limits" on
page 85), you can set the amount of deviation (in %) from
the current respiratory value, which should trigger an
alarm.
84 EN Main menu
Notice:
This overwrites the values set in "Alarm Limits" (see
"7.2 Alarm Limits" on page 85).
Automatic alarm calculation for the Apnea alarm
Depending on the set percentage, the Apnea alarm is set to 4 (10%), 5 (20%) or 6 (30%)
respiratory periods. The length of a respiratory period is 60/f in seconds, i.e., with a
measured respiratory rate of, for example, 15/min, the increments for the Apnea alarm
limit are 16 s, 20 s, and 24 s.
7.2 Alarm Limits
You can set limit values for alarms relating to respiratory
