Start ventilation

Use presets and work according to guidelines
By using the setting option of the Vt/kg body weight (BW) 4-10 ml/kg BW to be
applied, you will be working according to guidelines and determining the calculated
tidal volume for volume-controlled ventilation.
The ideal body weight and thus also the tidal volume to be applied are calculated
differently for male and female patients. The following formulas are used for this
purpose:
iGajic, O. et al. Ventilator-associated lung injury in patients without acute lung injury at the onset
of mechanical ventilation. Critical care medicine, 2004, no. 32, p. 1817-1824.

iiiDevine, Ben J. Gentamicin therapy. The Annals of Pharmacotherapy.
1974, 8. year, no. 11, p. 650-655
With a male patient 185 cm tall and a setting of 6 ml/kg BW, this results in the
following tidal volume:
The tidal volume results accordingly:
Vt = 80 kg x 6 ml/kg KG = 480 ml
= 79.51 kg ~ 80 kgIBW (in kg) = 50 + 2.3 x 185
2.54 - 60
IBW female (in kg) = 45 + 2.3 x Height in cm
2.54

-60
IBW male (in kg) = 50 + 2.3 x Height in cm
2.54

-60
Start faster and ventilate more precisely
From now on you don't have to think long about which tidal volume (Vt) is best for
your patient. With MEDUMAT Standard
2
, you can now initiate ventilation even more
precisely and quickly. By entering the patient’s height and gender, your ventilator
automatically calculates all ventilation parameters for the ideal body weight (IBW).
The IBW serves as an important indicator for setting the ventilation parameters
i
.
MEDUMAT Standard
2
enables you to start ventilation more quickly and far more
precisely – giving you more time for all the other important tasks.
Start ventilation by height

NIV therapy
Switch on ventilator.
1
Select “New patient” in the start
menu.
2
Set the patient’s height and gender or
select the appropriate patient group:
Adult, Child, Infant.
3

Select the desired CPAP therapy using
the navigation button: PEEP, pMax,
ΔpASB. After adjusting the values,
begin the ventilation via “start”.
5
Now connect the patient to MEDUMAT
Standard². It is possible to adjust the
values using the navigation button
while the ventilation is running. You
can nd other ventilation parameters in
the user menu on the right navigation
button. If it is necessary to switch the
ventilation mode, this is done using the
“user menu” function button on the
right side.
6
Select one of the following ventilation
modes: CPAP* or CPAP + ASB (if
available).
*pure CPAP is the ventilation form CPAP
+ ASB with a ΔpASB of 0mbar

Inspiratory trigger
The inspiratory trigger triggers a pressure support or a mechanical breath as soon
as inhalation effort is detected.
Trigger level Corresponding unit value
Level 1 (sensitive) Approx. 3l/min
Level 2 (medium) Approx. 6 l/min
Level 3 (insensitive) Approx. 10 l/min

Pressure
support and the
expiration trigger
Pressure support ΔpASB
The pressure support is always given as a value above PEEP. In addition to the set
PEEP, a patient receives this as soon as the inspiration trigger has been detected.
Example calculation:
PEEP = 5mbar, ΔpASB = 10mbar inspiration pressure in the inhalation phase = 15mbar
Trigger level Corresponding unit value
Level 1 (long) Approx. 10% Flow max
Level 2 (medium) Approx. 35 % Flow max
Level 3 (Short) Approx. 70 % Flow max
Expiratory trigger
Initiate expiration as soon as the ow to the patient is only the set value (in %) with
respect to the maximum ow. The length of the pressure support is set with the
expiratory trigger.
Trigger sensitivity: 5-80% of max. ow. In principle, the following applies: the smaller
the % value, the longer the pressure support lasts.

Pressure ramp (pressure increase time)
A pressure ramp (or the pressure increase time) denes the time in which the pressure
increases from the PEEP to the inspiration pressure. This pressure increase time can
be set by the shape of the ramp: at, medium and steep.

Resuscitation (CPR) with IPPV
Switch on the device.
Press the CPR button and select the
patient group.
Check the ventilation parameters. In
the ventilation phase of 30:2 or 15:2
resuscitation, press the mask with the
“Double C grip” over the patient’s
mouth and nose.
Then hold down the MEDUtrigger key
until two mechanical breaths have been
administered.

Following successful intubation, switch
to continuous ventilation “CPR IPPV”.
Check the ventilation parameters.
During the cardiac rhythm analysis or
debrillation, select “pause” to pause
the ventilation.
• No movement artifacts
• Reduction of thoracic impedance
• No oxygen enrichment of ambient air
Following successful debrillation, if
applicable, press “pause” again to
restart the ventilation. The ventilation
will start automatically after at most
50seconds.
Once ROSC is achieved, press the CPR
key again to exit the CPR mode. Then
check the ventilation parameters and
select, if applicable, the Air Mix key to
lower the FiO2 to <1.0.

Resuscitation(CPR)withCCSV

Press the CPR button and select the
patient group
Check the ventilation parameters. In
the ventilation phase of 30:2 or 15:2
resuscitation, press the mask with the
“Double C grip” over the patient’s
mouth and nose.
Then hold down the MEDUtrigger key
until two mechanical breaths have been
administered.

Following successful intubation, switch
to continuous ventilation “CPR CCSV”.
Perform chest compressions continu-
ously. MEDUMAT Standard² will deliver
a mechanical breath synchronously to
each compression.
You can use the frequency tachometer
shown above to determine the frequen-
cy of the compressions.
5
6
If a chest compression device is brought
to the patient, this must be indicated via
the middle navigation button.
With machine compressions the com-
pression frequency alarm is deactivated
and the frequency tachometer turns
gray.
The triggers are optimized by the device
and the trigger level is automatically set
to "3".

In the absence of chest compressions,
the hands-off time is displayed. When
the alarm limit is reached, the device
outputs a hands-off time alarm. If this
is not answered with compressions, the
device automatically switches to "CPR
IPPV” ventilation.
If chest compressions are detected
again by MEDUMAT Standard² during
"CPR IPPV”apnea ventilation, the de-
vice automatically switches back to
"CPR CCSV".
If these two measures do not lead to
success, CCSV is not applicable to this
patient. Please switch to "CPR IPPV" via
the right navigation button.

If less or no compressions are detected
by MEDUMAT Standard² despite cor-
rectly performed compressions, please
perform the following escalation steps:
• Reduce the set trigger
• Increase the set PEEP

Anesthesia induction (RSI)
Switch on the device
Select “New patient” on the home
screen and set the patient’s height
and gender. Or select the appropriate
patient group: Adult, Child, Infant
Select “RSI” in the “mode” submenu
MEDUMAT Standard² begins the
therapy in demand mode. In this mode,
the spontaneously breathing patient is
pre-oxygenated. The total RSI time and
the time since the last spontaneous
breath are shown on the display.
