As soon as Vamos is connected to AC line power, it will start
charging the internal battery. For this, the monitor does not
need to be switched on.
If the battery is charged during operation of the Vamos monitor
a battery symbol and arrow are shown in the field for the
battery status to indicate the charging.
When the battery is completely discharged, the charging time
to a full charge is typically 10 hours.
If the battery is completely charged the symbol disappears.
With a fully charged battery, Vamos can be used for 1.5 hours
without AC power.
During operation with the internal battery (without AC power)
the power supply indicator light shows yellow and the ad isory
message "Power fail!" appears.
A battery symbol together with the remaining capacity of the
battery is shown in the field for the battery status.
33 % (Example)
If the internal battery is completely discharged, the screen
display will disappear and the power failure alarm will sound.
If the battery is discharged to a le el below 10 % the following
caution message appears:
Batt. low !!

Connecting the Sample Line
Sample Gas Scavenging
Connecting the Sample Line
1Screw the filter into the T-piece.
2Plug the T-piece into the patient connection of the Y-piece
– with the filter on top to prevent it becoming clogged with
liquid.
3Screw the sample line firmly to the filter and water trap.
4Instead of the separate T-piece and filter, a Y-piece with
direct connection port for the sample line may also be used.
Sample Gas Scavenging
●Use hose 11 90 520, see Ordering Information on
page 49.
●Connect the hose to the exhaust port » « on the back of
the monitor.
Push the other end of the exhaust hose into the anesthetic
gas scavenging hose.
Secure against disconnection.
The hose of the anesthetic gas scavenging line should have
an inner diameter measuring at least twice that of
hose 11 90 520 (i.e., at least 0.55 inches, 14 mm).
NOTE: The sample gas taken from the Y-piece reduces the
tidalvolume.
W RNING !
Leaks in the pneumatic system can lead to wrong gas
measurement values.
W RNING !
Dräger cannot warrant or endorse the safe performance
of third party gas sample lines for use with the Vamos
monitor. We recommend using genuine Dräger OEM
sample line. Other lines may alter the technical data of
the monitor.

Operating Instructions Vamos, 1. US ed.
Switching On
Vamos initially displays the selection menu for the volatile
anesthetic agents and prompts the user to select the
anesthetic agent used.
The previously selected anesthetic agent is marked with an
arrow (example: jHal).
●Turn dial knob to select the anesthetic agent you are using.
Press dial knob to confirm.
If you wish to measure a previously selected anesthetic agent
again:
●Simply press dial knob to confirm.
If Vamos has been switched off for less than 3 minutes it
automatically switches to measurement mode after the start-up
and test routines. In this case the » « key does not have to be
pressed. Vamos starts measurement with all parameters set as
before it was switched off.
The CO2 concentration is represented as a breath by breath
real-time waveform.
Below this waveform, the following numeric values are
displayed:
— Inspiratory concentration of the volatile anesthetic agent
used,
— End-tidal concentration of the volatile anesthetic agent
used,
— Inspiratory N2O concentration FiN2O,
— End-tidal N2O concentration FetN2O,
— Inspiratory CO2 concentration FiCO2 ,
— End-tidal CO2 concentration FetCO2.
To change to other units of measurement for CO2 and a
different scale for the real-time waveform, see “Selecting CO2
Unit of Measurement/CO2 Scale” on page 26.
W RNING !
The Vamos monitor cannot automatically recognize the
anesthetic agent used. The respective anesthetic agent
must always be set manually.
Otherwise, incorrect measurements will result.
W RNING !
The Vamos monitor cannot recognize anesthetic gas
mixtures. Consequently, measurements will be incorrect
if more than one anesthetic agent are present of one
time!
