Use the graphs in Figure 3-15. and Figure 3-16. for estimating the liter flow of supplemental
oxygen needed to attain a particular O
2
percentage. Note that the first graph applies when PEEP
is on (and NIV off) and the second graph applies when PEEP is off. The graphs are also printed on
the instructions for use that are packaged with the reservoir.
To keep a constant percentage of O
2
, the flow meter will need readjustment when PEEP is turned
on or off, the bias flow setting is changed (PEEP and NIV on), or the patient’s minute volume
changes.
Use a calibrated oxygen monitor with alarms (such as the one that is built-in to the ventilator) to
assure that the percent of O
2
that is delivered by the ventilator into the patient circuit matches
the prescribed value.

WARNING:
Using an oxygen concentrator in place of medical-grade oxygen will result in lower oxygen
percentage levels than what is printed on the graphs. Use a calibrated oxygen monitor to verify
the level of oxygen enrichment.

Caution:
Water in the oxygen supply can cause equipment malfunction and damage.

DC Auto Lighter Power Adapter
The DC auto lighter power adapter (part number ADP3203P) is used to plug the ventilator into
any vehicle’s DC power outlet (12 V DC to 16 V DC). The external DC source of power will not only
power the ventilator but also charge both batteries in the internal dual battery system.
This cable can also be used to connect the ventilator to other external batteries (12 V DC to 16 V
DC) when combined with an alligator clip adapter that is available from common consumer elec-
tronics retailers.
To use the DC auto lighter power adapter, insert the adapter’s pinch-release power plug into the
external power supply input located on the lower left corner of the Power Pac battery pack.
Ensure that the cord is to the right of the plug and that it locks in place securely. Plug the other
end of the adapter into a vehicle autolighter power outlet (12 V DC to 16 V DC).
To remove the DC auto lighter power adapter from the external power supply input, gently pinch
the connector to release the locking pin and then pull the plug out.
