O2 % (O2 Flush) (LTV® 1000 Only)
The O
2
% (O
2
Flush) button is a dual function control (O
2
% and O
2
Flush).
• When being used to set the percentage of oxygen delivered by the ventilator through the oxygen
blending system (O
2
%), push and release the O
2
% (O
2
Flush) button, as described below.
• When being used to elevate the delivered FIO
2
to 100% for a preset period of time (O
2
Flush),
push
and hold the O
2
% (O
2
Flush) button for 3 seconds, as described in Chapter 10 - Extended
Features, O2 Flush.
The O2% control establishes the percentage of oxygen to be delivered through the oxygen blending
system. Oxygen blending requires a high pressure oxygen source and is active only when Low
Pressure O
2
Source is not selected
20
. When Low Pressure O
2
Source is selected, this control is
displayed as dashes “---” and may not be modified.
To set the percentage of oxygen delivered by the ventilator:
1) Push and release
the O
2
% (O
2
Flush) button.
2) Change the setting using the Set Value knob.
Range: 21 - 100 %
WARNING
Inspired Oxygen (FIO
2
) Concentration – If the patient has a variable respiratory rate, his/her minute
ventilation will fluctuate. If exact concentrations of inspired oxygen (FIO
2
) are required to be delivered
to the patient, it is recommended that an accurate oxygen analyzer with alarms be used.
AVERTISSEMENT
Concentration d’oxygène inspiré (FIO
2
) – Si la fréquence respiratoire du patient est variable, sa
ventilation-minute va fluctuer. Lorsqu’une concentration exacte d’oxygène inspiré (FIO
2
) est
nécessaire pour une transmission au patient, il est recommandé d’utiliser un analyseur de niveau
d’oxygène
2
précis, comportant des alarmes.
CAUTION
Oxygen Supply Contamination - The accuracy of the oxygen delivery capabilities of LTV
®
ventilators can be compromised by foreign debris contamination in the oxygen supply system. To
reduce the risk of airborne contaminants entering the ventilator, ensure that any oxygen supply
connected to the ventilator is clean, properly filtered
21
and that the ventilator’s O2 Inlet Port Cap is
securely installed on the O2 Inlet Port whenever the ventilator is not connected to an external oxygen
supply.

In addition to the existing internal O
2
Inlet filter, P/N 14313, an External, In-Line Oxygen Filter (P/N 14470) is
available from Pulmonetic Systems, Inc.
