HIGH O

PRES (LTV® 1000 Only)
When the average oxygen inlet pressure exceeds the acceptable limit for the type of oxygen source,
the HIGH O2 PRES alarm is generated.
• If Low Pressure O
2
Source is selected, the inlet pressure is >10 PSIG.
• If Low Pressure O
2
Source is not selected and the oxygen concentration is set to greater than
21%, the inlet pressure is >85 PSIG.
When the Low Pressure O
2
Source option is selected and a high O
2
pressure source is attached to
the ventilator, an Automatic High O
2
Switch Over safety response generates a HIGH O2 PRES alarm,
switches the ventilator to High Pressure O
2
Source mode and sets the percentage of oxygen to be
delivered in the gas flow to 21%.
When a HIGH O2 PRES alarm occurs:
• The HIGH O2 PRES message is flashed in the display window.
• The O
2
% (O
2
Flush) control display is flashed.
• The audible alarm is sounded.
To reset the HIGH O2 PRES alarm:
1) Push the Silence / Reset button to silence the alarm.
2) Adjust the oxygen inlet pressure.
3) Push the Silence / Reset button to reset the alarm.
This alarm is not available in NPPV mode.
