WARNING!
Risk of Injury
To avoid injury from excess oxygen or a deficit of

Do not set the flow above the RED ring. An oxygen flow
greater than 5 L/min will decrease the oxygen concentration.

1. Turn the flowrate knob A to the setting prescribed by your
physician or therapist.
To properly read the flowmeter B, locate the
prescribed flowrate line on the flowmeter. Next, turn
the flow knob until the ball Crises to the line. Now,
center the ball on the L/min line prescribed.
2. If the flowrate on the flowmeter ever falls below 0.5 L/min D for
more than about one minute, the Potential Obstruction Alert
will be triggered. This is a rapid beeping of the audible alarm.
Check your tubing or accessories for blocked or kinked tubing
or a defective humidifier bottle. After rated flow is restored to
between 0.5 L/min and 0.75 L/min, the Potential Obstruction
Alert will turn off.
The use of some accessories such as the
PreciseRx™pediatric flowmeter and the HomeFill
compressor will deactivate the Potential Obstruction
Alert.
