Flowrate
NOTE: For this procedure, refer to FIGURE 5.5 on page 19.
1. Turn the flowrate knob to the setting prescribed by your
physician or therapist.
 CAUTION
Never set the flow greater than 5 L/min.
 WARNING
DO NOT change the L/min setting on the flowmeter unless a
change has been prescribed by your physician or therapist.
NOTE: To properly read the flowmeter, locate the prescribed flowrate
line on the flowmeter. Next, turn the flow knob until the ball rises to
the line. Now, center the ball on the L/min line prescribed.
NOTE: A Potential Obstruction Alert indicates a condition that
may be associated with a partial or complete obstruction of oxygen
output.
2. If the flowrate on the flowmeter ever falls below 0.5 L/min
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 between 0.5 L/min and 0.75
L/min, the Potential Obstruction Alert will turn off.
NOTE: The use of some accessories such as the PreciseRx™
pediatric flowmeter and the HomeFill compressor will deactivate the
Potential Obstruction Alert.
