Flowrate - Invacare Perfecto2 Series User Manual

Flowrate

NOTE: For this procedure, refer to FIGURE 6.5.
NOTE: Take care not to set the flow above RED ring. An oxygen flow
greater than 5 L/min will decrease the oxygen concentration.
1. Turn the flowrate knob to the setting prescribed by your
physician or therapist.
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.
