  Anthony HodgeAug 18, 2025
  If the Respironics Medical Equipment impeded oxygen flow indication is activated (Yellow LED illuminates continuously, the Red LED is blinking and the Audible Alarm is beeping), first, remove any items blocking airflow to the device. Then, ensure the flow meter knob isn't completely closed; turn it counterclockwise to center the ball on the prescribed LPM flow. Finally, check the oxygen tubing for kinks or blockages and replace it if necessary.
