Where Should the Flow Meter Ball be on an Oxygen Concentrator?

The flowmeter ball on an oxygen concentrator should typically be positioned within the prescribed flow rate range specified by your healthcare professional. The flowmeter is a part of the oxygen delivery system and is used to control the flow rate of oxygen being delivered to the patient.

Here's how you can determine the appropriate position for the flowmeter ball on an oxygen concentrator:

  • Consult with your healthcare professional: Your healthcare professional will determine the appropriate flow rate for your oxygen therapy based on your specific medical condition and oxygen requirements. They will prescribe a specific flow rate, such as 2 liters per minute (LPM), 4 LPM, etc.
  • Locate the flowmeter: The flowmeter is usually a part of the oxygen delivery system and can be found on the front panel of the oxygen concentrator. It typically consists of a vertical tube with a floating ball inside.
  • Adjust the flow rate: Turn the flowmeter knob or adjust the flow rate control to the prescribed flow rate as directed by your healthcare professional. This will position the ball at the appropriate level within the flowmeter tube.
  • Confirm the position: Once you have adjusted the flow rate, observe the position of the flowmeter ball. It should be floating at or near the prescribed flow rate level. Ensure that the ball is not obstructed or stuck and is freely moving within the tube. Also note there should never be any liquids in your flow meter for any reason. If there is, the most likely cause is a humidifier bottle that is overfull, or has been tipped backwards allowing some water to backflow in to the concentrator.
It's important to note that the specific design and markings on the flowmeter can vary between different models of oxygen concentrators. Some may have numerical markings indicating the flow rate, while others may have different visual indicators. Always refer to the user manual or instructions provided by the manufacturer for your specific oxygen concentrator model to ensure proper usage and interpretation of the flowmeter.
