How To Read Oxygen Concentrator Gauge

Oxygen Gauge


Oxygen concentrators are life-saving devices that are used to provide oxygen to people who have difficulty breathing. These machines work by extracting oxygen from the air and delivering it to the patient through a nasal cannula. One of the most important components of an oxygen concentrator is the gauge. The gauge provides important information about the flow of oxygen and the concentration of oxygen in the air. In this article, we will discuss how to read the oxygen concentrator gauge.

Step 1: Understand the Gauge

The gauge on an oxygen concentrator is typically located on the front of the machine. It consists of two parts: the flow meter and the oxygen concentration indicator. The flow meter is used to measure the flow of oxygen in liters per minute (LPM). The oxygen concentration indicator shows the percentage of oxygen in the air.

Step 2: Check the Flow Meter

To read the flow meter, locate the indicator on the gauge that indicates flow rate. It is usually a small ball that moves up and down in a clear tube. The ball will rise and fall as the flow of oxygen changes. The number on the gauge closest to the ball indicates the flow rate in LPM.

Step 3: Check the Oxygen Concentration Indicator

To read the oxygen concentration indicator, locate the percentage indicator on the gauge. The indicator will typically show a range of percentages, from 21% (the normal concentration of oxygen in the air) to 100%. The number closest to the indicator shows the current percentage of oxygen in the air.

Step 4: Monitor the Gauge

It is important to monitor the gauge regularly to ensure that the oxygen concentrator is working correctly. If the flow rate or oxygen concentration falls outside the normal range, it may indicate a problem with the machine. In this case, it is important to contact a healthcare professional immediately.

Tips for Using an Oxygen Concentrator

– Always follow the manufacturer’s instructions when using an oxygen concentrator. – Keep the machine clean and free from dust and debris. – Check the nasal cannula regularly for signs of wear or damage. – Never smoke or use any open flames near the oxygen concentrator. – Keep the oxygen concentrator away from sources of heat, such as radiators or direct sunlight.


Reading the oxygen concentrator gauge is an important part of using the machine. By understanding how to read the gauge, you can ensure that you are receiving the correct flow rate and concentration of oxygen. Remember to monitor the gauge regularly and follow the manufacturer’s instructions for safe and effective use of the oxygen concentrator.
