Oxygen Cylinders

Dear Valued Patient,


At Respocare, our goal is to ensure you have all the information and tools you need to manage your oxygen therapy safely and effectively. Proper management of your oxygen cylinders is crucial for ensuring a steady supply of oxygen when you need it. In this newsletter, we will cover key topics such as how to check your oxygen cylinder levels, use the regulators correctly, and understand how long your oxygen supply will last.


How to Check Your Oxygen Cylinder Levels


Each oxygen cylinder comes with a pressure gauge attached to the regulator, which helps you determine how full the cylinder is. Here’s a step-by-step guide on how to check the levels:


  1. Inspect the Pressure Gauge: Every cylinder is equipped with a gauge that indicates how much oxygen remains in the tank. The gauge usually has color codes:


    • Green: Full

    • Yellow: Low or nearing empty

    • Red: Empty

    The gauge will show a reading in PSI (pounds per square inch). A full cylinder typically shows around 2000 PSI.


  1. Regulator Check: The regulator controls the flow rate of oxygen. Ensure the dial is set to your prescribed oxygen flow rate (e.g., 2 liters per minute). If you're using a continuous flow cylinder, this flow rate will determine how quickly the oxygen is used up.


  1. Calculate How Long Your Oxygen Will Last: It's essential to have an understanding of how long your cylinder will last at your prescribed flow rate. This helps avoid running out of oxygen unexpectedly.


How Long Will Your Cylinder Last?


Let’s calculate how long a 2.8L cylinder will last at a flow rate of 2L per minute. This involves using a simple formula:





  • Cylinder size: 2.8L

  • Pressure: Assume 2000 PSI for a full cylinder

  • Flow rate: 2L/min





So, your cylinder will last approximately 47 minutes at a continuous flow of 2L/min.

Safety Tips for Using Oxygen Cylinders


  • Always store your cylinder upright and secured in a safe place.

  • Regularly check the gauge to ensure you have enough oxygen.

  • Replace your cylinder when it reaches around 500 PSI, to ensure you don’t run out of oxygen.

  • Do not use oil or grease near your oxygen cylinder or regulator.

  • Ensure the regulator is tightly attached to avoid any leaks.


By following these guidelines, you can ensure your oxygen therapy runs smoothly, and you'll have the peace of mind knowing how long your supply will last.
