Understanding Your Oxygen Order Before You Buy a POC

  • Oxygen is prescribed by a control of the flow rate, i.e., liter flow. The common 1-3 liters per minute continuous flow is not appropriate in all situations. This could be too much or not enough.
  • Precision in the use of the proper flow, or amount of oxygen, is necessary. The flow of oxygen should achieve the normal amount of oxygen in your blood, expressed as a saturation above 90%.*

    What to Know Before You Buy a POC

  • Portable Oxygen Concentrators produce oxygen, they do not store oxygen.
  • Portable concentrators produce varying levels of oxygen per minute, which allows for an acceptable dose of oxygen every breath you take.

  • Portable concentrators that weigh 2 to 8 pounds only deliver oxygen on-demand pulse flow. Manufacturers of these devices place arbitrary numbers such as 1-3 or 1-6 to refer to the size of the pulse flow of oxygen and are not the same as liter flow. These settings are considered liter flow equivalents. Also, these devices do not all produce the same amount of oxygen at a given setting.

    Why Self-Monitor Before You Buy a POC

  • Many people commonly check their blood pressure, blood sugar or air flow rate (peak flow) at home. We can measure temperature and weight whenever we have the need.

  • We can now measure our blood oxygen and pulse rate at home as well, using a simple pulse oximeter. A common word used when measuring oxygen is titration.

  • Titrating is the measurement of what your oxygen equipment setting is achieving in the arterial blood. It’s the blood that energizes the tissue. By taking your own measurements, you can adjust your oxygen setting for any situation and with any portable oxygen concentrator.

    Who to Ask Before You Buy a POC

  • We understand that finding a portable oxygen concentrator that accommodates both lifestyle and oxygen needs can be a difficult process for both you and your loved one. Our respiratory team will take the time necessary to choose the right portable concentrator for your respiratory needs.
  • Our trial period on all portable oxygen concentrators assures your oxygen needs are met.
  • * This is a general statement. Your physician must prescribe your specific target saturation level.
