Frequently Asked Questions

Medical-grade oxygen is treated as a medication, and just like any other medication, your doctor must prescribe it with specific instructions regarding how much to use and how often.
A prescription typically includes the following information:

  • Specifics about oxygen usage/frequency
  • Recommended dosage (liters per minute)
  • Defined delivery device
  • Continuous v Pulse Dose
  • Doctors’ contact information

Pulse dose delivery is based on receiving a bolus of oxygen when breathing and inhaling, whereas Continuous Flow Oxygen is delivered at a continuous rate regardless of the patient’s breathing. Most POCs provide Pulse Dose, but some provide both (Pulse Dose and Continuous Flow). Which is right for you is based on a number of factors including your daily routines, physician recommendations, and lifestyle goals.

The Federal Aviation Administration (FAA) ruled that all passengers who require oxygen must be allowed to bring FAA-approved POCs on all U.S. aircraft with more than 19 seats. Foreign airlines must also allow portable oxygen concentrators on all flights to and from U.S soil. All OxygenDirect POCs are FAA approved, which means you can safely take with you when flying.

Oxygen concentrators vary in many ways. We can help you compare dosage settings, sizes, and features to determine which concentrators are best for your unique situation.

Research shows using oxygen significantly improves patients’ quality of life and the benefits are usually immediate. Patients have more energy, an increase in overall brain health and functions, and a renewed sense of freedom.

A possible downside to oxygen therapy is that some users experience a bit of dryness in their nose or sinuses from receiving oxygen. Patients find they need to experiment with several types of cannulas (the tube device placed in the nostrils to deliver supplemental oxygen) or skin gels in order to achieve the ideal setup. Fortunately, recent innovations in cannula technology now allow for a softer, cushioned, and more comfortable fit than ever before.

A common myth is that oxygen is addictive and by using supplemental oxygen, you will become more dependent upon it and subsequently weaken your natural ability to process oxygen. This is simply not true. Using supplemental oxygen will allow the natural processes in your body to work more efficiently, decrease excess strain, and increase your overall health.


“OxygenDirect was excellent. I had some questions which they answered quickly and helped me place a correct order. Product was delivered quickly (2-days) and all additional supplies were exactly what I wanted. Pricing was great and I obtained my supplies at a fraction of the cost I was quoted by the durable supply company I had been using.”
