Why'd do I need a prescription for an oxygen concentrator?

In accordance with the US Food & Drug Administration (FDA), oxygen concentrators are considered a Class II Medical Device. This means that you must have a valid prescription from a board-certified doctor in order to purchase one.

Why Do You Need a Prescription for an Oxygen Concentrator?

The FDA seeks to ensure that oxygen supplies, including oxygen concentrators, are being properly distributed to patients with genuine medical need. Patients who receive prescriptions include those with asthma, pneumonia, respiratory distress syndrome or chronic obstructive pulmonary disease (COPD).

How Do You Get an RX for an Oxygen Concentrator?

Talk to your doctor if you think you may need a prescription for an oxygen concentrator. If necessary, your doctor will perform tests to evaluate your blood oxygen levels. Your doctor may even test to see if blood oxygen levels change during exercise or sleep.

One of the most common tests is called an ABG test, or arterial blood gas. This requires the physician to draw blood and test blood gases.

Who Gives You a Prescription for an Oxygen Concentrator?

With the results of these tests, your doctor will write a prescription defining your oxygen level needs. These needs include the dosage of oxygen, often written in liters per minute (LPM). Some physicians will include the type of concentrator they feel is best – a portable oxygen concentrator or a home/stationary unit. They will also indicate how often you require oxygen therapy (daily, during exercise, while sleeping, etc.).

Along with your primary care physician, a pulmonologist may also write a prescription for oxygen therapy.

Choosing an Oxygen Concentrator Based on Your Prescription

Your prescription will make it easier to select the best oxygen concentrator for your needs. Here is an explanation of the guidelines provided in your prescription.

Continuous Flow or Pulse Dose

There are two types of oxygen delivery when it comes to oxygen concentrators: continuous flow and pulse dose. Continuous flow means that you require a constant, steady supply of oxygen and will most likely need a home/stationary oxygen concentrator. If your prescription calls for pulse dose oxygen, your needs are likely less severe. Pulse dose oxygen is delivered in short bursts, triggered by a patient’s inhalation. Portable oxygen concentrators are best suited for pulse dose oxygen needs.

Flow Settings

Your prescription will also define specific oxygen level needs. If you are prescribed a continuous flow oxygen concentrator, your prescription will assign how much oxygen per minute you will need. Be sure the machine you select has the capacity your prescription requires. 

The same applies for a pulse flow oxygen concentrator. Look for a machine that has the capacity of the pulse setting prescribed. It is important to note that a prescription of 2 LPM is not the same as a prescription for a pulse setting of 2. Consult with your doctor to determine what pulse setting best matches your continuous flow setting. Do not change settings without first talking to your doctor.

Oxygen therapy benefits people with respiratory illnesses in several ways, including:

  • Helping patients continue living active lifestyles
  • Increasing oxygen flow while sleeping at night
  • Increasing oxygen flow while exercising

What Should Be Included In Your Oxygen Therapy Prescription?

  • Diagnosis: This will explain why you are now required to receive oxygen therapy, commonly due to varying respiratory illnesses.
  • Oxygen flow rate (liters per minute): Oxygen flow rate is the amount of oxygen a patient receives from an oxygen concentrator. This is measured in liters per minute (LPM). Doctors usually prescribe a flow rate of 1-10 LPM. 
  • Duration and frequency of use: This is the number of hours you need to receive oxygen therapy per day. If your doctor prescribes continuous oxygen therapy, this means that you should be using your oxygen concentrator for at least 15 hours each day. 
  • Type of oxygen delivery device (e.g., nasal cannula, mask): There are a range of oxygen delivery devices to manage your respiratory condition. These include oxygen tanks or portable and at-home oxygen concentrators. Oxygen  can then be received using a face mask or nasal cannula.

Your prescription will also define specific oxygen level needs. If you are prescribed a continuous-flow oxygen concentrator, your prescription will assign how much oxygen per minute you will need. Be sure the machine you select has the capacity your prescription requires. 

The same applies to a pulse flow oxygen concentrator. Look for a machine that has the capacity of the pulse setting prescribed. It is important to note that a prescription of 2 LPM is not the same as a prescription for a pulse setting of 2. Consult with your doctor to determine what pulse setting best matches your continuous flow setting. Do not change settings without first talking to your doctor.

How Much Does It Cost To Get A Prescription?

The cost of getting a prescription varies depending on factors like the type of medication, your insurance coverage, and where you get it filled. Without insurance, expect to pay anywhere from $10 to $200 or more for a prescription.
