To purchase an oxygen concentrator, you do need a prescription from your doctor, stating your oxygen level. The U.S. Food & Drug Administration (FDA) makes the rules about prescription sales, and at this time, oxygen concentrators are one of the medical devices for which the FDA requires a prescription. This is to ensure proper care has been taken in selling you an oxygen machine that is appropriate for your needs, and a prescription is the only evidence we have of exactly what those needs are.

The oxygen machine you purchase and use is also largely determined by your prescription, and that&#;s why you may have completely different needs from your friend who also uses supplemental oxygen, even if you both have the respiratory condition. Several important health indicators factor into a prescription for supplemental oxygen that results from a pulse oximetry test and arterial blood gas test.
Some patients who require oxygen therapy only need it when they are exercising, while others only need it while they are sleeping, and others need it for a few hours out of the day no matter what they are doing. Some patients need continuous flow oxygen, while others only need pulse dose. Exactly which type of dosage you need, how many hours out of the day you need it, and at which setting is determined by your doctor.
Your physician will administer tests to find out how much oxygen you require. They will have blood drawn for an ABG test (arterial blood gas) to check your blood gases, as well as use a pulse oximeter to monitor your blood oxygen level. The doctor will also check to see if your blood oxygen levels change drastically during exercise or while you are sleeping. Once your doctor has some measurements relating to blood oxygenation, they can write your prescription for your oxygen requirements.
After you receive your prescription our highly trained Oxygen Specialists will assist you in selecting the correct concentrator that will best suit your needs and lifestyle. For example, if you need a continuous flow of 3 LPM, that only narrows down the available units.
Next, we will discuss how often you will need to use your 3 LPM. Eight hours per day, during the daytime? A few hours during the morning before you leave the house? While you exercise? Only during the night? These other prescribed factors will help you narrow your search down even more.
Your prescription is a formalized way of ensuring your safety. Like all crucial medical information, you want to be sure that in an emergency, the people helping you are aware of your exact physiological need for supplemental oxygen. If you plan an airplane flight, you should notify the airline ahead of time because they may want more than just your prescription; you may be required to give them some extra certification from your physician.
After your doctor has prescribed you oxygen, we encourage you to call us for a free oxygen consultation. We will evaluate your needs and lifestyle and recommend a unit that is ideal for you. Need assistance getting a prescription? Please call us at 877-774-.

To survive, we need oxygen going from our lungs to the cells in our body. Sometimes the amount of oxygen in our blood can fall below normal levels. Asthma, lung cancer, chronic obstructive pulmonary disease (COPD), the flu, and COVID-19 are some of the health issues that may cause oxygen levels to drop. When the levels are too low, we may need to take extra oxygen, known as oxygen therapy.
One way to get extra oxygen into the body is by using an oxygen concentrator. Oxygen concentrators are medical devices required to be sold and used only with a prescription.
You should not use an oxygen concentrator at home unless it has been prescribed by a health care provider. Giving yourself oxygen without talking to a doctor first may do more harm than good. You may end up taking too much or too little oxygen. Deciding to use an oxygen concentrator without a prescription can lead to serious health problems, such as oxygen toxicity caused by receiving too much oxygen. It can also lead to a delay in receiving treatment for serious conditions like COVID-19.
Even though oxygen makes up about 21 percent of the air around us, breathing high concentrations of oxygen may damage your lungs. On the other hand, not getting enough oxygen into the blood, a condition called hypoxia, could damage the heart, brain, and other organs.
Find out if you really need oxygen therapy by checking with your health care provider. If you do, your health care provider can determine how much oxygen you should take and for how long.
Oxygen concentrators take in air from the room and filter out nitrogen. The process provides the higher amounts of oxygen needed for oxygen therapy.
Concentrators may be large and stationary or small and portable. Concentrators are different than tanks or other containers supplying oxygen because they use electrical pumps to concentrate the continuous supply of oxygen that comes from the surrounding air.
You may have seen oxygen concentrators for sale online without a prescription. At this time, the FDA has not approved or cleared any oxygen concentrators to be sold or used without a prescription.
When using an oxygen concentrator:
If you are prescribed an oxygen concentrator for chronic health problems and have changes in your breathing or oxygen levels, or have symptoms of COVID-19, call your health care provider. Do not make changes to the oxygen levels on your own.
Oxygen levels are monitored with a small device called a pulse oximeter, or pulse ox.
Pulse oximeters are usually placed on a fingertip. The devices use beams of light to indirectly measure the level of oxygen in the blood without having to draw a blood sample.
As with any device, there is always a risk of an inaccurate reading. The FDA issued a safety communication in informing patients and health care providers that although pulse oximetry is useful for estimating blood oxygen levels, pulse oximeters have limitations and a risk of inaccuracy under certain circumstances that should be considered. Multiple factors can affect the accuracy of a pulse oximeter reading, such as poor circulation, skin pigmentation, skin thickness, skin temperature, current tobacco use, and use of fingernail polish. Over-the-counter oximeters that you can buy at the store or online do not undergo FDA review and are not intended for medical purposes.
If you are using a pulse oximeter to monitor your oxygen levels at home and are concerned about the reading, contact a health care provider. Do not rely only on a pulse oximeter. It also is important to keep track of your symptoms or how you feel. Contact a health care provider if your symptoms are serious or get worse.
To get the best reading when using a pulse oximeter at home:
Be familiar with other signs of low oxygen levels:
If you experienced a problem or injury that you think may be related to a pulse oximeter or oxygen concentrator, you can voluntarily report it through the FDA&#;s MedWatch program.
