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 concentrator 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, need it only when they are exercising, while others need it only while they are sleeping, and others need it for a few hours in a day no matter what they are doing. Some patients need a continuous flow of oxygen, while others need a pulse dose. Exactly which type of dosage you require, how many hours out of the day, 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 test) 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.
Selecting the Correct Concentrator
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 (liters per minute), 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.
