If you’ve been evaluated by your physician and she’s determined you need home oxygen therapy, the Inogen At Home may be just what the doctor ordered. But who benefits most from home oxygen therapy and why choose the Inogen At Home? Let’s explore this further.
Oxygen is a colorless, tasteless, odorless gas and without it, life would not be possible. The air we breathe contains 21% oxygen that when inhaled, flows through our nose to our windpipe and into our lungs. Once in the lungs it passes into the bloodstream where it is carried by red blood cells to all the tissues and organs of our body. Oxygen is needed for metabolism: the conversion of the food we eat into heat and energy.
Some illnesses and conditions cause the heart and/or lungs to work incorrectly, which can lead to your body not getting the oxygen it needs. If your heart or lung function is impaired to such a degree that breathing regular room air isn’t enough to keep your body functioning properly, supplemental oxygen can be used to correct certain oxygen deficits. Generally speaking, folks with low oxygen levels benefit most from supplemental oxygen therapy. Accordingly, the American Thoracic Society recommends long-term oxygen therapy (LTOT) for people with the following results from an arterial blood gas study or from pulse oximetry:
Supplemental oxygen is considered a prescription drug, so you will need a prescription to get it. In order to qualify for home oxygen, your doctor will need to assess that you have a medical need for supplemental oxygen. Arterial blood gas results and pulse oximetry results that indicate low blood oxygen levels, like those listed above, are one part of the qualification process, but there is more to it than just that.
First, your doctor will need to document that you have been diagnosed with an illness or condition that qualifies you for medical oxygen. From there, you will need the arterial blood gas study or pulse oximetry test results indicating that your oxygen levels are too low.
After that, your doctor will be able to write you an oxygen prescription, which will provide the details about what kind of oxygen dosing you need, how often you will need to use supplemental oxygen and how long you will need to use it. Also remember to get a Certificate of Medical Necessity completed by your doctor, along with any other necessary forms for your oxygen provider or your insurance provider. If you are unsure of what you need, contact your oxygen provider for more information.
Your prescription information will help guide you when it is time to purchase your oxygen equipment. Some patients have a diagnosis with special oxygen equipment requirements, like the need for continuous dosing or an oxygen delivery device that is safe to use while sleeping. As such, it is important to make sure you review what you need to look for in oxygen equipment with your doctor. Ultimately, you will have several different options when it comes to oxygen delivery devices.
There are 3 common ways to obtain pure oxygen and store it for home use:
According to the American Lung Association, oxygen has many benefits including:
In addition, oxygen therapy prolongs survival for some patients who use is at least 15 hours a day.
At only 18 pounds and 16.5 inches high, the Inogen At Home is one of the lightest, quietest, most energy-efficient 5 liter home oxygen concentrators on the market today. Compared to other home oxygen concentrators, the Inogen At Home is half the size and far more efficient. In fact, it can literally pay for itself in the long run by saving you money on your electricity bill.
