Most of my 30 years as a respiratory therapist have been at homecare. Homecare is unique in that you are now in a patient’s territory. You must respect not only their property but also their beliefs on medical treatments. No matter how ill, to accept treatment or not is still the patient’s choice. And patients often do not know about treatments.
Oxygen therapy is one of the most misunderstood home therapies. I have heard a lot of my patients express their concerns over its use. Here I will try to address some of the knowledge gaps as well as misconceptions and myths that have persisted for decades.
First is the very little-known fact that oxygen is a drug. Any amount of oxygen above the 20.9% level that is in our air needs a doctor’s prescription. Oxygen administered to a patient as “supplemental oxygen” is designed to bring the patient’s oxygen level up to the normal range.
In a hospital, rehab center, or doctor’s office, the patient’s provider will establish how much “supplemental oxygen” is needed to regulate oxygen levels in the bloodstream and whether a patient needs oxygen at rest, with exertion, or while sleeping. The patient must use it as prescribed to avoid exacerbation of symptoms and to stay alive and healthy.
I have had long conversations with many patients trying to explain “why” they need to use the oxygen as prescribed and how it is necessary to help the brain and heart function. Most are not aware that oxygen is regulated by the FDA and is considered a “drug”, nor are they aware of what can happen to the body due to oxygen deprivation or over-utilization. A simple anatomy lesson and some education go a long way; and so does having a trusted provider to explain it.
So, because oxygen is a drug, it does matter if you stop treatment, change liter flows or use liberally. Any of these practices without MD permission can be deadly.
Second, the myth that oxygen will spontaneously combust or explode in the house. Oxygen does not have any properties that would allow it to explode like a bomb. However, it is true that oxygen is a hazardous material if used inappropriately, like near an open flame.
If you remember the “ fire triangle”, three basic things are needed to start a fire...fuel, oxygen, and a spark. Oxygen will not spontaneously combust, but it will accelerate a flame or existing fire. Oxygen systems used in the home must be stored correctly. They must not be near heat registers, never in a closed closet, car trunk, or small space, and if in aluminum tanks, must be lying down and tucked under a bed or dresser.
Another big myth associated with oxygen therapy is that oxygen is addictive, that once the patient starts, they will never be able to get off. This is simply not true. Oxygen may be classified as a “drug”; however, it has no addictive properties.
Why patients might feel this way is when they “experiment” - going off oxygen therapy or changing how and when they use it - it immediately has a negative effect on them. The shortness of breath returns. They have difficulty doing their daily life activities and their quality-of-life declines. And all this after the oxygen therapy had made them feel good for the first time in a long while! Besides, most patients who go onto oxygen therapy, especially later in life, are going to be on it long-term. So all of this is where that feeling of addiction and of never being able to go off it comes from.
Finally, another major misconception is that once a patient goes onto oxygen therapy, they are now prisoners of their home. Nothing could be farther from the truth, especially in our technology-driven world today. Portable oxygen systems come in a variety of styles, flow capacities, weights, battery life profiles, etc. Most are FAA approved. Some are on wheels; some are designed like purses or small bags making it less obvious and easier to manage. Most are battery-operated and can be recharged via electricity or a PowerPoint in a vehicle. So a patient need not be confined indoors at all.
It amazes me that in today’s information-saturated world, some patients are still so afraid of using oxygen in their homes. All it takes for them to dramatically improve their quality of life is to check out all the information that is out there, to know that oxygen is never prescribed unless it is needed.
No fear is greater than the fear of the unknown! It is up to all those involved in the healthcare continuum to educate patients so that they get the proper information about their therapies, understand their needs, and learn to embrace rather than fear them.
