All About Oxygen

Expand All

What is oxygen therapy?


Oxygen therapy increases the amount of oxygen your lungs receive and deliver to your blood. Oxygen therapy may be prescribed for you when you have a condition that causes your blood oxygen levels to be too low. Click to learn more about Lincare’s Oxygen Therapy services.

How do I use home oxygen*?


You can use either an oxygen mask or nasal cannulas to deliver supplemental oxygen to your lungs. An oxygen mask fits over your nose and mouth, while a small, adjustable plastic tube, called a nasal cannula, attaches to your concentrator or tank and facilitates oxygen flow to your lungs. We have provided The Patient's Guide to Oxygen Therapy with more comprehensive information on oxygen treatment. (*Use oxygen as prescribed by your practitioner)

How can I tell if I need supplemental oxygen?


If breathing becomes more difficult, or you are experiencing fatigue, dizziness, or shortness of breath, you may need supplemental oxygen. Your prescribing practitioner can measure the amount of oxygen in your blood with an Arterial Blood Gas (ABG) test or an oximeter to determine if you need supplemental oxygen therapy. Click to learn more about Signs You May Not Be Getting Enough Oxygen.

How can I tell if I am getting the right amount of oxygen?


You may experience a decrease in symptoms when using oxygen, but the only way to accurately determine if you are getting the right amount of oxygen is to have the oxygen level in your blood measured while using supplemental oxygen. If new symptoms, such as headaches, confusion, or increased fatigue appear, you may be getting too much oxygen. If your symptoms do not improve, you may not be getting enough oxygen. If you experience any of these symptoms, reach out to your prescribing practitioner to discuss whether a change in your prescribed treatment is needed.

How long will I need to continue my oxygen therapy?


Some patients may use oxygen at home for years, while others use it temporarily to relieve discomfort, stress, or other underlying reasons. This will differ depending on your medical condition and individual needs, and your practitioner's prescription.

Do I have to use oxygen all the time?


Your prescribing practitioner will determine how many hours per day you should use oxygen, and you should follow the prescribed routine.

How do I get around my home while using oxygen?


A variety of equipment options can help meet your individual needs and activities. Equipment is typically placed where it will be used most often, and extension tubing allows you to move more freely.

How heavy are portable tanks?


The weight of portable tanks vary depending on the size. Smaller tanks weigh approximately 5 pounds and are designed to be carried in a shoulder bag while larger tanks containing more oxygen for longer periods of use are approximately 15 pounds and are pulled on a cart.

Is there anything I can't do while using oxygen?


You can participate in your usual activities, except for those involving open flames, smoking, or anything that can cause a spark. The use of oxygen may enable you to perform some activities you might otherwise have to avoid.

Can I refill a portable tank myself?


No. High-pressure tanks should only be refilled by Lincare or an authorized provider.

Can I drive a car or travel while using oxygen?


Yes, as long as there's no other medical condition prohibiting you from driving a car or traveling. When driving, secure the portable oxygen device so it does not tip or fall. You can also travel on public transportation while using oxygen. Learn more about Flying with your Portable Oxygen Concentrator.

What do I do if I run out of oxygen?


Call your center to replace or refill the cylinder.

Can I become addicted to oxygen?


No. Oxygen is not addictive.

Will oxygen relieve my shortness of breath?


Supplemental oxygen can relieve shortness of breath. However, there may be some conditions that are not relieved by oxygen.

How do I choose a home oxygen supplier once my physician prescribes it?


When selecting an oxygen supplier, you always have a choice. Find out if your potential supplier will deliver and install your equipment. See how flexible they are with delivery. Find out if they will bill Medicare or your insurance directly, if they provide in-home visits with a nurse or therapist, and whether they offer 24/7 service.

How much does home oxygen cost, and does Medicare or my insurance cover it?


Home oxygen costs vary depending on prescription needs and the type of equipment. Your supplier can select the most economical system to meet your prescription requirements and estimate the monthly costs.

Can I cook and eat while using oxygen?


Never cook over an open flame, and make sure your oxygen tubing does not come in contact with anything that could damage or melt the tube's plastic. Using oxygen while eating may reduce the shortness of breath that many patients experience during and after eating.

Can I use electrical appliances while using oxygen?


Yes, as long as the electrical appliance does not spark during operation.

How can I maintain my oxygen therapy outside of my home?


Portable tanks allow you to take your oxygen on the go. Some even hold enough oxygen for up to eight hours of continuous use. There are optional refillable tanks that you may be able to utilize for travel; contact your local Lincare Center to see if this is appropriate for you.

Are there any hazards involved in using oxygen?


Avoid open flames, burning cigarettes, and electrical equipment that can spark during use. Never use oil, grease, or petroleum jelly on your face while using oxygen equipment. If frost forms on the equipment, avoid contact with your skin. Be sure to follow your prescribing practitioner's orders when using oxygen and never change the liter flow without their approval.
