If you have been prescribed oxygen therapy, your doctor might have given you the choice between either a portable oxygen concentrator or a home unit. Both of these machines are designed to increase the amount of oxygen in your blood, but they work differently and are suited for different situations. Here is what you need to know about both varieties so that you can make an informed decision about which one is best for you.

Home Oxygen Concentrators

portable oxygen concentrator

Home oxygen concentrators are larger machines that are designed to be used in one specific location, such as your home or office. They work by taking in the surrounding air and using a filter to remove impurities and increase the concentration of oxygen. These units are usually more powerful than portable ones and can provide you with higher concentrations. However, they are not meant to be mobile and can be difficult to take with you if you travel or leave your house often.

When it comes to output, home models deliver up to 5 liters per minute. Liters per minute is a measurement of how much oxygen the machine can produce and is an important consideration when choosing a concentrator.

A higher output means that the machine can provide more oxygen to your body, which can be beneficial if you have a lot of tissue damage or are very active. However, it is important to note that a higher output also means that the machine will use more power and will need to be plugged into an outlet.

Portable Oxygen Concentrator

Portable units are smaller machines that can be easily transported. They work similarly to home concentrators, but use battery power instead of being plugged into an outlet. This makes them convenient for people who are on the go, as well as for travel, vacations, and more.

Portable oxygen concentrators generally provide a lower concentration than home machines. However, they are still effective at increasing the amount of oxygen in your blood. They can manage up to 2 liters per minute. Though this will be helpful for most people, consult with your physician to ensure these levels will be adequate for your needs.

If you are relatively sedentary and don't leave your house often, a home oxygen concentrator might be the best choice for you. However, if you travel frequently or are on the go, portability may be an important feature for you.
