What are the typical tank sizes for home oxygen therapy?

The E tank and M tank are the typical sizes used for home oxygen therapy because they strike a balance between portability and sufficient oxygen supply for patients. The E tank is commonly used in home settings due to its manageable size and weight, making it easier for patients to transport as needed. It can provide sufficient oxygen for several hours, depending on the prescribed flow rate, making it practical for daily activities.

The M tank, while less common than the E tank, offers a larger volume and is suitable for longer durations when patients might require extended oxygen therapy without frequent changes of tanks. This is particularly beneficial for individuals who need to use oxygen throughout the day and night.

In contrast, other options like the A, D, C, F, G, and H tanks are either too small for effective home therapy, or too large and cumbersome, which would not be ideal for most home oxygen therapy requirements. The focus on E and M tanks reflects the need for a balance of accessibility and oxygen supply that meets the everyday needs of patients in a home environment.
