Oxygen tanks are essential medical devices used to store and deliver oxygen to individuals who require supplemental oxygen therapy. They are crucial in treating respiratory conditions such as chronic obstructive pulmonary disease (COPD), asthma, pneumonia, and other conditions that impact lung function. Oxygen tanks provide a portable solution for both emergency and routine medical situations, enabling patients to maintain adequate oxygen levels in their blood. This is vital for ensuring sufficient cellular function and overall health. They are often used in hospitals, ambulatory settings, and home healthcare environments.
