An oxygen concentrator is a medical device that draws in ambient air, filters out nitrogen, and delivers concentrated oxygen to the user through a nasal cannula or mask. Unlike traditional oxygen tanks, concentrators provide an endless supply of oxygen by continuously processing the surrounding air.

Oxygen concentrators are often prescribed for individuals with respiratory conditions such as COPD, asthma, and other disorders that cause low oxygen levels in the blood. They help maintain adequate oxygen saturation, reducing symptoms and improving overall health.

Stationary oxygen concentrators are larger, more powerful units designed for home use. They typically offer higher oxygen flow rates and longer continuous use. Portable concentrators are lighter, more compact devices that can be easily carried for use on the go, providing greater mobility and independence.

When selecting an oxygen concentrator, consider factors such as your prescribed flow rate, the device's weight and portability, battery life (for portable units), and noise level. Consult with your healthcare provider to determine the best type of concentrator (pulse dose or continuous flow) for your specific needs.
