Introduction to Medical Oxygen Concentrators

Medical oxygen concentrators are devices used to deliver oxygen therapy to patients who require supplemental oxygen to assist their breathing. These machines work by filtering oxygen from the surrounding air and concentrating it, before delivering it to the patient via a nasal cannula or face mask.

How Do Oxygen Concentrators Work?

An oxygen concentrator pulls air into the machine through its compressor and removes nitrogen from it with a molecular sieve. The air that is subsequently delivered to the patient is made up of more than 90% oxygen. Most oxygen concentrators are designed to produce oxygen with a concentration of 90-95%, which is considered to be medically acceptable for patients with respiratory issues.

Types of Medical Oxygen Concentrators

There are two main types of medical oxygen concentrators: stationary and portable.
