An oxygen concentrator is a medical device designed to deliver supplemental oxygen to individuals who experience low blood oxygen levels. Unlike oxygen cylinders, which store compressed oxygen, concentrators extract oxygen directly from the surrounding air, making them more convenient and cost-effective for long-term use. This article explores how oxygen concentrators work, their benefits, the types available, and the best places to buy or rent them.

How Does an Oxygen Concentrator Work?

Oxygen concentrators use a technology called Pressure Swing Adsorption (PSA). Room air is drawn in, nitrogen is filtered out, and concentrated oxygen (usually around 90–95%) is delivered to the patient through a nasal cannula or mask. This ensures a continuous supply of oxygen without the need for frequent cylinder refills.

Benefits of Using an Oxygen Concentrator

• Cost-Effective: Reduces dependency on oxygen cylinders, lowering long-term costs.


• Continuous Oxygen Supply: Provides oxygen as long as the concentrator has power.


• Mobility Options: Portable models allow patients to maintain an active lifestyle.


• Safety: Eliminates the risks associated with storing large oxygen tanks.


• Ease of Use: Simple interface and minimal maintenance requirements.

Types of Oxygen Concentrators

Oxygen concentrators come in different sizes and designs to meet patient needs:

• Stationary Oxygen Concentrators: Designed for home use, offering higher oxygen output but requiring an electrical source.


• Portable Oxygen Concentrators (POCs): Compact and battery-powered devices that provide oxygen on the go, ideal for travel and outdoor use.


• Pulse Dose Models: Deliver oxygen only when the user inhales, conserving energy and extending battery life.


• Continuous Flow Models: Provide a constant flow of oxygen, often prescribed for patients with higher oxygen needs.
