When you're choosing a portable oxygen machine, one key decision will shape your daily comfort and mobility: continuous flow or pulse flow? At Oxygenvip, we understand how important it is to find a solution that fits your oxygen needs, whether you’re managing a chronic condition or seeking supplemental support on the go.
In this guide, we’ll break down the difference between a continuous portable oxygen concentrator and a pulse portable oxygen concentrator, and introduce some of our most trusted models to help you breathe easier—anywhere, anytime.
What Is a Portable Oxygen Concentrator?
A portable oxygen concentrator is a compact, battery-powered device that provides oxygen therapy on the move. It draws in air, filters nitrogen, and delivers concentrated oxygen to the user. Unlike traditional tanks, these machines never run out of oxygen as long as they’re powered—making them ideal for travel, home, or car use.
The two primary types are:
Understanding their differences will help you make the right choice.
What Is a Continuous Portable Oxygen Concentrator?
A continuous portable oxygen concentrator delivers a constant, uninterrupted stream of oxygen—regardless of whether you’re inhaling. It’s ideal for users with:
-
Sleep apnea
-
Severe COPD
-
High oxygen flow needs
-
Those using CPAP or BiPAP machines
Though slightly heavier and more power-intensive, a continuous portable oxygen concentrator ensures stable oxygen delivery, day or night.
