Oxygen Concentrators to Use at High Elevations

If you live in or visit the mountains, you know the air becomes thinner at higher elevations. Although your body can adjust after several days or weeks, there’s still less oxygen available for you to breathe. And less oxygen to breathe also means your oxygen concentrator has less oxygen to work with. Therefore, you need an oxygen concentrator with enough strength to operate at higher elevations.

If you’re planning a trip to the mountains, but your lung capacity isn’t what it used to be, consult your doctor to ensure you’re healthy enough. If you require supplemental oxygen on your trip, an oxygen concentrator may be the best option to keep you healthy. You’ll need to ensure you’re choosing a concentrator fit to work at high elevations.

How Does Altitude Affect Oxygen?

The air becomes thinner at higher elevations, but this does not mean the air composition changes. Air consists of roughly 21% oxygen at all altitudes.

It’s the air pressure that changes at different altitudes. Lower air pressure at higher altitudes makes it feel like there’s less oxygen, making breathing more difficult, especially for people with COPD. This feeling comes from fewer oxygen molecules available for breathing as the altitude increases.

How Does Altitude Affect Oxygen Concentrators?

Gas molecules, like oxygen, carbon dioxide, and nitrogen, are crammed together closer to sea level. As air rises, it expands, and air pressure decreases, causing gas molecules to spread out, meaning you breathe less oxygen with each breath.

Not only can this become problematic for breathing, but oxygen concentrators also must work harder to take in these molecules and produce enough medical-grade oxygen for you to breathe.

Therefore, you need an oxygen concentrator strong enough to work efficiently at high elevations.

The following oxygen concentrators provide a high maximum operational elevation; you’ll receive the same high oxygen purity level without straining your machine. They’re also FAA-approved for airline travel on U.S. flights.
