Knowledge About Oxygen Concentrators

Your ability to get adequate sleep directly influences your cognitive health. If you require a continuous oxygen concentrator throughout the night, the last thing you want is an obstacle to a good night’s sleep. In this blog post, World Health Care is going to discuss continuous oxygen concentrators that are optimized for sleep.

World Health Care assist you in choosing, here is a list of common concerns that patients, caregivers, and clinicians have when choosing an oxygen concentrator that won’t disrupt sleep:

  1. Noise Level

  2. Continuous Oxygen Flow

  3. Power Source

  4. Energy Consumption

  5. Weight of Unit

Eliminate Sleepless Nights with the Right Oxygen Concentrator

Before we as World Health Care started the comparison discussion, there were a few guidelines we followed to narrow down the list. Each concentrator has at least two of the following features:

  • Continuous oxygen flow

  • 5 liters per minute (LPM) of oxygen output or more

Every concentrator in the list below meets these guidelines:

  1. SimplyGo Mini 5 Concentrator (Portable)

  2. Respironics SimplyGo Concentrator (Portable)

  3. Yuwell Oxygen Concentrator (Stationary)

  4. Oxymed Oxygen Concentrator (Stationary)

  5. Inogen At Home Concentrator (Portable)

  6. Respironics EverFlo Concentrator (Stationary)

  7. Devilbiss 5 LPM Concentrator (Stationary)

  8. Oxymed 10L Oxygen Concentrator (Stationary)

Noise Level

The most obvious concern is the noise level you can produce while trying to fall asleep. Fortunately, most manufacturers have built their concentrators with low ambient noise levels. The average sound emitted is between 37 and 48 decibels. Every other unit on this list is either 40 or 45 decibels. In the larger context, anything below 48 decibels will be quiet.

The video below will show you the side-by-side difference between gradual decibel changes. Start the video at (0:35) to hear the difference of a 5 decibel sound reduction and at (0:50) to hear 10 decibels of sound reduction.

The most dramatic difference is certainly the 10 decibel sound reduction. The Ever Flo Oxygen Concentrator has the lowest decibel level at 37 decibels. That’s quieter than a library or birds chirping outside your bedroom window.

The Ever Flo Oxygen 5LPM Portable Concentrator comes in at 48 decibels on continuous flow, an 11-decibel difference. The Eclipse 5 July appears to be loud, but one reviewer for this concentrator stated, “My friends and family have mostly commented on how much quieter it is…”

Continuous Oxygen Flow

World Health care noticed that for most people, continuous oxygen flow is the easiest way to manage daily oxygen needs. When you fall asleep, your breathing pattern is generally slower and shallower. But depending on how frequently you wake up (and if you have other health issues like obstructive sleep apnea), your oxygen needs may fluctuate throughout the night. And because you’re asleep, it’s hard to know how much your oxygen needs fluctuate throughout the night. Using a continuous oxygen flow setting will safely get you the oxygen you need with minimal sleep disruption.

All of the portable and stationary concentrators above can reach a maximum of 10 LPM on the continuous setting.

Power Source

Another thing to consider when purchasing an oxygen concentrator for sleep is the source of power. If your power goes out and you’re asleep, you may not even notice it. For this reason, it’s essential to have a backup plan for your oxygen unit in case this happens to you.

Some of the portable oxygen concentrators listed above have both AC and battery power sources.

Energy Consumption

Across the board, portable machines consume less power. That’s because their maximum oxygen-flow output is 2 LPM. In general, the more oxygen flow you use the more power your concentrator will consume. The average power consumption is 145 Watts. Let’s see how that compares to the stationary concentrators.

The Inogen At Home Concentrator (Stationary) is the only stationary concentrator that beats all the portable concentrators on power consumption at 120 watts, even at higher liter flows. The other stationary concentrators use anywhere from 250–350 watts of power. But again, lower liter flows will always require less power, even on the stationary concentrators.

Weight of Unit

The portable concentrators are the obvious choice here because they’re made to be transported easily. Every portable concentrator is less than 20 pounds, with the Philips SimplyGo coming in with the lightest weight at 10 pounds.

The Inogen At Home Concentrator (Stationary) is also very competitive with portable units for weight, coming in at only 18 pounds. Most stationary concentrator weighs anywhere from 31–36 pounds. If you want the lightest unit, your best option includes any portable concentrators or the Inogen At Home Concentrator.

Final Thoughts from World Health Care

There are undoubtedly many things to consider when choosing an oxygen concentrator for your best night’s sleep and having a quiet and energy-efficient concentrator (that can safely meet your oxygen needs) will help you sleep better at night.
