Introduction: Why Canned Oxygen Is a Breath of Fresh Air
Let’s face it: we all have moments when we could use a little more air. Whether you’re hiking above the clouds, battling brain fog, or dragging after leg day, your body and brain thrive on one thing – oxygen. And while the air around you is about 21% oxygen, a can of portable, purified oxygen? That clocks in at a potent 98% pure oxygen.
REV/O2 Oxygen is also all-natural, emphasizing its safety and suitability for use.
This guide unpacks the science and the benefits of canned oxygen, separating hype from facts, and giving you everything you need to know to breathe smarter – wherever you are.
What Is Canned Oxygen?
Canned oxygen, sometimes called recreational or supplemental oxygen, is a lightweight, portable canister filled with nearly pure oxygen. It’s available over the counter (no prescription required) and designed to give your system a short-term oxygen boost.
Most products come with a mouthpiece and a trigger-activated valve that releases oxygen when pressed. Unlike medical-grade oxygen tanks used for chronic illnesses, canned oxygen is intended for non medical use by healthy individuals looking to support focus, recovery, or altitude adjustment. The delivery system is crucial in ensuring effective oxygen administration, as different methods can significantly impact the actual oxygen levels received.
Understanding Oxygen Therapy
Oxygen therapy is a medical treatment designed to provide supplemental oxygen to individuals with lung diseases or breathing problems, ensuring their bodies receive enough oxygen to function properly. When the air we breathe doesn’t supply sufficient oxygen, supplemental oxygen, such as REV/O2 oxygen, steps in to fill the gap. This therapy is often prescribed for conditions like chronic obstructive pulmonary disease (COPD), pneumonia, or bronchitis, where the body’s oxygen needs exceed what ambient air can provide.
For those living in or visiting high-altitude areas, where oxygen levels in the air are lower, oxygen therapy becomes crucial. High altitudes can lead to altitude sickness, characterized by symptoms like headaches, dizziness, and shortness of breath. Supplemental oxygen helps alleviate these symptoms by boosting the oxygen content in the blood, ensuring the body gets the oxygen it needs to function optimally. Whether you’re a mountain climber or someone with a respiratory condition, understanding and utilizing oxygen therapy can make a significant difference in your well-being.
The Science of Oxygen

Oxygen is the lifeblood of our bodies, essential for maintaining healthy organs and tissues. When we breathe in air, our lungs filter out the oxygen, which is then transported to the body’s tissues via the bloodstream. This process is vital for energy production and overall cellular function. Typically, the air we breathe contains about 20% oxygen, but our bodies sometimes need more, especially under stress or in low-oxygen environments.
Oxygen saturation, a measure of the amount of oxygen in the blood, is a critical indicator of health. A healthy oxygen level is typically 95% or higher. When oxygen levels drop below this threshold, a condition known as hypoxemia, it can lead to serious health issues, including organ damage and failure. This is where oxygen therapy and supplemental oxygen come into play. By providing medical-grade oxygen, these treatments ensure that the body receives enough oxygen to function properly, preventing complications and supporting overall health. For individuals with lung diseases or breathing problems, maintaining proper oxygen saturation is crucial, and oxygen therapy can be a lifesaver.
Who Uses Canned Oxygen and Why?
The short answer? A lot of people. Here are the most common use cases:
- Athletes & fitness enthusiasts: to enhance stamina and reduce recovery time. Canned oxygen can help maintain energy levels during intense physical activities.
- High-altitude travelers: to combat low oxygen levels and altitude sickness. Canned oxygen can assist with altitude acclimation, making it easier to adjust to high altitude environments.
- Busy professionals & students: for mental clarity and productivity
- Older adults: to support everyday movement and breathing
- Wellness lovers: to support stress relief and relaxation
In fact, as our lifestyles become more demanding—mentally, physically, and environmentally—the demand for functional wellness tools like canned oxygen continues to rise. You might be surprised to find a can tucked in someone’s gym bag, travel kit, or even office drawer.
How Canned Oxygen Works
When you breathe in supplemental oxygen, you’re delivering a burst of concentrated O2 to your lungs. From there, oxygen is absorbed into your bloodstream and delivered to tissues, organs, and muscles. Taking a deep breath of the pure oxygen provided by the canister can elicit a refreshing and energizing effect, making it particularly beneficial for recovery after workouts or to alleviate feelings of fatigue. This can support energy metabolism, aid mental function, and reduce feelings of fatigue.
The effect is temporary but fast-acting, often noticeable within seconds of inhalation. Because oxygen is a key driver of cellular energy production, even a slight uptick can create a perceived improvement in alertness, stamina, and recovery. The extra oxygen provided by the canisters can enhance physical and mental performance, making it useful for athletic activities, high-altitude travel, and overall wellness during and after physical exertion.
Canned Oxygen vs. Room Air
Let’s do the math:
- Ambient air: ~21% oxygen
- Canned oxygen: 95–98% oxygen

At high altitudes, lower barometric pressure reduces the oxygen levels in the air, which poses risks such as altitude sickness and challenges the body's ability to maintain optimal oxygen levels in the bloodstream.
That jump in concentration can be a game changer during physical exertion, mental strain, or oxygen-depleted environments (like 8,000 ft elevations or stuffy gym basements). In such high-altitude environments, lower oxygen levels necessitate the use of supplemental oxygen to help the body adjust and mitigate the risk of altitude sickness.
It’s not about replacing what your lungs already do. It’s about offering a targeted boost when your system needs it most—especially when your environment or activity level demands more than what ambient air can deliver. Use our Altitude Oxygen Calculator to check our O2 levels.

Air Quality and Oxygen

Poor air quality can significantly impact our health, leading to low oxygen levels (hypoxemia) and exacerbating lung diseases or breathing problems. Air pollution, a common culprit, reduces the oxygen content in the air, making it harder for our bodies to get the oxygen they need. In such scenarios, supplemental oxygen becomes a necessary treatment to ensure adequate oxygen levels in the blood.
Oxygen bars and oxygen tanks offer supplemental oxygen to help increase oxygen levels, but they may not be suitable for everyone, especially those with medical conditions. Recreational oxygen, while beneficial for short-term use, is not a substitute for medical-grade oxygen and should be used under the guidance of a healthcare provider. Canned oxygen, such as REV/O2 oxygen, provides a convenient way to increase oxygen levels, particularly in environments with poor air quality. However, it’s essential to remember that while canned oxygen can offer temporary relief, it is not a replacement for medical-grade oxygen for those with serious health conditions.
