How much oxygen is there in the air? Everything you need to know

Jul 09 2024 Kristoffer Jensen

When we think about indoor climate and air quality, we often overlook the essential aspect of the oxygen content of the air we breathe every day. Oxygen is not just essential for life – it is crucial for our well-being.

The percentage of oxygen in the atmosphere

The composition of the atmosphere consists of approximately 21% oxygen , 78% nitrogen, 0.038% carbon dioxide and 0.93% argon. This balance is vital, as oxygen plays a central role in cellular respiration and energy production. If you want to know more about how you can improve your indoor climate , you will find good advice and tips on our blog.

Why is oxygen important?

Oxygen enables the body's cells to convert glucose into energy. Lack of oxygen can result in symptoms such as fatigue, dizziness and, in extreme cases, unconsciousness. Effective ventilation is therefore essential to maintaining healthy oxygen levels indoors – and this is where our IoT solutions come into play.

The risks of too much or too little oxygen

While adequate oxygen levels are necessary, too high a level can also be problematic. Overoxygenation can lead to oxygen toxicity, which can potentially damage both the lungs and central nervous system. For a deeper look into these risks, you can read about the subject at Crowcon , for example.

Indoor climate and oxygen

In modern buildings, the oxygen content can vary greatly depending on factors such as ventilation, the number of people in the room and the amount of pollutants. It is essential to ensure a continuous supply of fresh air. According to our blog on CO2, plants or ventilation, ventilation is one of the most effective methods to achieve this, although plants can also contribute to improved air quality.

Measure and optimize your oxygen content

To ensure that you always have a healthy oxygen level, it may be a good idea to measure air quality continuously. Our smart IoT solutions from ÅBN make it possible to monitor the indoor climate in real time – and thus act quickly if challenges arise.
