HOW TO DETECT CO2 LEVELS
High CO2 concentration levels affect our performances at school as in office
Every day we hear news about damages caused by pollution on our health. Unfortunately, we still don’t know much about other polluting substances which are very harmful on both our brain and our body.
The New York Times wrote about meetings held in small and crowded rooms: are these meetings so strategic and efficient?
A study published by the Journal of Cerebral Blood Flow and Metabolism noted that high levels of carbon dioxide can cause blood vessels dilate in brain, reduce both brain activity and information flow between brain regions.
For this reason, it is very important to aerate rooms at least 2/3 times a day to allow air turnover and decrease CO2 concentration, which is regarded as an important measure of indoor air quality.
Air quality: how can it be defined?
The air quality measures the indoor air conditions and it is calculated in % or ppm (par per million). Every day, everyone spend 80% of the time indoor, breathing 22.000 times about and producing high levels of CO2.
In addition of CO2, we also find in the air:
– Physical and chemical agents
– Biological agents
These agents affect the breath system causing allergies, asthma and immune system problems.
The optimum value of air quality should be under 10.000 ppm (of CO2).
Nowadays more and more buildings (smart buildings) are projected to save energy using windows to separate rooms: unfortunately, in these places, the air turnover is not so easy. For this reason, offices, schools and private houses should have efficient air exchangers.
Bleb Technology has developed a specific CO2 sensor: in case of detected critical situation, it informs people to promptly act: eg. open windows, allow automatic activation of specific devices such as air turnover systems, electric blinds etc.
