What level of co2 is toxic to humans?
From 2000 to 5000 ppm, CO2 concentration starts to cause problems (headaches, insomnia, nausea).
It is a dirty air.
From 5000 ppm, the presence of other gases in air is altered, arising a toxic atmosphere or poor in oxigen with fatal effects as the concentration increases..

What does a carbon dioxide level of 33 mean?
Normal values in adults are 22 to 29 mmol/L or 22 to 29 mEq/L. Higher levels of carbon dioxide may mean you have: Metabolic alkalosis, or too much bicarbonate in your blood. Cushing disease. Hyperaldosteronism, an adrenal gland problem.
Is 10 ppm of carbon monoxide dangerous?
0-9 ppm CO: no health risk; normal CO levels in air. 10-29 ppm CO: problems over long-term exposure; chronic problems such as headaches, nausea. … 100+ ppm CO: severe symptoms; confusion, intense headaches; ultimately brain damage, coma, and/or death, especially at levels 300-400+ ppm.
What happens when your carbon dioxide levels are too high?
Hypercapnia is excess carbon dioxide (CO2) build-up in your body. The condition, also described as hypercapnea, hypercarbia, or carbon dioxide retention, can cause effects such as headaches, dizziness, and fatigue, as well as serious complications such as seizures or loss of consciousness.
What is a safe co2 level indoors?
What levels of CO2 are considered safe? Carbon dioxide is not generally found at hazardous levels in indoor environments. The MNDOLI has set workplace safety standards of 10,000 ppm for an 8-hour period and 30,000 ppm for a 15 minute period.
