For reference only:
250 ~ 350 ppm – Normal level outdoor air
350 ~ 1,000 ppm – Typical good living environment
1,000 ~ 2000 ppm – Level of possible oxygen shortage
2,000 ~ 5,000 ppm – Level of bad air quality, may cause
headache, sleepiness, less concentration, faster
heartbeat and mild nausea.
> 5,000 ppm – May cause severe health issues, possibly
lead to brain damage, coma and even death.
