The concentration of carbon dioxide and the physiological response of the human body
·150～350: Impossible
·350～450ppm: Same as general outdoor environment
·350～1200ppm: Fresh air, smooth breathing
·1200～2500ppm: I feel the air is muddy and start to feel drowsy
·2500～5000ppm: Feeling headache, drowsiness, sluggishness, inability to concentrate, rapid heartbeat, mild nausea
·More than 5000ppm: may cause severe hypoxia, causing permanent brain damage, coma, and even death

Applicable environment
