Sitting up (ortho) and leaning over a table to breathe (pneic)

Pollutant
A harmful chemical or substance in the air or water
Pulse Oximetry
Measures (metry) the oxygen (oxi) concentration in arterial blood

When breathing stops
Respiratory Depression
Slow, weak respiration at a rate of fewer than 12 per minute
