During hyperventilation, we are essentially breathing in the carbon dioxide that we are expelling.
00:08
So if we have a paper bag and we are expelling co2 and then breathing co2 back in, co2 is an acid.
00:24
When combined with water, it makes carbonic acid.
00:27
So during hyperventilation, we are not expelling the carbon dioxide and blood ph will decrease.
00:41
This is because, again, co2 is an acid and any acid will decrease the ph.
00:51
So how does breathing into a paper bag help to return blood ph to normal? well, during hyperventilation, without the bag, a person is expelling.
01:05
Large amounts of, sorry, that looks maybe gross, co2.

They're not taking deep breaths...
