Talk:Silent hypoxia

How does this compare symptomatically with hypoxic or asphyxiant gases
How does this compare symptomatically with a healthy person breathing carbon dioxide free hypoxic breathing gas mixtures like heliox with 10% oxygen, or scrubbed rebreather mix without oxygen makeup, or asphyxiant gases like helium, argon, or nitrogen? &middot; &middot; &middot; Peter Southwood (talk): 06:13, 28 November 2022 (UTC)

Carbon dioxide tolerance?
In persons with high work of breathing a raised tolerance to blood CO2 could have the effect reported for COVID and pneumonia. I think the mechanism for hypoxic breathing gas is reasonably well known. &middot; &middot; &middot; Peter Southwood (talk): 06:12, 29 November 2022 (UTC)
