I just came across your website as I was researching on hypoxia. My name is Victor from Kenya, Africa.
My younger brother (32 yrs old) collapsed(cardiac arrest) on 10th Jan 2020 in Dubai and was rushed to hospital. He has been in ICU since then. We learned that he was out of oxygen for about 20 minutes before the ambulance picked him and the doctors spent about 40 minutes trying to get a pulse from him.
Therefore he got hypoxia(not sure of the severity).
The last 3 days he has shown great improvement and has been off the ventilator for 24 hours now. His consciousness level is still below per but better than before(from 5% to 10%).
I just felt I needed to share with people who understands. I know this is lifechanging and I want to learn as much as I can in terms of after care.
