Abstract:

The night vision scotopic sensitivity of 6 subjects was measured while they were breathing either air 21 oxygen, PO2 160 torr or 10 oxygen, balance nitrogen PO2 76 torr. Continuous monitoring showed that the mean oxygen content in the arterial blood SaO2 dropped from 97 to 77 during the first seven minutes of breathing 10 oxygen, and there was a significant degradation of scotopic sensitivity. The reduced sensitivity was attributed solely to hypoxia with no contribution from hypocapnia. Keywords Scotopic sensitivity Hypoxia Hypocapnia.
