The effect of chronic hypoxia upon the development of respiratory chemoreflexes in the newborn kitten.


1. We have studied the reflex respiratory responses to two-breath alternations of fractional inspired oxygen (FI,O2) in normoxic (reared in room air) and chronically hypoxic kittens (born into and reared in an FI,O2 of 0.13-0.15) on post-natal days 1, 2-3, 4-8 and 9-14. 2. Respiration was measured non-invasively in the unanaesthetized kittens. Test runs… (More)
