Role of the carotid chemoreceptors in the respiratory response of newborn lambs to alternate pairs of breaths of air and a hypoxic gas.

Abstract

We measured the reflex respiratory response to a 2-breath alternation in fractional inspired oxygen in two groups of lambs. Test runs where F(I),O2 was made to alternate (between 0.21 and 0.14) were compared with control runs in which it was held at 0.21. Within 36 h of birth we cut the carotid sinus nerves bilaterally in one group of lambs (n = 5) whilst… (More)
