Effect of hypoxia on carotid chemoreceptor response to carbon dioxide in cats

摘要: Abstract Carotid nerve C 2 response curves were measured in 5 cats. activity (per cent of a maximum to asphyxia) was recorded for several values Pa co at different levels ofPa o . At higher the less given , though there considerable increases even when 450 mm Hg. lower CO curve tended flatten out as increased. However, by lowering an increase carotid could be observed. The data suggest that under conditions hypoxia two receptor systems body may stimulated or same system ways; hypoxia-produced transmitter is not essentially dependent on increased (H + ).
