Chronic intermittent hypoxia (CIH) augments carotid body response to hypoxia in both adult and neonatal rats. Examples of carotid body responses to hypoxia in rat pups (A) and adult rats (B) exposed either to 720 episodes of CIH or to normoxia (C) are shown. Area between dashed lines indicates duration of hypoxic stimulus. Hypoxia: medium PO2 = 32 and 33 mmHg (A); medium PO2 = 33 and 34 mmHg (B). Insets: superimposed action potential from a single unit. imp/s, impulses per second.
