Group data for adult, acute hypoxic phrenic responses to moderate (PaO235–45 mmHg) and severe (PaO225–35 mmHg) hypoxia demonstrate no differences after neonatal (P4) saline or LPS (1 mg/kg, i.p), or after adult ketoprofen (12.5 mg/kg, i.p, 3 hr) within each sex. Significant differences between sexes demonstrate larger responses in females after moderate or severe hypoxia († p<0.05, ††† p<0.001). *p<0.05 from male neonatal LPS. Moderate hypoxia: neonatal saline male (n = 7), neonatal LPS male (n = 10), neonatal saline female (n = 6), neonatal LPS female (n = 6). Keto + Moderate hypoxia: neonatal saline male (n = 4), neonatal LPS male (n = 4), neonatal saline female (n = 5), neonatal LPS female (n = 5). Severe hypoxia: neonatal saline male (n = 5), neonatal LPS male (n = 4), neonatal saline female (n = 4), neonatal LPS female (n = 4). Keto + Moderate hypoxia: neonatal saline male (n = 5), neonatal LPS male (n = 5), neonatal saline female (n = 5), neonatal LPS female (n = 6).
