Comparison of arterial blood gases in rats across different hypoxic environments.
| 21%O2 + NS group | 21%O2 + Bev group | 7%O2 + NS group | 7%O2 + Bev group | |
|---|---|---|---|---|
| PH | 7.3 (7.3, 7.4) | 7.3 (7.3, 7.4) | 7.3 (7.2, 7.3) | 7.3 (7.0, 7.3) |
| PaCO2 (mmHg) | 30.3 (24.4, 36.7) | 30.8 (26.1, 40.4) | 31.9 (30.4, 38.4) | 28.0 (25.1, 68.9) |
| PaO2 (mmHg) | 135.0 (117.0, 144.0) | 131.0 (130.0, 131.0) | 78.0 (51.0, 84.0)ab | 77.0 (69.0, 97.0)ab |
| BEecf (mmol/L) | −11.0 (−12.0, −10.0) | −7.0 (−13.0, −7.0) | −10.0 (−14.0, −6.0) | −13.0 (−16.0, −11.0) |
| HCO3 (mmol/L) | 15.6 (13.6, 17.1) | 17.9 (13.3, 19.5) | 16.1 (13.7, 19.7) | 14.9 (12.9, 15.5) |
PaO2: arterial partial pressure of oxygen; PaCO2: arterial partial pressure of carbon dioxide; BEecf: base excess of extracellular fluid.
Compared with 21%O2 + NS group, ap < 0.05; compared with 21%O2 + Bev group, bp < 0.05.
