Table 2.
Systolic blood pressure, heart rate, arterial partial pressure of oxygen (PO2), arterial partial pressure of carbon dioxide (PCO2), and arterial pH were monitored at 3- to 6-h intervals during prolonged MV
| Physiological Variable | MV-LCR | MV-HCR |
|---|---|---|
| Systolic blood pressure, mmHg | 102 ± 4 | 103 ± 4 |
| Heart rate, beats/min | 380 ± 8 | 352 ± 7* |
| Arterial pO2, mmHg | 73 ± 3 | 73 ± 2 |
| Arterial pCO2, mmHg | 30 ± 1 | 33 ± 1 |
| Arterial pH | 7.46 ± 0.01 | 7.45 ± 0.01 |
Values are expressed as means ± SE.
