Physiological variables immediately before CBF measurement
| Physiological Variable | Saline Controls | Scopolamine | |
|---|---|---|---|
| 0.4 mg/kg | 0.8 mg/kg | ||
| n | 7 | 6 | 5 |
| Mean arterial blood pressure (mm Hg) | 107 ± 2 | 110 ± 2 | 110 ± 2 |
| pACO2 (mm Hg) | 36 ± 1 | 35 ± 1 | 36 ± 1 |
| pAO2 (mm Hg) | 90 ± 3 | 90 ± 2 | 91 ± 3 |
| Arterial pH | 7.44 ± 0.01 | 7.44 ± 0.01 | 7.43 ± 0.01 |
| Arterial HCO3 −concentration (mM) | 26.0 ± 0.4 | 25.0 ± 0.4 | 25.0 ± 0.4 |
Values are means ± S.E. of n animals. No statistically significant differences between scopolamine-treated and control animals for any of the variables.
