Data are means ± SD for age, height, weight, BSA, and BMI. Means ± SE are reported for all other data. N = number of subjects. BMI, body mass index; BSA, body surface area; etCO2, end tidal carbon dioxide; HR, heart rate; MAP, mean arterial pressure; MCAv, middle cerebral artery velocity; PCAv, posterior cerebral artery velocity; ScO2, cerebral oxygen saturation; SVi, stroke volume indexed to BSA. Unpaired t tests were used to compare male and female subjects.
