The doctor also does another neuro assessment. "Oh no! He has a blown pupil," he says. You know that a fixed, dilated pupil indicates even higher pressure inside the skull. Why would water shots cause pressure to increase inside the patient's skull?

11.1 If the pressure in the CSF is measured as shown in the Figure, using a spinal tap with the patient sitting erect, then the pressure due to the weight of the CSF in the spinal column increases the pressure. (a) What pressure is measured in centimeters of water if the pressure around the brain is 10 mm Hg, and the tap is at a point 60 cm lower than the brain? (b) What pressure in centimeters of water is measured if the patient lies down? The density of CSF is 1.05 g/cm³.
