A 40-year-old woman is undergoing a posterior fossa craniotomy in the sitting position for clipping of a basilar artery aneurysm. Nitroprusside is being used to maintain mean arterial pressure at 50 mmHg, measured at head level. During dissection, over the course of one minute, the mean blood pressure decreases to 30 mmHg. Simultaneously, end-tidal carbon dioxide and pulmonary artery pressures decrease and heart rate increases. The most likely cause of these changes is

Two days after myocardial infarction involving the left anterior descending coronary artery, a patient's blood pressure decreases acutely from 125/80 to 70/40 mmHg, heart rate increases from 75 to 90 bpm, pulmonary artery pressure increases to 50/30 mmHg, and urine output decreases from 60 to 10 ml/hr. Thermodilution cardiac output has increased from 4 to 7 L/min. The most appropriate action is to
