BASIC Pharmacology & Pharmacokinetics General

A 72-year-old man has massive venous hemorrhage during a radical prostatectomy. Blood pressure decreases from 110/60 to 75/30 mmHg and central venous pressure decreases from 12 to 4 mmHg. End-expiratory carbon dioxide tension decreases from 34 to 24 mmHg during constant minute ventilation. The most appropriate next step should be to

(A) apply positive end-expiratory pressure to the breathing circuit
(B) attempt to aspirate air from the central venous catheter
(C) expand intravascular volume
(D) place the patient in the Trendelenburg position
(E) turn the patient to the left lateral decubitus position

(D) PaO2 at which cerebral blood flow increases
(E) PaCO2 at which cerebral blood flow doubles

BASIC Neuro
