Carbon dioxide is perhaps the most potent available modulator of cerebrovascular tone and thus cerebral blood flow (CBF). Hypercarbia and hypoxia are both potent cerebral vasodilators that result in increased cerebral blood flow and volume and, potentially, increased ICP; thus, they must be avoided. Orotracheal intubation allows for airway protection in patients who are severely obtunded and allows for better control of oxygenation and ventilation. 11. Abdominal trauma.

On arrival in the emergency department he is diaphoretic and complaining of chest pain. His blood pressure is 60/40 mm Hg and his respiratory rate is 40 breaths per minute.Which of the following best differentiates cardiac tamponade from tension pneumothorax as the cause of his hypotension? a. tachycardia b. pulse volume mottled, insensate, and motionless.
