Answer

Answer

Hypotension after intubation is usually attributable to diminished central venous blood return to the heart secondary to elevated intrathoracic pressures. This can be treated with fluid infusions and/or adjustment of ventilatory settings to lower intrathoracic pressure (reducing PEEP, tidal volume, and, if air trapping is suspected, respiratory rate). Hypotension may also be secondary to vasovagal reaction to intubation, rapid sequence induction, sedation, and tension pneumothorax.
