Interventions
DRUG

Phenylephrine

blood pressure will be increased or decreased by using one of six interventions: phenylephrine (alpha-1 agonist), dexmedetomidine (alpha-2 agonist), clevidipine (Ca channel blocker, CaCl, tetanic stimulus and increase in venous pressure

DRUG

Dexmedetomidine

blood pressure will be increased or decreased by using one of six interventions: phenylephrine (alpha-1 agonist), dexmedetomidine (alpha-2 agonist), clevidipine (Ca

DRUG

Clevidipine

blood pressure will be increased or decreased by using one of six interventions: phenylephrine (alpha-1 agonist), dexmedetomidine (alpha-2 agonist), clevidipine (Ca

OTHER

tetanic stimulus

A 5 second 70 mA tetanic stimulus will be applied to elicit peripheral vasoconstriction (stress response)

OTHER

Increased venous pressure

A 5 minute inflation of a noninvasive blood pressure cuff to 30 mmHg to increase venous pressure in the arm with the pulse oximeter probes.

DRUG

Calcium Chloride

CaCl will be administered to increase blood pressure and plasma calcium concentration
