MAP < 50 mmHg
the more soluble an anesthetic agent is in the blood
the slower the patient is anesthetized
which inhalational agent is the most soluble
isoflurane
which agent is characterized by a slower induction and wakeup
isoflurane
which inhalational agent has poor solubility
desflurane
a higher MAC will have a [higher/lower] B:G coefficient
lower
which gases are non-pungent
sevoflurane, halothane, and nitrous
