Anesthetic State

It is a global but reversible _____ of the central nervous system function resulting in the loss of response to and perception of all _____

A

Anesthetic State

It is a global but reversible depression of the central nervous system function resulting in the loss of response to and perception of all stimuli.

17
Q

Induction of anesthesia

the time from ______of general anesthetic to the _____ of surgical anesthesia

A

Induction of anesthesia

the time from administration of general anesthetic to the achievement of surgical anesthesia

18
Q

Induction depends on how fast the anesthetic reaches the _____(inhaled or intravenous)

A

CNS

19
Q

In order to reach the CNS the anesthetic must be transferred from the alveolar ___ to blood and from blood to ____.

A

In order to reach the CNS the anesthetic must be transferred from the alveolar air to blood and from blood to brain.

20
Q

•Recovery depends on how quickly the anesthetic is removed from the ____.

A

blood

Q

three most important factors that influence rate of induction for inhaled anesthetics:

three most important factors that influence rate of induction for inhaled anesthetics:

  1. The solubility in blood (blood gas/partition coefficient)
