Which gases will be effected the most by an increase in cardiac output? - CORRECT
ANSWER-the highest blood/gas coefficient gases (slowest)
A ventilation/perfusion deficit ________ the delivery of all anesthetic gases. -
CORRECT ANSWER-slows
Which gases will be effect most by a ventilation/perfusion deficit? - CORRECT
ANSWER-the faster inhalation agents (lowest blood/gas partition coefficient) are
effected more than the slower inhalation agents (higher blood/gas partition coefficient)
