What is the general anesthesia triad? - CORRECT ANSWER - reversible LOC
reversible analgesia
muscle relaxation
What is TIVA? - CORRECT ANSWER - Total Intravenous Anesthsia
What are the criteria for conscious sedation? (4) - CORRECT ANSWER - responsive to
verbal stimuli
unaffected airway
spontaneous ventilation
normal vital signs and cardiac fxn
What is MAC sedation? - CORRECT ANSWER - Monitored Anesthesia Care Sedation
What are the criteria for MAC sedation? (4) - CORRECT ANSWER - purposeful movement
to repeated pain
spontaneous ventilation - may require assistance
airway may be lost - may require intervention
usually normal cardiac fxn -may require assistance
What are the criteria for General Anesthesia? (4) - CORRECT ANSWER - no response to
stimuli
no spontaneous ventilation (or requires support)
airway often requires intervention/support
, cardiac often requires intervention
Describe the ideal anesthetic (10) - CORRECT ANSWER - pleasant, non-irritating odor
low blood/gas solubility
chemically stable in storage, not interactive with machine
