inhalant agents Flashcards
MAC
Potency
how is concentration of anesthesia in the body changed
adjusting the delivered concentration to the patient
how are inhalants eliminated
by lungs with minimal metabolism
what is the max exposure of inhalants to people
2ppm
what is more expensive, inhalant or injectable
inhalants
what color are oxygen tanks
green
what does an E tank contain
2200psi, 660 L
what does an H tank contain
2200psi, 6600 L
what used to be the most widely used anesthetic but is now outdated
diethyl ether
advantage of mask induction
easy if dosile and calm
what is low partition coefficient
rapid induction and recovery along with rapid response to changes in concentration during maintenance
what will maintain moderate surgical anesthesia
1.5xMAC
what does low MAC
high potency
values of ideal agent
low VP, low SC, low MAC
