LEC: Inhalent Anesthetics Flashcards
What are four factors that effect the uptake of inhalant anesthetics into the blood?
Anesthetic concentration of gas
Degree of alveolar ventilation
Cardiac output
Abnormal alveoli
What are two pro about inhalant anesthetics over injectable?
Fewer adverse effects and the anesthetic effects can be more easily controlled
Anesthetics must do what before being delivered to the CNS?
Mix into blood and achieve a threshold concentration
What is the solubility coefficient?
Blood:gas
What is the minimum alveolar concentration?
Lowest concentration of an anesthetic agent that produces no painful response to pain in 50% of anestheti zed patient
What is the minimum alveolar concentration indicative of?
Potency
What is the nitrous MAC?
188%
What is the sevoflurane MAC?
2.36%
What is isofluranes MAC?
1.2%
What is halothane Mac?
0.87%
What is methoxyflurane MAC?
0.23%
What is diffusion hypoxia?
Happens at the end with nitrous oxide and oxygen, will flood alveoli
What are six adverse effects of gas anesthesia?
Headache Nausea Fatigue Irritability Puritis Abortion
What are two ways to reduce waste anesthesia?
Scavenging systems and technique practices
