|
What are the benefits of inhalant anesthesia?
|
relatively cheap
predictable Fast onset/offset Supplemental O2 |
|
|
What are the two disadvantages of inhalant anesthesia?
What is the maximum exposure of inhalant anesthesia? |
requires an apparatus
health and environmental hazard 2ppm (25ppm N2O) |
|
|
How do you calculate the maximum concentration of gas?
|
vapor pressure of gas/atmospheric pressure X 100
|
|
|
What are the ideal characteristics of inhalant anesthesia?
|
non-toxic
non-flamable low blood solubility stable inexpensive minimal excitement minimally metabolized |
|
|
What is the benefit of inhalant with a low solubility/partition coefficient?
|
fast onset and recovery
high solubility will have slow onset and recovery |
|
|
What factors determine the rate of uptake of inhalant from alveoli to the blood?
|
-blood gas solubility
-cardiac output -difference in concentration of inhalant in pulmonary arteries and pulmonary veins |
|
|
What order is cardiac output received in the body?
|
vessel rich
muscle Fat vessel poor this is important to tell you how fast the anesthetic will reach different parts of the body |
|
|
What are the factors that affect the rate of elimination?
|
-alveolar ventilation
-cardiac output -solubility of drug -duration of drug -Breathing circuits (non re-breathing recover faster due to high flow rates) |
