The blood/gas partition coefficient is an indicator of…
the speed of uptake & elimination
The oil/gas partition coefficient is an indicator of….
potency
A high blood/gas partition coefficient = fast or slow anesthesia
slow
A high oil/gas partition coefficient = high or low potency
high
Does a high cardiac output speed up or slow the onset of anesthesia?
Slow, it removes more anesthetic from the lungs which slows the rise in lung and brain concentration.
Which volatile anesthetic is metabolized the most and which the least?
Sevoflurane the most (3-6%)
Desflurane the least (<0.1%)
–N2O & Iso <1%
The use of N2O with a pneumocephalogram will increase CSF pressure ____ to _____ times in _____ minutes
2-3 times in 5 min.
The use of N2O with a pneumothorax increases volume _____ - ______ times in _____ to ______minutes
2-3 times in 5 to 20
N2O with intestinal gas will _____ the volume in _____ minutes
double, 150
What happens to the size of an air bubble with the use of N2O
immediate increases in size occurs
The uptake of inhalation anesthetics is faster or slower in children compared to adults?
Faster due to higher alveolar ventilation per weight
The MAC is higher or lower in infants & children compared to adults
higher
