15
Q

A high oil/gas partition coefficient = high or low potency

A

high

16
Q

Does a high cardiac output speed up or slow the onset of anesthesia?

A

Slow, it removes more anesthetic from the lungs which slows the rise in lung and brain concentration.

17
Q

Which volatile anesthetic is metabolized the most and which the least?

A

Sevoflurane the most (3-6%)
Desflurane the least (<0.1%)

–N2O & Iso <1%

18
Q

The use of N2O with a pneumocephalogram will increase CSF pressure ____ to _____ times in _____ minutes

A

2-3 times in 5 min.

19
Q

The use of N2O with a pneumothorax increases volume _____ - ______ times in _____ to ______minutes

A

2-3 times in 5 to 20

20
Q

N2O with intestinal gas will _____ the volume in _____ minutes

A

double, 150

21
Q

What happens to the size of an air bubble with the use of N2O

A

immediate increases in size occurs

22
Q

The uptake of inhalation anesthetics is faster or slower in children compared to adults?

A

Faster due to higher alveolar ventilation per weight

23
Q

The MAC is higher or lower in infants & children compared to adults

A

higher
