40
Q

N2O special considerations

A

Requires 100% O2 5-10 min due to concentration and 2nd gas effect
Has analgesic properties
Diffuses into air containing spaces
Cannot be used alone or would be a hypoxic gas mixture

41
Q

Desflurane special considerations

A
Pungent
Rapid onset, offset
Increase SNS with rapid changes
Uses Tec 6 vaporizer
Produces CO
Ideal agent in obese patients
42
Q

Sevoflurane special considerations

A

Non-pungent - Good for inhaled induction
Fast onset/offset
Produces compound A (FGF 1 l/min X 2 hours)

43
Q

Isoflurane special considerations

A
Pungent
Slow onset/offset
Causes coronary artery vasodilation (coronary steal effect)
Produces CO
Ideal agent in CV surg
44
Q

Increase wash in

A
Increase fresh gas flows
Increase ventilation
Decrease functional reserve capacity
Decrease CO
Decrease Pa-Pv
45
Q

Decrease wash in

A
Decrease fresh gas flows
Decrease ventilation
Increase functional reserved capacity
Increase time constant
Increase dead space
46
Q

Decrease uptake

A

Decrease solubility
Decrease CO
Decrease Pa-Pv Difference

47
Q

Increase uptake

A

Increase solubility
Increase CO
Increase Pa-Pv
