N2O special considerations
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
Desflurane special considerations
```
Pungent
Rapid onset, offset
Increase SNS with rapid changes
Uses Tec 6 vaporizer
Produces CO
Ideal agent in obese patients
```
42
Sevoflurane special considerations
Non-pungent - Good for inhaled induction
Fast onset/offset
Produces compound A (FGF 1 l/min X 2 hours)
43
Isoflurane special considerations
```
Pungent
Slow onset/offset
Causes coronary artery vasodilation (coronary steal effect)
Produces CO
Ideal agent in CV surg
```
44
Increase wash in
```
Increase fresh gas flows
Increase ventilation
Decrease functional reserve capacity
Decrease CO
Decrease Pa-Pv
```
45
Decrease wash in
```
Decrease fresh gas flows
Decrease ventilation
Increase functional reserved capacity
Increase time constant
Increase dead space
```
46
Decrease uptake
Decrease solubility
Decrease CO
Decrease Pa-Pv Difference
47
Increase uptake
Increase solubility
Increase CO
Increase Pa-Pv
