Episode notes
Vapor Pressure and Vaporizer Safety
- Vapor pressure varies greatly among inhaled anesthetics and is proportional to temperature.
- Incorrect vaporizer filling leads to overdosing due to vapor pressure differences.
Desflurane's Unique Vaporizer
- Desflurane requires a special heated vaporizer due to its vapor pressure near atmospheric pressure.
- Heating stabilizes desflurane vaporization allowing precise anesthetic delivery.
Altitude Effects on Vaporizers
- Variable bypass vaporizers deliver consistent percentages despite altitude pressure changes.
- Desflurane vaporizers can underdose patients at higher altitudes due to atmospheric pressure effects.
