Episode notes
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.
Effects of Solubility on Induction
- The F-A/F-I ratio determines induction speed; less soluble anesthetics cause faster induction.
- Insoluble anesthetics keep alveolar gas concentration closer to inhaled levels, speeding onset.
