What is the vapor pressure of desflurane?

Desflurane is a volatile anesthetic that is known for its low solubility in blood and high vapor pressure, which allows for rapid induction and emergence from anesthesia. The vapor pressure of desflurane at room temperature (approximately 20°C to 25°C) is about 669 mmHg. This high vapor pressure is significant as it reflects the anesthetic's volatility and ability to quickly transition from liquid to gas at relatively low temperatures, making it particularly useful in clinical settings where quick changes in anesthetic depth are required.

This characteristic of desflurane allows anesthesiologists to adjust dosages swiftly and effectively, aiding in both induction and recovery. Understanding the vapor pressure of anesthetics like desflurane is critical for safe and effective anesthesia management, ensuring that patients receive the appropriate level of sedation during procedures.
