What is the vapor pressure of Desflurane?

Desflurane is an inhalational anesthetic that is known for its low blood solubility and high volatility. This property is reflected in its vapor pressure, which is a critical parameter when considering its use in anesthesia. The vapor pressure of a substance is the pressure exerted by its vapor when it is in equilibrium with its liquid phase at a given temperature.

For Desflurane, the vapor pressure is approximately 669 mmHg at 20 degrees Celsius. This high vapor pressure indicates that Desflurane readily evaporates, allowing for effective delivery as an anesthetic agent during surgical procedures. Its characteristics make it particularly useful for rapid inductions and recoveries in anesthesia due to how easily it can be vaporized and inhaled.

The other given values do not accurately represent the vapor pressure of Desflurane, which is established through chemical data and clinical usage, underscoring the importance of understanding the characteristics of anesthetics in practice.
