What is the vapor pressure of isoflurane?

Isoflurane is an inhalational anesthetic commonly used in clinical practice. Its vapor pressure is a critical property because it influences the delivery of the anesthetic during surgery.

The vapor pressure of isoflurane at room temperature is approximately 240 mmHg. This characteristic allows for efficient inhalation and control of anesthetic depth during surgical procedures. A vapor pressure of 240 mmHg indicates that isoflurane has a relatively high tendency to evaporate, which means it can be easily maintained in a vaporized state in an anesthetic machine for patient administration.

Understanding the vapor pressure helps anesthesiologists and medical professionals to gauge how the anesthetic behaves in different conditions and how it will distribute in the body. The correct identification of this value is essential for safe and effective anesthesia practice.
