Final answer:
The vapor pressure of an anesthetic substance determines its ability to be administered as a gas or a vapor for inhalation.
Step-by-step explanation:
The relationship between vapor pressure and anesthetic delivered is that the vapor pressure of an anesthetic substance determines its ability to be administered as a gas or a vapor for inhalation.
When an anesthetic is delivered, it is either in the form of a volatile liquid or a gas. Inhalational anesthetics are usually delivered using an anesthesia machine, which allows for the composition of a mixture of oxygen, anesthetics, and ambient air to be delivered to the patient.
If an anesthetic is a liquid, it needs to be vaporized in the anesthesia machine before it can be administered. The vapor pressure of the anesthetic substance determines how easily it can be vaporized and delivered to the patient.
