What is the partial pressure of 7% Desflurane?

To find the partial pressure of 7% desflurane, you need to apply the principle that the partial pressure of a gas in a mixture is calculated by multiplying the total pressure of the gas mixture by the percentage (expressed as a decimal) of the gas in question.

Assuming standard atmospheric pressure, which is approximately 760 mmHg, you can calculate the partial pressure of desflurane as follows:

1. Convert the percentage to a decimal: 7% = 0.07.

2. Multiply this decimal by the total atmospheric pressure:

[

0.07 \times 760 , \text{mmHg} = 53.2 , \text{mmHg}

]

The result gives approximately 53 mmHg, making it the correct choice.

This method of finding partial pressures is crucial in fields like anesthesiology, as the partial pressure of anesthetic agents like desflurane directly influences their effects and efficacy during procedures.
