A patient has an actual FVC of 2.8 L and a predicted FVC of 3.7 L. What is the percent predicted?

Enhance your preparation for the Advanced Pulmonary Function Testing (PFT) Test. Utilize flashcards and multiple choice questions, complete with hints and explanations to ensure success.

To calculate the percent predicted for the FVC, you use the formula:

[

\text{Percent Predicted} = \left( \frac{\text{Actual FVC}}{\text{Predicted FVC}} \right) \times 100

]

In this case, the actual FVC is 2.8 L and the predicted FVC is 3.7 L. Plugging in these values gives:

[

\text{Percent Predicted} = \left( \frac{2.8 , \text{L}}{3.7 , \text{L}} \right) \times 100

]

Calculating the fraction:

[

\frac{2.8}{3.7} \approx 0.7568

]

Now, multiplying by 100 to convert this fraction to a percentage:

[

0.7568 \times 100 \approx 75.68%

]

This is typically rounded to the nearest whole number, which gives approximately 76%. Therefore, the percent predicted FVC of the patient is accurately represented by the choice that corresponds to 76%. Understanding this calculation is crucial in assessing a patient's pulmonary function relative to their expected
