During pulmonary function testing, what parameters are entered into the PFT computer to calculate predicted values?
Understand the Problem
The question is asking which parameters are used in pulmonary function testing (PFT) to calculate predicted values. It provides four options and is looking for the correct one that includes the necessary demographic and physiological factors.
Answer
Age, height, sex, and sometimes ethnicity.
The final answer is age, height, sex, and sometimes ethnicity are the parameters entered into the PFT computer to calculate predicted values.
Answer for screen readers
The final answer is age, height, sex, and sometimes ethnicity are the parameters entered into the PFT computer to calculate predicted values.
More Information
Pulmonary function tests use these demographic factors to account for biological variability in lung function. This allows the comparison of an individual's results with a predicted 'normal' value.
Tips
Common mistakes include omitting one of these demographic factors, especially ethnicity if it is required for specific reference equations.
