You test a patient Pre BD (before bronchodilator) and their actual % is 60%. You repeat with BD (after bronchodilator) and the actual % is 74%. What does this mean?

A) The patient has a 14% improvement in lung function with bronchodilators.
B) The patient has a 14% decrease in lung function with bronchodilators.
C) The patient has a 60% improvement in lung function with bronchodilators.

Final answer:

The patient has a 14% improvement in lung function with bronchodilators.

Step-by-step explanation:

The FEV1/FVC ratio is used to diagnose lung diseases including asthma, emphysema, and fibrosis.

If the FEV1/FVC ratio is high, the lungs are not compliant (meaning they are stiff and unable to bend properly), and the patient most likely has lung fibrosis. Conversely, when the FEV1/FVC ratio is low, there is resistance in the lung that is characteristic of asthma.

In the given scenario, the actual % of lung function before bronchodilator is 60%, and after bronchodilator, it is 74%. This means that the patient has a 14% improvement in lung function with bronchodilators.

Therefore, the correct answer is A) The patient has a 14% improvement in lung function with bronchodilators.
