**Pulmonary Function Test and Bronchodilator Response**

**Question:**

Describe what you think would happen to the Pulmonary Function test if someone with obstructive pulmonary disease is given a bronchodilator?

Specifically, what do you think would happen to FEV1?

**Explanation:**

When a person with obstructive pulmonary disease, such as asthma or chronic obstructive pulmonary disease (COPD), is administered a bronchodilator, the medication helps to relax and open the airways in the lungs. This is expected to lead to an improvement in pulmonary function test results.

### Key Effects on Pulmonary Function Test:

- **Increase in FEV1 (Forced Expiratory Volume in 1 second):** 
  - The bronchodilator is likely to increase the FEV1, which measures the amount of air a person can forcefully exhale in one second. This improvement indicates that the airways are less constricted following medication administration.

- **Improvement in FEV1/FVC Ratio:**
  - The ratio of FEV1 to FVC (Forced Vital Capacity) may also improve, indicating better airflow and reduced obstruction in the airways.

These changes depend on the severity of the disease and how responsive the airways are to the treatment.
