How do I perform a spirometry with reversibility?

Performing a spirometry test with reversibility involves a few additional steps to assess how your lung function responds to a bronchodilator medication, typically a short-acting beta-agonist. Here’s a general guide on how to perform a spirometry test with reversibility:

Before the Test:

1. Find a comfortable place to sit with your feet flat on the floor and sit up straight.
2. Relax and take a few normal breaths.

Baseline Spirometry:

1. Inhale deeply, filling your lungs with as much air as you can.
2. Place the mouthpiece of the spirometer gently in your mouth, making sure it’s sealed around your lips.
3. Exhale forcefully into the spirometer until your lungs are completely empty. This is your first measurement.
4. Rest a bit and then repeat two more measurements.

Taking Your Inhaler:

1. Your healthcare provider will give you instructions on which medication to use.
2. Follow your healthcare provider’s instructions for using the inhaler. It usually involves taking a deep breath and inhaling the medication.
3. Wait for the recommended time (usually about 15-20 minutes) for the medication to work.

Post-Bronchodilator Spirometry:

1. After waiting, your healthcare provider will ask you to repeat the spirometry test.
2. Follow the same steps as the first test: take a deep breath, use the mouthpiece, and exhale forcefully into the spirometer.
3. Again, you should perform 3 tests in total after you’ve used the bronchodilator.

Understanding the Results:

1. Your healthcare provider will compare the spirometry measurements: the ones before taking the inhaler (baseline) and the ones after (post-bronchodilator).
2. They’ll assess if there’s a significant improvement in lung function after using the inhaler. Usually, they look for a 12% or 200 mL increase in your Forced Expiratory Volume in 1 Second (FEV1).

What’s Next:

1. Your healthcare provider will discuss the results with you and determine the best course of action based on the changes in lung function.
2. They’ll adjust your treatment plan as needed to help manage your respiratory condition effectively.

Remember, always follow your healthcare provider’s instructions during this test, and don’t hesitate to ask questions if you’re unsure about anything.
