Spirometry

When working with spirometry, a standardized test that measures how much air you can inhale and exhale, and how quickly you can do it. Also known as pulmonary function testing, it helps doctors spot airway problems early and track disease progression.

How Spirometry Connects with Everyday Respiratory Care

One of the key lung function test, spirometry provides metrics like FEV1 and FVC that reveal airway obstruction is essential for diagnosing COPD, a chronic disease marked by reduced airflow and persistent cough. Doctors also rely on spirometry to confirm asthma, a condition where airways tighten in response to triggers. The test often follows a bronchodilator challenge, where a medication is given to see if lung capacity improves—information that guides treatment choices. By comparing pre‑ and post‑medication values, clinicians can decide whether inhalers or other therapies will work best.

Beyond formal testing, patients might use a peak flow meter, a portable device that records the highest speed of exhaled air at home. While it doesn’t replace spirometry, it offers daily snapshots that help track asthma control or COPD flare‑ups. Understanding the difference between FEV1 (the volume exhaled in one second) and FVC (total exhaled volume) is crucial; a low FEV1/FVC ratio typically indicates obstructive disease, while a normal ratio with reduced volumes points to restrictive patterns. These numbers shape decisions about pulmonary rehab, oxygen therapy, and lifestyle adjustments.
