Spirometry is an important test that helps us understand how well our lungs work. It measures different things about our breathing. Here are the main parts you will see in a spirometry test:
Forced Vital Capacity (FVC): This tells us the total amount of air a person can push out forcefully after taking a deep breath. It shows how much air someone can move and can help doctors find issues related to restrictive lung disease if the amount is lower than normal.
Forced Expiratory Volume in 1 second (FEV1): This measures how much air comes out in the first second when someone forcefully breathes out. It's really important for spotting problems with breathing, like asthma or COPD (chronic obstructive pulmonary disease).
FEV1/FVC Ratio: This ratio helps doctors tell the difference between two types of lung problems: obstructive and restrictive diseases. If this ratio is low (usually less than 70%), it may mean there’s an obstruction. If the ratio is normal but FVC is lower, it might indicate restriction.
Peak Expiratory Flow Rate (PEFR): This measures the fastest speed at which someone can breathe out. It’s helpful in managing asthma, as it helps check how well treatment is working or if symptoms are getting worse.
Lung Volumes: While spirometry mainly measures how air flows, knowing about total lung capacity (TLC), residual volume (RV), and functional residual capacity (FRC) helps us understand overall lung health better.
When we look at all these measurements together, they give a clear view of how the lungs are functioning. This information helps doctors diagnose and keep track of different breathing problems.
