How do you classify COPD severity?
These results have four grades, too:
- GOLD 1: Mild.
- GOLD 2: Moderate.
- GOLD 3: Severe.

What is the best indication of severity of COPD?
The diagnosis of chronic obstructive pulmonary disease (COPD) should be suspected in patients with risk factors (primarily a history of smoking) who report dyspnea at rest or with exertion, chronic cough with or without sputum production, or a history of wheezing.
How does Spirometry indicate COPD?
Spirometry is a method of assessing lung function by measuring the volume of air that the patient can expel from the lungs after a maximal inspiration. The indices derived from this forced exhaled maneuver have become the most accurate and reliable way of supporting a diagnosis of COPD.
What should a spirometry reading be?
In general, your predicted percentages for FVC and FEV1 should be above 80% and your FEV1/FVC Ratio percentage should be above 70% to be considered normal. However, the information provided in these spirometry results can be used in many additional ways.
What is abnormal spirometry?
An “abnormal” FVC could be due to restrictive or obstructive lung disease, and other types of spirometry measurements are required to determine which type of lung disease is present.
How to interpret spirometry results?
Interpreting spirometry results. A mean (mid) value is used as the reference value when interpreting results but there are upper and lower levels of normal values; lung volumes of 80-120%
How to take a spirometry test?
Spirometry is a standard test doctors use to measure how well your lungs are functioning. The test works by measuring airflow into and out of your lungs. To take a spirometry test, you sit and breathe into a small machine called a spirometer. This medical device records the amount of air you breathe in and out and the speed of your breath.
How is COPD diagnosed?
Spirometry is a simple, non-invasive test that is used to diagnose COPD. When you take the test, you will be asked to blow all the air out of your lungs into a mouthpiece connected to a machine known as a spirometer.
