What is considered a significant change in annual spirometric results? What factors might account for changes in annual spirometry?
Spirometry that is performed annually, usually once a year, to measure lung function is referred to as annual spirometry. In order to perform the test, one must inhale deeply and then forcibly exhale as much air as they can into a spirometer, a machine that measures several aspects of lung volume and airflow.
The following important variables are assessed during annual spirometry:
1) Forced Vital Capacity (FVC): This gauges how much air a person can forcibly expel after inhaling deeply.
2) The Forced Expiratory Volume in One Second (FEV1) test evaluates how much air a person can forcefully expel in the first second.
3)To determine how much air a person can exhale in the first second in relation to their entire lung capacity, one uses the FEV1/FVC ratio. It aids in the diagnosis and classification of lung illnesses like restrictive and obstructive lung diseases.
Spirometry is frequently performed each year to check on lung health, especially in people with long-term respiratory diseases like asthma. It aids medical professionals in monitoring changes in lung function over time, evaluating the efficacy of treatment, and spotting early indications of deteriorating lung diseases.
