The maximum amount of air a person can exhale forcefully after taking a deep breath
What does the Forced Expiratory Volume in 1 second (FEV1) measure in spirometry?
The amount of air forcibly exhaled in the first second during the FVC test
What does the FEV1/FVC ratio help determine in spirometry?
If there is an obstruction to airflow

What are the key measurements obtained from spirometry?
Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), FEV1/FVC ratio, Peak Expiratory Flow (PEF)
What is the main cause of transudative fluid accumulation?
Increased hydrostatic pressure or decreased oncotic pressure in the blood vessels
What is the composition of transudate?
Low protein content and is an ultrafiltration of plasma
What causes exudative fluid accumulation?
