WebMeasuring Lung Capacity with Spirometry Spirometry is a simple, noninvasive breathing assessment that can be used to determine overall lung health. During a spirometry assessment, an individual will inhale and exhale through a device called a spirometer. The spirometer will measure the volume of air that is passed through a sensor.

WebPulmonary function testing is a group of tests that provide objective data on a patient's lung function. These tests must be interpreted within the context of the patient's history and physical examination, though their patterns can suggest different categories of respiratory disease.

As per Boyle’s law, a decrease in lung volume results in an increase in the pressure within the lungs. The pressure inside the lungs is now greater than in the external environment, meaning air moves out of the lungs down the pressure gradient. the waterboys fisherman\u0027s blues chords
