Pulmonary Function Tests Podcast
These tests assess lung volumes, capacities, rates of flow, and gas exchange. Different procedures measure lung function in different ways.
Peak Flow Measurement Podcast
Peak flow measurement is a procedure that records the amount of air flowing out of your lungs. Peak flow can be measured with either a spirometer or a peak flow meter.
For the oximetry test, a clip-like probe is placed on one of your fingers or on an ear lobe to measure the amount of blood that's saturated with oxygen. Your health care provider uses this test to find out if you need supplemental oxygen.
