Spirometry: What to expect
The oxygen levels in the blood may be tested using a pulse oximetry test.
Spirometry is the simplest and most widely used pulmonary function test, but other tests may be needed to make a final diagnosis.
Lung volume tests are the most accurate measurement of lung capacity.
They measure the total lung volume and are done with the person sitting in a small, sealed room with clear walls, where changes in pressure inside enable lung volume to be determined.
Lung diffusion capacity determines how well oxygen gets into the blood from inhaled air, using a gas mixture that contains 0.3 percent carbon monoxide (CO).
Spirometry test cost
The amount of CO left in the exhaled air demonstrates how well the person can absorb gas.
The breathing done in this test is less intense than in a spirometry test, but it can take longer. Blood may also be tested to find the level of hemoglobin it contains.
Hemoglobin affects oxygen absorption.
Pulse oximetry provides an estimate of oxygen levels in the blood by putting a probe on the skin’s surface.
