Can informing a patient of the results of spirometry testing increase awareness of the harmful effects of smoking?

What are spirometry tests and why are they performed? Learn about the procedure, how the results are read, and what other testing methods may be available.

Spirometry results depict only the pattern of ventilation, which may be normal, obstructive, restrictive, or mixed. The diagnosis should be based on both clinical features and spirometry results.

It is one of the main risk factors for vascular and respiratory diseases and a causative agent for chronic obstructive pulmonary disease (COPD), accelerating the physiological worsening of the ...

Following use of race-neutral vs. -specific lung function equations, spirometry findings and patterns differed, especially among Black children/adolescents, according to results published in JAMA ...

Similarly, it would reclassify most Black children with dysanapsis as having an obstructive pattern, leading to an escalation in asthma care or further testing, they added.

As it is an effort-dependent test, spirometry is best performed when the patient is well. It shows a pattern of airflow and lung volumes rather than the disease. The patterns can be: Normal; ...

Spirometry scores tell doctors how much air you’re able to pull into your lungs and how quickly you can expel it. This test is helpful for diagnosing and treating breathing conditions like COPD.

Equations that don’t use racially and ethnically adjusted spirometry results to help determine eligibility for chronic obstructive pulmonary disease (COPD) clinical trials may lead to higher ...

Spirometry is a type of pulmonary function test that provides information about the function of the lungs and can be used for a variety of purposes.
