Review age, gender, smoking status, BMI, indication, flow-volume curves. Quality control. Three acceptable maneuvers with repeatable values: Two highest values of FVC and FEV1 should be within 150mL (100mL if FVC ≤ 1L)
Describe the clinical indications for pulmonary function testing. Understand the physiology of the core pulmonary function tests: spirometry, lung volumes and DLCO. Apply an organized approach to interpreting pulmonary function tests.
Pulmonary function tests can provide important clinical information, yet they are vastly underused. They are designed to identify and quantify defects and abnormalities in the function of the respiratory system and answer questions such as the following: How badly impaired is the patient’s lung function? Is air-way obstruction present?
• See if you have any lung disease. • Measure the severity of lung disease. • To see if medication will make your breathing better. • To test your lungs before an operation. What are the benefits and alternatives? Your doctor will use the information from the investigations to start, stop or modify your treatment.
1 sty 2020 · This chapter provides a structured approach to analyzing and interpreting the many data points necessary to provide an accurate assessment of normal and abnormal pulmonary function tests.
Pulmonary function tests are designed to measure the volume of air you are able to blow out (exhale), the speed at which you can exhale, the size of your lungs and how well the air that you breathe in is travelling to your blood. There is also a test to see if medication may help relieve your symptoms.
Pulmonary Function Tests Spirometry1,2 Lung volume DL CO (diffusing capacity of the lung for carbon monoxide) • Airflow measurement • Most effective at identifying obstructive defects • Bronchodilator test can be used to measure reversibility and help evaluate asthma and COPD • Cannot measure RV, therefore the FRC and TLC also cannot
