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. Identify obstructive, restrictive, mixed obstructive-restrictive and pulmonary vascular patterns of ...
5 Ιουν 2012 · In this article we will provide an overview of basic pulmonary function tests and an algo-rithm for using and interpreting them, and then we use three cases to explain how to use these tests to identify the pattern of respirato-ry dysfunction, then make the diagnosis.
The first three editions of Interpretation of Pulmonary Function Tests were well received and met our goal of appealing to a wide, varied audience of health professionals.
Interpretation of PFTs is usually based on comparisons of data measured in an individual patient or subject with reference (predicted) values based on healthy subjects.
PEF is the highest velocity of air&ow that can be transiently achieved during a maximal expiration from total lung capacity. Because &ow is a function of resistance, and the majority of resistance is encountered in the upper airways, the peak &ow is an excellent indicator of large airway function.
LUNG VOLUMES & CAPACITIES: Tidal Volume (VT):The volume of air entering the nose or mouth per breath (500 ml). Residual Volume (RV): The volume of air left in the lungs after a maximal forced expiration (1.5L).
