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.
The main function of our respiratory system is to provide the body with a constant supply of oxygen and to remove carbon dioxide. To achieve these functions, muscles and structures of the thorax create the mechanical movement of air into and out of the lungs called ventilation.
Pulmonary function tests (PFT’s) are breathing tests to find out how well you move air in and out of your lungs and how well oxygen enters your blood stream. The most common PFT’s are spirometry (spy-RAH-me-tree), difusion studies, and body plethysmography (ple-thiz-MA-gra-fee).
15 Ιουλ 2024 · This Printable PFT Interpretation Chart is a roadmap for decision-making once you have your patient’s pulmonary function test results. To ensure you’re following the flowchart correctly, go through the steps below: Step 1: FEV₁ / VC ratio.
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.
Functional Residual Capacity (FRC): the volume of air remaining in the lungs at the end of a normal tidal expiration (3 L). Inspiratory Capacity (IC): The volume of air that is inhaled into the lung during a maximal forced inspiration effort that begins at the end of a normal tidal expiration (VT+IRV=3L).
