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) Good start (back extrapolation < 5% of FVC or 150 mL)
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.
Flow-volume curves: Graph of airflow as a function of volume during inhalation and exhalation. Volume-time curve: Graph of the volume exhaled over time. Spirometry is the simplest pulmonary function test. For example, it may be obtained in the office of some primary care physicians.
9 paź 2024 · Pulmonary function testing (PFT) is a series of non-invasive tests that measure how well the lungs are functioning. These tests evaluate lung volume, capacity, rates of flow, and gas exchange, helping to diagnose and monitor respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and restrictive lung diseases.
1 Introduction 1 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-
5 cze 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.
29 sie 2024 · Pulmonary Function Testing (PFT) is instrumental in evaluating numerous respiratory conditions, encompassing obstructive and restrictive lung diseases. It serves to monitor the evolution of diseases and ascertain the efficacy of administered treatments.
