Screening spirometry & flow-volume curve 中文
WebJun 6, 2014 · Spirometry quality assurance includes examination of test values and evaluation of both the volume-time and flow-volume curves for evidence of technical errors. Technically poor spirometry may have little value and may even provide misleading information. When erroneous curves are detected, additional maneuvers are often needed.

Further, the performance of... WebThe inspiratory flow-volume (FV) curve can be used to identify patients with upper airway obstruction, air trapping, and restriction. Current computed pulmonary function testing equipment often mandates a forced expiratory maneuver (FEM) immediately prior to the forced inspiratory maneuver (standard method). We evaluated the inspiratory FV curve …
WebSep 22, 2024 · With the classical spirometer, the patient forcibly exhales into the machine; the peak expiratory flow rate and the shape of the expiratory flow-volume curve is therefore the best measure of airway resistance.

WebFeb 1, 1973 · The flow-volume loop is a test of ventilatory function in which a graphic recording of maximal flow rates is displayed at all lung volumes during a maximal effort forced expiratory and inspiratory vital capacity maneuver. The test is easy to demonstrate, administer, and analyze. Pulmonary diseases produce characteristic flow-volume loop … WebJun 8, 2015 · Spirometry This is a physiological test which measures respiratory performance as a function of time and volume, which therefore incorporates flow (as flow is volume over time). Conventionally, this test is performed in the following manner: The patient inhales to TLC
