Significant bronchodilator response fev1
WebThe bronchodilator test plays a crucial role in the management of COPD, eg, the diagnosis of COPD is confirmed in cases with FEV1/FVC ratios below 0.7 after bronchodilator administration. Flow response after bronchodilator inhalation is universally and frequently used as an indicator for assessing responsiveness in general practice. WebEstablishing the definition of a significant spirometric response to bronchodilator is a controversial issue (1–4).The 2005 American Thoracic Society/European Respiratory Society (ATS/ERS) guidelines recommend that a significant response be defined as a 12% and … Establishing the definition of a significant spirometric response to bronchodilator … We would like to show you a description here but the site won’t allow us.
