Which pulmonary function tests best differentiate between COPD phenotypes?
We are still at the early phase of finding useful phenotypes in COPD that can guide therapy. However, in a simple sense, "sick patients die." Many phenotypic measurements of severity correlate with mortality in COPD: FEV(1), the ratio of inspiratory capacity to total lung capacity (IC/TLC), diffusing capacity of the lung for carbon monoxide (D(LCO)), 6-min walk distance, and maximum oxygen (O(...
متن کاملUse of cluster analysis to describe desaturator phenotypes in COPD: correlations between pulmonary function tests and nocturnal oxygen desaturation
BACKGROUND Significant heterogeneity of clinical presentation and disease progression exists within chronic obstructive pulmonary disease (COPD). Although forced expiratory volume in 1 second (FEV(1)) inadequately describes this heterogeneity, a clear alternative has not emerged. This article discusses and refines the concept of phenotyping desaturators in COPD and shows a possible pattern whic...
متن کاملPulmonary Function Tests:
Indications for pulmonary function tests (PFTs) have widened substantially, ranging from screening smokers for early lung disease to determining the diagnosis and prognosis of pulmonary conditions. Current indications also include screening for drug-induced lung toxicity and preoperative screening for lung resection surgery. In the workup of respiratory symptoms, such as dyspnea, cough, and whe...
متن کاملPulmonary Function Tests
Pulmonary function tests are valuable investigations in the management of patients with suspected or previously diagnosed respiratory disease. They aid diagnosis, help monitor response to treatment and can guide decisions regarding further treatment and intervention. The interpretation of pulmonary functions tests requires knowledge of respiratory physiology. In this review we describe investig...
متن کاملPulmonary Function Tests (PFT)
Pulmonary function tests (PFT) are a battery of tests that measure lung function and aid in the management of patients with respiratory disease. They are performed using standardized equipment and can be used for diagnosis, prognostication, management and follow-up of patients with pulmonary pathology. Although PFT may not identify the exact pathology, it broadly classifies respiratory disorder...
