People with COPD experience a more rapid decline in what is called forced expiratory volume, or FEV. FEV is the maximum volume of air that can be exhaled within a specified time period, starting from maximal inhalation. A subscript indicates the time period in seconds. For example, FEV1is th...
With COPD-6 device, values of S and SP are considerably lower than with the Piko-6, so that the most appropriate cut-point of FEV1/FEV6 is <0.78. In tables 1 and 2 are exposed the values of S, SP, negative and positive predictive values, positive and negative likelihood ratios, and...
advanced COPD. Lung transplantation, although effective in selected patients for palliation of symptoms and improving survival, is limited by donor organ availability and economic constraint. Reconditioning marginal organs previously declined for transplantation with ex vivo lung perfusion (EVLP) is one po...
The Global initiative for chronic Obstructive Lung Disease (GOLD) report is revised annually and released each November in parallel with World COPD Day. The 2025 GOLD report has incorporated multip...
Endobronchial coils is an alternative endoscopic therapy among patients with COPD regardless of collateral ventilation status. Other endoscopic therapies for patients with COPD are still in the pilot stages of evaluation and are not meant for routine practice in the current state.Introduction...
TUESDAY, July 9, 2019 (HealthDay News) -- Use of a threshold of airflow obstruction of forced expiratory volume in one second:forced vital capacity (FEV1:FVC) of 0.70 discriminates chronic obstructive pulmonary disease (COPD)-related hospitalization and mortality, according to a study published ...
Despite significant global reductions in cases of pneumonia during the last 3 decades, pneumonia remains the leading cause of post-neonatal mortality in ch
The lungs are the organs that humans use to breathe in air. They operate to take oxygen out of the air and send it to the cells in the body through the bloodstream.Answer and Explanation: Pneumothorax is a condition that can cause a lung to collapse. This occurs when air collects ...
According to current recommendations, a clinical diagnosis of COPD is primarily based on the detection of airflow obstruction in spirometric measures.1,2 However, the spirometric criteria defining ...
The study of pulmonary functions tests and fat distribution in overweight and obese adult males The values of Forced Expiratory Volume in first second (FEV1) less than 80% of the expected value and ratio of forced expiratory volume in first second to the forced vital capacity less ([FEV.sub....
