2) and can happen in individuals with severe airway obstruction [63,65,66,71]. The relationship between FIVC, SVC and FVC remains to be studied in mildly obstructed patients, but the ability to detect air trapping and potentially small airway changes may be useful in identifying early steps ...
ObjectiveTo explore the application potential of forced expiratory volume in three second/forced vital capacity (FEV3/FVC) in early lung diseases, such as early airway obstruction and mild gas trap.MethodsA total of 288 patients (excluding those with restrictive ventilation dysfunction) who underwent...

Childhood measles on its own did not increase the risk of airflow obstruction in mid-adult life, but did appear to influence the impact of asthma and smoking. A three-way interaction between measles, asthma and smoking found that the combination of heavy smoking (over 10 pack years) and ...
Critically ill patients with COPD exacerbations who require endotracheal intubation present with dynamic hyperinflation, which may result from numerous factors, including reduced lung recoil pressure, small airway collapse, airway inflammation, mucus overproduction and reduced clearance, and varying degrees of...
These indices confirm the presence of moderate airflow obstruction, small airways dysfunction, and a prolonged expiratory phase during the forced expiratory manoeuvre. Post-bronchodilator spirometry showed partially reversible airflow obstruction with an increase in FEV1 of only 8%, much less than the ...
Airway obstruction correlates with collagenase-2 (MMP-8) expression and activation in bronchial asthma. Lab. Invest. 82, 1535–1545. https://doi.org/10.1097/01.lab.0000035023.53893.b6 (2002). Article CAS PubMed Google Scholar Yadama, A. P., Mirzakhani, H., McElrath, T. F., Litonjua...
Post-extubation excitement and restlessness, sometimes attributed to pain, may lead to the addition of opioids to the PCIA pump, which can impair respiratory control and upper airway function, causing central apnea, airway obstruction, and hypoxemia. This risk is particularly pronounced in patients ...
