Inspiratory flow-volume curve evaluation for detecting upper airway disease.
BACKGROUND The 2005 American Thoracic Society/European Respiratory Society guidelines on spirometry emphasize examination of the inspiratory curve of the flow-volume loop for evidence of intrathoracic or extrathoracic upper airway obstruction. We sought to determine how frequently evaluations are performed for abnormal inspiratory curves. METHODS We retrospectively reviewed all examinations p...
متن کاملThe Relationship between the Severity of Airway Obstruction and COPD Diagnostic Questionnaire Score in COPD Patients
Background & objectives: Chronic obstructive pulmonary disease (COPD) is characterized by irreversible airflow limitation and systemic inflammation which is also associated with pulmonary and extra-pulmonary complications. COPD Diagnostic Questionnaire (CDQ) is a valid questionnaire that is used to identify patients with COPD. The purpose of this study was to determine the relationship between ...
متن کاملRelationship between spontaneous expiratory flow-volume curve pattern and air-flow obstruction in elderly COPD patients.
BACKGROUND Assessment of the degree of air-flow obstruction is important for determining the treatment strategy in COPD patients. However, in some elderly COPD patients, measuring FVC is impossible because of cognitive dysfunction or severe dyspnea. In such patients a simple test of airways obstruction requiring only a short run of tidal breathing would be useful. We studied whether the spontan...

متن کاملControl of extrathoracic airway dynamics.
The ventilatory controlling factors associated with oral augmentation of nasal breathing were investigated in 25 (14 women, 11 men) healthy adults during an incrementally graded bicycle exercise test. Ventilatory variables were measured by separate oral and nasal pneumotachometers integrated with a valveless oral-nasal face mask and a flexible oral catheter. Inspired and expired breath length, ...
