31 Normal Asthma Asthma is a chronic inflammatory disorder of the airways This bronchoscopic view of an airway shows the normal appearance of a healthy airway, contrasted with inflammation (reddening and swelling) and narrowing of the asthmatic airwayMicroscopic examination of biopsy and lavage samples taken through the bronchoscope has established that inflammatory changes are present in asthma of all grades of severity, including recently diagnosed asthma
36 Air trapping Normal Hyperinflation Air trapping affects patients with COPD.It results in an expansion of the chest wall, which places the respiratory muscles at a mechanical disadvantage.1Air trapping limits the ability of patients to expand tidal volume when required; for example, during activity. This makes the patient feel breathless or dyspneic.Hyperinflation, resulting from air trapping, can be observed on standard X-rays.Note the wide intercostal spaces in this patient with COPD, which are caused by air trapping.O'Donnell DE, Webb K.
