Baltimore: Williams & Wilkins, 1986. Harrison's Principles of internal medicine. Rubenstein E, Federman DD, eds. This reflects the interaction between chemical and neural influences on breathing.2,3. A family history of asthma, lung problems (e.g., chronic bronchitis, bronchiectasis, serious pulmonary infections), allergies or hay fever must also be considered.9. Pulse oximetry uses an infrared light source to determine the hemoglobin oxygen saturation. Fashion Trends. At very mild degrees of airway obstruction, the sensation of chest tightness predominates. Mahler DA. To perform the test, most patients require specific demonstration of the appropriate technique and coaching during the test in order to produce a maximal effort. Other causes of interstitial disease include farmer's lung and other pneumoconioses, infiltrating malignancy, fibrosis due to side effects of some medications (e.g., some chemotherapeutic agents, amiodarone [Cordarone]) and idiopathic interstitial fibrosis, which constitutes the largest single category of interstitial lung disease.9.
