cracklessoft, high-pitched, discontinuous popping sounds during inspiration caused by delayed reopening of the airways
dyspneasubjective experience that describes difficulty breathing; shortness of breath
egophonyabnormal change in tone of voice that is heard when auscultating the lungs
fremitusvibrations of speech felt as tremors of the chest wall during palpation
hemoptysisexpectoration of blood from the respiratory tract
hypoxemia decrease in arterial oxygen tension in the blood
hypoxiadecrease in oxygen supply to the tissues and cells

orthopneainability to breathe easily except in an upright position
oxygen saturationpercentage of hemoglobin that is bound to oxygen
physiologic dead spaceportion of the tracheobronchial tree that does not participate in gas exchange
pulmonary diffusionexchange of gas molecules (oxygen and carbon dioxide) from areas of high concentration to areas of low concentration
pulmonary perfusionblood flow through the pulmonary vasculature
respirationgas exchange between atmospheric air and the blood and between the blood and cells of the body
rhonchilow-pitched wheezing or snoring sound associated with partial airway obstruction, heard on chest auscultation
stridorharsh high-pitched sound heard on inspiration, usually without need of a stethoscope, secondary to upper airway obstruction
