Airspaces - Study guides, Class notes & Summaries

Emphysema Pathophysiology ~~~ Emphysema is a pathologic diagnosis defined by permanent enlargement of airspaces distal to the terminal bronchioles. This leads to a dramatic decline in the alveolar surface area available for gas exchange. Furthermore, loss of alveoli leads to airflow limitation by 2 mechanisms. First, loss of the alveolar walls results in a decrease in elastic recoil, which leads to airflow limitation. Second, loss of the alveolar supporting structure leads to airwa...

What conditions are the abnormal heart sounds S3 and S4 associated with, respectively? A. S3 = MI or HTN; S4 =CHF B. S3 = Tracheal Stenosis; S4 = Asthma C. S3 = closure of Mitral and Tricuspid Valves; S4 = Closure of Pulmonary Valves D. S3 = CHF; S4 =MI or HTN - Answer Feedback Correct Answer - D S3 is heard in early diastole (after S2) and is associated with CHF. S4 is heard in late diastole (before S1) and is associated with an MI or hypertension. A chronic smoker diagnosed with C...
