The document discusses lung disease and pulmonary embolism. For lung disease, it describes how hypoxemia and hypercapnia can lead to pulmonary hypertension, increased workload on the right ventricle, right heart enlargement and failure. Symptoms include those of the underlying lung disease and right heart failure. Management focuses on improving ventilation, treating the underlying lung disease, and managing heart manifestations.
For pulmonary embolism, it describes how blood clots can obstruct pulmonary arteries, causing hypoxemia, hypertension, right ventricular failure and shock. Symptoms include dyspnea, tachycardia and chest pain. Diagnosis involves tests like ventilation/perfusion scans and angiography. Treatment focuses on emergency management, antico
