The document describes pulmonary edema and congestive heart failure. Pulmonary edema is an abnormal accumulation of fluid in the lungs, causing anxiety, suffocation, pale skin, and noisy breathing. Diagnosis involves lung auscultation and chest x-ray. Treatment includes oxygen, diuretics, morphine, and positioning the patient. Congestive heart failure occurs when the heart cannot supply enough oxygen to tissues, causing hypoxia, low blood pressure, crackles, and decreased urine output. It is diagnosed using a pulmonary artery catheter and treated with vasodilators, diuretics, inotropic medications, and balloon pumps while monitoring the patient's condition.
