Pulmonary edema is fluid accumulation in the lungs. It leads to impaired gas exchange and may cause respiratory failure. It is due to either failure of the heart to remove fluid from the lung circulation or a direct injury to the lung parenchyma. Treatment depends on the cause but focuses on maximizing respiratory function and removing the cause.
Signs and symptoms.
Symptom of pulmonary edema include difficulty breathing, coughing up blood, excessive sweating, anxiety and pale skin. If left untreated, it can lead to coma and even death. These include nocturia (frequent urination at night), ankle edema (swelling of the legs), orthopnea (inability to lie down flat due to breathlessness) and paroxysmal nocturnal dyspnea (episodes of severe sudden breathlessness at night).
