Respiratory distress

The other symptom of the cardiopulmonary phase of hantavirus is respiratory distress. Along with hypotension, these symptoms usually last 48 hours to 7 days. In the majority of cases, the onset of the cardiovascular and respiratory symptoms will be preceded by dry cough. They appear suddenly in the patient and may lead to cardiovascular collapse as mentioned above. The capillaries constantly leak plasma to the pulmonary vascular bed, causing severe pulmonary edema. This pulmonary liquid hinders the exchange of oxygen and carbon dioxide in the lungs, and patients feel the urge to breathe rapidly and more profoundly to compensate. In the clinical exam, patients will likely have crackles and decreased breath sounds.
