The symptoms of organ failure mainly depend on which organ is failing. Because of the different functions of failure, the clinical symptoms are not the same, for example, if the patient is pulmonary failure, most patients will appear wheezing, shortness of breath, coughing, dyspnea, etc., of which dyspnea is the most common clinical symptom, severe respiratory failure patients may be accompanied by some consciousness disorders, vital signs are unstable and so on. The patient is heart failure, the typical symptoms of heart failure patients, if it is left heart failure, there may be dyspnea after activity, oliguria, weakness, dizziness. If the patient is right heart failure, the patient mainly manifests body circulation stasis, and may have a series of problems such as hepatic stasis, pronounced swelling of the lower extremities, ascites, and pleural fluid. If the manifestation of hepatic and renal failure, there will be ascites, the whole body has skin and sclera yellow staining, and there will be oliguria or anuria, generalized edema and other symptoms. Therefore, clinically, there are definitely differences in the manifestation of clinical symptoms for different organ failures, and they should be treated differently.
