What is the difference between respiratory failure and acute respiratory distress?

Respiratory failure differs from acute respiratory distress syndrome in terms of definition, etiology, clinical manifestations and treatment. Respiratory failure differs from acute respiratory distress syndrome in the following aspects: 1. Different definitions:

Respiratory failure is a serious disorder of pulmonary ventilation and (or) ventilation caused by various reasons, so that effective gas exchange cannot be carried out, resulting in hypoxia accompanied (or not accompanied) by carbon dioxide retention, thus causing a series of clinical syndromes of physiological function and metabolic disorder. Acute respiratory distress syndrome is a clinical syndrome characterized by alveolar capillary injury after severe infection, trauma, shock and other diseases inside and outside the lung, belonging to the severe stage of acute lung injury. The common causes of acute respiratory distress syndrome include severe infection, trauma, shock, aspiration, inhalation of toxic gases, acute pancreatitis, etc. The clinical manifestations of acute respiratory distress syndrome mainly include shortness of breath, dyspnea, refractory hypoxemia, lung imaging changes, etc. 4. Different treatment methods: The treatment methods of respiratory failure mainly include oxygen therapy, mechanical ventilation, anti-infection, correction of acid-base balance imbalance and electrolyte disorder. Acute respiratory distress syndrome treatment methods mainly include mechanical ventilation, fluid management, anti-infection, nutritional support, etc. In short, respiratory failure and acute respiratory distress syndrome are serious diseases of the respiratory system, but their etiology, clinical manifestations and treatment methods are different. In clinical practice, comprehensive judgment and treatment are needed according to the specific conditions of patients.
