Reflections on the Application of Critical Care Ultrasound in Viral Pneumonia Patients with Circulatory Dysfunction-New Classification and Precision Treatment Based on Ciritical Care Ultrasound

Viruses are among the main pathogens of pulmonary infection and tend to cause pandemics of viral pneumonia. Severe viral pneumonia tends to be accompanied by acute respiratory distress syndrome (ARDS) manifestations, displaying highly specific clinical symptoms that are most prominently expressed in the circulatory system. Shock occurred rarely, it occured at a rather late stage in this outbreak of viral pneumonia. However, because of the extensive use of critical care ultrasound, we have a deeper understanding of the characteristics of acute circulatory disorder caused by severe viral pneumonia, prompting us to reflect more thoroughly about circulatory disorders caused by other types of infections. In general, acute circulatory disorder is not uncommon in severe viral pneumonia in this outbreak, and is characterized by vascular damage, volume disorder and cardiac abnormalities of three types, high stress state, acute right ventricular dysfunction and diffuse cardiac inhibition. In the case of poor management
