The novel coronavirus can cause pneumonia, and the virus is relatively easy to inactivate because it is less tolerant to ultraviolet light and heat, and more afraid of 75% alcohol and chlorinated disinfectants or strong oxidizers. If pneumonia is triggered, patients with pneumonia are very sensitive to hypoxia, and if they are in a state of oxygen deprivation they will be very uncomfortable, so they need to be in an oxygen-enriched state and need to get their lungs moving and have the patient take deep breaths appropriately. Therefore, when the new coronavirus pneumonia has been rescued, the patient should be encouraged to breathe more, once the lungs can not move will trigger respiratory distress, which can trigger respiratory failure.
