If the child is combined with respiratory failure, it is necessary to try to keep the room ventilation and room humidity appropriate, to turn over regularly, pat the back, and try to keep the child in a semi-sitting position, in order to help sputum discharge and recovery from the disease. Children on invasive ventilators can only lie down, and the bed can be raised appropriately to keep the child in prone position as much as possible to reduce the pressure on the heart, alleviate the symptoms of respiratory distress, and improve the ventilation and air exchange function of the lungs. Moreover, since most of the children will have poor appetite, reduced digestive enzymes and weaker digestive function, it is recommended to choose liquid or semi-liquid diet.
