Treatment in the remission phase: mainly for the treatment of the primary disease, including improving the ventilation of the lungs, and rehabilitation exercises need to be given. It is recommended to give inhaled hormone therapy and long-term oxygen therapy. 2. Acute treatment: For cardiac insufficiency in acute attack state, it is necessary to control respiratory infection and other triggers, improve respiratory function, rescue respiratory failure, give non-invasive positive pressure ventilation, and if necessary, perform tracheotomy, tracheal intubation, mechanical assisted ventilation and other treatments.
