Alveolar hemorrhage can cause respiratory dysfunction and can even be life-threatening. Tracheal intubation or tracheotomy mechanical ventilation must be taken promptly, and some hemostatic drugs such as vitamin K1 and hemagglutinin can also be used to control bleeding, adjust and manage as soon as possible. Alveolar hemorrhage is usually caused by acute left heart failure, pulmonary lesions caused by tuberculosis, which can contain nitrates and thus relieve the symptoms of left heart failure. Patients can use rifampin, isoniazid, ethambutol, bixinamide, streptomycin and other drugs to treat tuberculosis. Keeping the room air fresh and dry and circulating to reduce the growth of bacteria can be alleviated by combining labor and rest.
