Emergency treatment and therapy for respiratory failure. Type I respiratory failure refers to the lone presence of hypoxemia and absence of hypercapnia, featuring ventilation dysfunctions, blood change of PaO 2 ≤60 mmHg, and PaCO 2 which can be maintained at normal level or reduced (24) . Type I respiratory failure also refers to the coexistence of hypoxemia and hypercapnia, impairment of ventilatory function and gas exchange functions, severe lung lesion, obstruction of trachea and bronchia caused by sticky secretions, blood change of PaO 2 <60 mmHg, and PaCO 2 >50 mmHg. Main clinical manifestations of children patients with type I pneumonia with respiratory failure include, poor mental state or dysphoria, polypnea, cyanosis of lips, dyspnea, nasal flaring and three depression signs. These symptoms are difficult to distinguish from type II respiratory failure, and can be observed only by blood gas analysis, which shows a marked difference between type I and II. Type II respiratory failure shows symptoms of type I respiratory failure and in addition more often than not, it also has symptoms such as shallow breathing, irregular rhythm, slow breathing, drowsiness or coma and even jaw breathing in some patients (25, 26) . In our study, changes in condition and changes in blood were closely observed, and where required, a tracheal intubation ventilator was employed to improve the cure rate.
