呼吸衰竭是新生儿多种疾病危重的表现之一。任何原因引起呼吸器官的通气功能或/和换气功能不足,导致严重的低氧血症及二氧化碳潴留,临床表现为吸气性凹陷,呼吸频率>70次/分,发绀(用氧气不能缓解)或顽固性呼吸暂停。血气分析:P_aO_2<50mmHg(6.7KP_a),P_aCO_2>50mmHg(6.7KP_a),pH<7.25者可诊断为新生儿呼吸衰竭。新生儿呼吸功能障碍及导致的呼吸衰竭,是死亡的重要因素之一。樊友煜等曾作354例危症新生儿预后分析,其中住院死亡
Respiratory failure is one of the critically ill manifestations of many newborns. Ventilation and / or ventilatory insufficiency of respiratory organs for any reason, leading to severe hypoxemia and carbon dioxide retention. The clinical manifestations are aspiration depression, respiratory rate> 70 beats / min, cyanosis (can not be relieved with oxygen) Or refractory apnea. Blood gas analysis: P_aO_2 <50mmHg (6.7KP_a), P_aCO_2> 50mmHg (6.7KP_a), pH <7.25 can be diagnosed as neonatal respiratory failure. Neonatal respiratory dysfunction and respiratory failure, is one of the important factors of death. Fan Youyu et al have made 354 cases of neonatal crisis prognosis analysis, in which hospitalized
