经鼻持续气道正压通气 (nasalcontinuouspositiveairwaypressure ,NCPAP)设备简单 ,操作容易 ,副作用少 ,已广泛应用于新生儿和小婴儿呼吸衰竭的治疗。NCPAP的不足是狭小的鼻塞内径加大了气道阻力 ,增加患儿的呼吸功。为此 ,Moa等[1]对鼻塞 (以下简称Moa鼻塞 )进行了改进 ,并在 Nasal continuous positive airway pressure (Nasal continuous positive airway pressure, NCPAP) device is simple, easy to operate, fewer side effects, has been widely used in neonatal and small infant respiratory failure treatment. The inadequacy of NCPAP is that the narrow nasal obstruction increases the airway resistance and increases the breathing work of children. To this end, Moa et al [1] on the stuffy nose (hereinafter referred to as Moa stuffy nose) has been improved, and
