Nasal continuous positive airway pressure (Nasal-CPAP) is frequently used in the care for the preterm neonates．I have developed a nasal CPAP device with bypath (BNCPAP) of vertical allocated type with additionally compiled HFOV function. In previous report，I performed the performance test of the BNCPAP device which I produced. In the present report， I perform a performance prediction about 7 calculation models that increased duct exit of model. BN-CPAP device which widened exit duct width lost CPAP pressure increase at expiration, and it became clear to have the new device performance that CPAP pressure decreased for increase of MAP.
