Abstract
Nasal continuous positive airway pressure (Nasal-CPAP) is frequently used in the care for the preterm neonates to recruit and maintain the lung volume. The authors have developed Nasal-CPAP device with a bypath type (B-NCPAP) of horizontal type which reduces the breathing work for the neonate. Although we uses it in face up and abdominal position in clinical treatment, a vertical type is more desirable. The fundamental features of B-NCPAP device was tested experimentally. Results show that pressure falls at the time of expiration, and the present device provides a comfortable situation to patient, when it works in inspiration phase especially.
