Objective: To study the effect of supine and prone positions on pulmonary function in the term infant with pneumonia.

Methods: Pulmonary function of thirty term infants with pneumonia was tested in the supine and prone positions respectively with Biocore CP-100 Neonatal Pulmonary Function Monitor made by U.S.A.

Results: Respiratory rate (RR) and resistance (Rt) in prone were lower than those in supine, and tidal volume (Vt), minute ventilation (MV), dynamic compliance (Cdyn) and work of breathing (WOB) in prone were higher than those in supine. The value of pulmonary function in two position was as following:
