Studies show a distending pressure is important for maintaining FRC (48), increasing lung compliance and improving oxygenation, and that 8 cm H 2 O is more effective than a lower pressure (49). Studies have used pressures up to 10 cm H 2 O (50) and Gregory et al(51) used a nCPAP pressure up to 12 mm Hg.…”

There are no data describing how very preterm infants breathe spontaneously immediately after birth. We studied a convenience sample of spontaneously breathing infants Յ32 wk' gestation treated with facemask continuous positive airway pressure at birth. Airway pressure and flow were measured and each breath analyzed. Twelve infants had 792 breaths suitable for analysis. Results are given as mean (SD). Gestational age and birth weight were 29 (1.9) wk and 1220 (412) g. Recordings were started 159 (77) s after birth. The inspiratory pattern and duration was similar in all breaths at 0.36 (0.11) s. There were five expiratory patterns; most infants had more than one. In 79% of breaths expiratory duration (1.6 (1.1) s) was slowed or held by interruption or braking of expiratory flow. It was braked in 47% to a complete expiratory hold, in 22% by grunting or crying, and in 10% by slow or interrupted expiration. In 21% of the breaths, expiration was not interrupted and lasted 0.53 (0.13) s. Half of these breaths represented a panting pattern (rate Ͼ60 /min). Immediately after birth, most very preterm infants, treated with continuous positive airway pressure, frequently prolong their expiration by braking the expiratory flow.

“…In the infants on CPAP there was an increased EEL at 2 h which corresponded with improved homogeneity and increased regional ventilation of the posterior lung. This is not surprising as it is widely acknowledged that CPAP increases EEL (32)(33)(34). It has been speculated that the dynamic volumepreserving mechanisms resulting from expiratory flow braking are not required during CPAP, as the constant pressure passively elevates functional residual capacity (30,32).…”

“…As metilxantinas e a cafeína são os fármacos mais comumente utilizados. A CPAP nasal e mais recentemente a VNPPI também encontram-se bem estabelecidas no tratamento da ADP 65,66 . Infelizmente, nenhum estudo randomizado foi realizado para comparar o tratamento farmacológico com o não-farmacológico da ADP.…”
