Inflating pressures for effective resuscitation of preterm infants

The magnitude of inflating pressure necessary for effective resuscitation was examined in 70 preterm infants. The median pressure to cause adequate chest wall expansion was 22.8 cmH2O; no infant required a peak inflating pressure greater than 30 cmH2O. No further increase in inflation pressure was used during resuscitation and the median 5- and 10-min Apgar scores were 8 and 9, respectively.
