Suction (mechanical) Pressure relief valve Straight blades (#0 and #1) Warmer M.E.J. ANESTH 20 (1), 2009 NEONATAL RESUSCITATION and there is right to left shunting of blood across the foramen ovale and ductus arteriosus umbilical cord significantly increases systemic vascular resistance and contributes to a functional closure of the foramen ovale within the first few minutes of birth. A left to right reversal of the shunt across the ductus arteriosus results.. Because it takes days to weeks for the ductus arteriosus to anatomically close, there may be a right to left reversal of the shunt anytime pulmonary vascular resistance rises above systemic. Several states can predispose the infant to this reversal during this “transitional phase” . Conditions such as meconium aspirations can result in a more persistent Table 2 The �ve criteria of the APGAR score Table 3 Biophysical Pro�le Tests and Criteria Biophysical Profile Test M.E.J.

This can be accomplished by simply placing the neonate under a radiant warmer. The infant should be uncovered to allow for full visualization and adequate heat transference. Thermoregulation is particularly important in very low M.E.J.
