Factors modulating effective chest compressions in the neonatal period.

The need for chest compressions in the newborn is a rare occurrence. The methods employed for delivery of chest compressions have been poorly researched. Techniques that have been studied include compression:ventilation ratios, thumb versus finger method of delivering compressions, depth of compression, site on chest of compression, synchrony or asynchrony of breaths with compressions, and modalities to improve the compression technique and consistency. Although still in its early days, an evidence-based guideline for chest compressions is beginning to take shape.
