During chest compressions, which of the following is correct? the compression to ventilation ratio is 15 compressions : 3 ventilations one cycle of 3 compressions and 1 ventilation should take approximately 2 seconds to coordinate compressions and ventilations, the compressor calls out "breathe-two-three, breathe-two-three…" most babies who require chest compressions will also require volume expander

When performing chest compression for babies, the preferred technique should be one cycle of 3 compression and 1 ventilation should take approximately 2 seconds or 1/3 the anterior-posterior diameter of the chest.

While doing the 2-finger technique for chest compression, the second hand must support the back of the baby and the compression chanting must be One-and-Two-and-Three-and-Breath.

Moreover, the compression to ventilation ratio in one minute for newborn is 90 compressions: 30 ventilations.
