Question

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

Answer 1

During chest compressions in CPR, the correct compression to ventilation ratio is 30 compressions to 2 ventilations, not 15:3 or the sequence of 3 compressions to 1 ventilation. The emphasis is on high-quality chest compressions instead of coordinating breathing with compressions using phrases.

Step-by-step explanation:

During chest compressions in cardiopulmonary resuscitation (CPR), it's important to follow the updated guidelines to ensure effective support for the patient. The student's question contains several points which need clarification. The current standard for the compression to ventilation ratio is 30 compressions to 2 ventilations for adults, and this applies to children and infants, with exception for newborns. One cycle does not fit a set time frame but should be based on proper technique and speed, which is about 100 to 120 compressions per minute. The guideline of saying "Breathe-two-three" is not a current recommendation; instead, the person performing CPR should focus on delivering high-quality compressions with minimal interruptions. Lastly, while some babies who require chest compressions may need a volume expander, this is based on specific circumstances and not a general rule for all cases.

Answer 2

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.
