What is the compression to ventilation ratio in an infant during neonatal resuscitation?

Appeared in: NORCET 2 - 2021 (shift-1)

Explanation

The standard compression-to-ventilation ratio for neonatal resuscitation at birth is 3:1.
This ratio is designed to deliver 90 compressions and 30 breaths per minute, totaling 120 events.
The focus is on ventilation because cardiac arrest in newborns is typically secondary to respiratory failure.
Compressions are initiated only if the heart rate is below 60 bpm despite 30 seconds of effective positive-pressure ventilation (PPV).

Option B: This ratio is incorrect for neonatal resuscitation at birth.
Option C: This ratio provides too many breaths and insufficient compressions, which would fail to maintain circulation.
Option D: This ratio provides far too many breaths relative to compressions and is not a standard guideline.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Neonatal Resuscitation Program (NRP) Guidelines as background academic context rather than a clinical decision trigger.
The 3:1 ratio is a critical, life-saving intervention. The most important step in neonatal resuscitation is establishing effective ventilation. Compressions are secondary and only initiated if ventilation fails to restore heart rate.
Nurses must be able to differentiate between neonatal resuscitation (NRP) at birth and pediatric CPR (PALS/BLS) for an infant on the ward. Using the wrong ratio can be detrimental.
What if? If a newborn's heart rate is 70 bpm but they have poor respiratory effort, the correct action is to provide positive-pressure ventilation (PPV), not to start chest compressions. Compressions are only for a heart rate below 60 bpm despite effective PPV.

How to Approach the Question

First, identify the key terms in the question: 'compression to ventilation ratio', 'infant', and 'neonatal resuscitation'.
Recognize that 'neonatal resuscitation' refers to the specific protocols (NRP) used immediately after birth, which differ from standard pediatric CPR (PALS/BLS).
Recall the specific ratio recommended by NRP guidelines for newborns.
Evaluate the options. The 3:1 ratio is unique to neonatal resuscitation.
Differentiate this from the 15:2 ratio, which is used for two-rescuer pediatric CPR, and the 30:2 ratio for single-rescuer CPR.
