**Question:** In Neonatal Resuscitation, chest compression to ventilation ratio is:

A. 30:2
B. 15:2
C. 20:1
D. 15:2

**Correct Answer:** A. 30:2

**Core Concept:**
The chest compression to ventilation ratio refers to the recommended sequence of chest compressions and ventilations during neonatal resuscitation. This ratio ensures effective circulation and gas exchange in the newborn.

**Why the Correct Answer is Right:**
The correct answer is A. 30:2. This ratio is used in neonatal resuscitation as it provides adequate circulation, allowing the heart to fill with blood, and sufficient gas exchange in the lungs. In this scenario, 30 chest compressions are performed at a rate of around 60 compressions per minute, followed by 2 ventilations (inhalations). This ratio allows for adequate oxygenation and circulation during resuscitation efforts.

**Why Each Wrong Option is Incorrect:**

B. 15:2 is too fast, leading to inadequate circulation and gas exchange.
C. 20:1 is too slow, potentially causing hypoxia and myocardial depression.
D. 15:2 is faster than the correct ratio, resulting in suboptimal circulation and gas exchange.

**Clinical Pearl:**
The understanding of chest compression to ventilation ratio is crucial for neonatal resuscitation, as this ensures the best chance of successful infant stabilization and recovery. The correct ratio (30:2) is based on maintaining an adequate balance between circulation and gas exchange during resuscitation. Remember to use this ratio when performing neonatal resuscitation to improve the neonate's survival rate and overall health outcome.
