What is the compression to ventilation ratio for an infant CPR in case of alone rescuer?

Appeared in: UPRVUNL - 2021

Explanation

According to Basic Life Support (BLS) guidelines, the standard compression-to-ventilation ratio for a single rescuer performing CPR on an infant is 30 compressions to 2 breaths.
This 30:2 ratio is standardized for single rescuers across infants, children, and adults to simplify training and improve recall during an emergency.
The primary goal is to provide high-quality chest compressions with minimal interruptions to maintain blood flow to vital organs.

Option A: 5:1 is not a standard compression-to-ventilation ratio in any current CPR guideline.
Option C: 20:10 is not a recognized CPR ratio. The number of breaths is typically low (1-2) to minimize interruption of chest compressions.
Option D: 10:3 is not a standard CPR ratio. It may be confused with the 3:1 ratio used for neonatal resuscitation.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Infant CPR compression-to-ventilation ratio for a single rescuer as background academic context rather than a clinical decision trigger.
Knowing the correct CPR ratio is a fundamental and critical skill for any nurse or healthcare provider to ensure effective basic life support and improve survival outcomes from pediatric cardiac arrest.
Most pediatric cardiac arrests are secondary to respiratory failure or shock. Therefore, while high-quality compressions are vital, providing effective ventilations is also a key component of resuscitation.
What if?: If a second healthcare provider arrives on the scene, the team should immediately switch the ratio to 15:2. This change increases the frequency of ventilations, which is beneficial for infants whose arrest is likely due to a respiratory cause.

How to Approach the Question

First, identify the key components of the question: the patient is an 'infant', the procedure is 'CPR', and there is an 'alone rescuer'.
Recall the standardized Basic Life Support (BLS) guidelines for CPR.
Differentiate the guidelines based on the number of rescuers. Single-rescuer protocols are often simplified for consistency.
Compare the single-rescuer infant ratio to other scenarios, such as two-rescuer infant CPR (15:2) or neonatal resuscitation (3:1), to confirm you are selecting the correct one.
Evaluate the given options and select the one that matches the established guideline for a single rescuer performing CPR on an infant.
