Nurse working in an ICU must be aware of the ratio of chest compression to ventilation in CPR procedure is:

Correct option is D

The standard CPR ratio for two-person rescuer technique, especially for children and sometimes in adults under special circumstances, is 15 compressions to 2 breaths. This ensures effective oxygen delivery and circulation. Though updated guidelines suggest 30:2 for adults in solo rescuer situations, ICU protocols may still teach 15:2 where two healthcare workers are present.
Explanation of options:
· (a) 12:1: This ratio is not part of any recognized CPR guidelines.
· (b) 12:2: No CPR protocol recommends a 12:2 compression to ventilation ratio.
· (c) 15:1: A ratio of 15 compressions to 1 breath does not provide sufficient ventilation.
· (d) 15:2: Correct ratio for two-person CPR in older or pediatric guidelines.
