During neonatal resuscitation, the chest compression to ventilation ratio is ___________ 
Select and explain. 
A. 3:01, B. 5:01, C. 10:01, D. 15:01
A: 3:01
Answer: A: 3:01 
Explanation: * Chest compressions consists of rhythmic compressions of sternum that compress the hea against the spine , increase the intra thoracic pressure and circulate the blood to vital organs of the body . *It is impoant to ventilate in between chest compressions. A positive breath should follow every third chest compression(chest compression to ventilation ratio is 3:1). In one minute, 90 chest compressions and 30 breaths are administered(120 events). To obtain this, the chest should be compressed 3 times in 1.5 seconds leaving out approx. 0.5 second for ventilation. Reference: page 131 Ghai Essential Pediatrics 9 th edition
