Compression ratio for 1 rescuer Child/Infant CPR?

• A. 30:2
• B. 15:2
• C. 20:2
• D. 10:2

Answer: (A)

When a single rescuer performs CPR on a child or infant, the most effective pattern is to deliver 30 chest compressions and then give 2 rescue breaths. This sequence keeps blood flowing to vital organs while still allowing for oxygen to be delivered to the lungs between compressions. The emphasis is on maintaining a steady compression rate and minimizing pauses, because uninterrupted circulation is the key to sustaining life during CPR. The two breaths after the 30 compressions help re-oxygenate the lungs before the next round of compressions. If two rescuers are present, the pattern shifts to a smaller number of compressions before breaths to allow more time for ventilation, but with one rescuer, 30 compressions followed by 2 breaths is the standard. Aim for about 100–120 compressions per minute and compress to about one third of the chest depth, adjusting for the child’s or infant’s size.
