What is the compression to ventilation ratio for one rescuer?

The compression to ventilation ratio for one rescuer performing cardiopulmonary resuscitation (CPR) on a child or infant is 30:2. This means that for every 30 compressions performed, the rescuer should provide 2 rescue breaths. This ratio is based on the guidelines established to optimize the chances of survival in pediatric patients experiencing a cardiac arrest.

The 30:2 ratio allows for a higher number of chest compressions while still incorporating effective ventilations, thus improving the delivery of oxygen to the child's vital organs. In a single rescuer scenario, it's essential to maintain a balance between compressions and breaths to ensure adequate perfusion and oxygenation. Following this ratio is critical in sustaining blood flow during cardiac arrest until advanced medical help can be provided.

Understanding this ratio is vital for effective CPR, as proper techniques and adherence to recommended guidelines significantly impact outcomes for children in emergency situations.
