Final answer:
In 2-rescuer CPR for an unwitnessed child cardiac arrest, one rescuer starts chest compressions while the other activates the emergency response system and retrieves an AED. The compression-to-ventilation ratio is 15:2. CPR must continue until the child recovers or medical professionals take over.
Step-by-step explanation:
Emergency Response and CPR Procedures for Unwitnessed Child Cardiac Arrest
For a child with unwitnessed cardiac arrest, the guidelines for 2-rescuer CPR dictate that the first rescuer should begin chest compressions immediately, while the second rescuer activates the emergency response system and, if available, retrieves an automated external defibrillator (AED). It is critical to minimize delays in starting CPR which is vital for increasing the chances of survival and reducing potential brain damage. The recommended compression-to-ventilation ratio for CPR in children by two rescuers is 15 compressions to 2 ventilations. This ratio ensures that the child receives both adequate circulation through chest compressions and essential oxygenation through ventilations.
When performing CPR, the rescuers should compress the chest at least 5 cm deep at a rate of about 100 compressions per minute, which is similar to the beat of the song "Staying Alive." High-quality chest compressions are emphasized over artificial respiration; however, both are necessary to help maintain blood circulation and oxygenation. CPR should continue until the patient regains a heartbeat or is taken over by medical professionals.
It is important to note that CPR can cause injuries if not performed correctly, and therefore proper training and certification are highly recommended. The knowledge and skill to provide CPR are crucial and can be life-saving in emergency situations
