After each set of compressions during CPR for an unresponsive choking person, the correct action to take is to **attempt 2 ventilations**. Ventilations are crucial in CPR to ensure that oxygen is delivered to the person's lungs and body to keep them alive. By providing these ventilations, you are helping to maintain oxygen supply and circulation in the person's body, which is vital in a life-threatening situation like choking.
Here's a breakdown of the steps to follow after each set of compressions:
1. Perform a set of compressions (usually 30 compressions).
2. After the compressions, immediately deliver 2 ventilations by tilting the person's head back, lifting the chin, and creating a seal over their mouth for mouth-to-mouth breathing.
3. Watch for the person's chest to rise with each ventilation to ensure proper air intake.
Remember, the sequence of compressions and ventilations is crucial in CPR to maximize the chances of survival for the person in distress. By following these steps correctly, you are providing essential care until professional help arrives.
