Which action is recommended after each set of 30 compressions during CPR?

After each set of 30 compressions during CPR, it is recommended to look for and clear any obstruction if there is suspicion that the victim is choking. This is particularly crucial in situations where the victim is unresponsive and has been found pulseless, which may indicate an airway blockage that needs to be addressed immediately.

During CPR, the circulation provided by chest compressions can only be effective if the airway is clear. If an obstruction, such as food or another object, is blocking the airway, it can prevent oxygen from reaching the lungs and ultimately the brain. Therefore, after performing compressions, checking the airway to remove any obstructions is vital in increasing the chances of survival and ensuring that resuscitative efforts are effective.

The other actions, while important in different contexts of CPR and emergency response, do not directly follow the protocol after the compression cycles. For example, chest thrusts are used for conscious choking victims and not in conjunction with CPR. Checking for responsiveness does not align with the procedure after compression sets in a primary CPR scenario, especially when the person is already unresponsive. Additional back blows are also reserved for conscious individuals who are choking and not appropriate after chest compression sequences.
