What is the next step for a choking victim after calling for emergency assistance?

In a situation involving a choking victim, after calling for emergency assistance, the appropriate next step is indeed to begin CPR with compressions using the C-A-B sequence, particularly if the victim becomes unresponsive and is unable to breathe or cough effectively.

The C-A-B sequence stands for Compressions, Airway, and Breathing. This procedure emphasizes the importance of chest compressions first when a victim is unresponsive, promoting blood circulation to vital organs. Starting with compressions is crucial, especially if the victim has lost consciousness, as this helps maintain some level of blood flow until professional help arrives.

It's also important to note that the other responses would not be the immediate next step after calling for help. Performing abdominal thrusts is appropriate if the choking victim is still conscious and able to provide some indication of distress, but it would not proceed after the victim has become unresponsive. Starting CPR with breaths would imply that breathing can be established, which is not the case here where the victim is unresponsive. Checking the pulse may take time and is less critical than ensuring oxygenated blood is circulating through compressions, especially in an emergency setting.
