What should you do if back blows are not effective in relieving choking?

When back blows are not effective in relieving choking, transitioning to chest thrusts is the appropriate course of action. Chest thrusts are designed to create internal pressure that can help expel the object blocking the airway. This technique is particularly useful because it can be applied to a person who is still conscious and able to respond, allowing for continued assistance in a critical situation.

Continuing back blows may not be beneficial if they are ineffective since they are not removing the obstruction. Calling emergency services is important if the situation escalates or if the person loses consciousness, but immediate action is essential before that point. Waiting for the person to cough on their own is risky, especially if the obstruction is severe enough to impede breathing, as it can lead to a critical situation where the person becomes unable to breathe at all. Therefore, switching to chest thrusts is the most proactive and effective response when back blows are unsuccessful.
