What would you do if the chest of a victim did not expand while given Breathing?

If the chest of the victim does not expand while giving rescue breaths, it could indicate a blockage or obstruction in the airway. Here's what you should do in such a situation:

1. Check for Obstruction: Make sure that there's no foreign object or blockage in the victim's mouth or throat that might obstruct airflow. Open the mouth, ensure the tongue isn't blocking the airway, and perform a quick visual check. Remove any visible obstructions if present.

2. Turn the Victim: Carefully turn the victim to one side, ensuring they're in the "recovery" position. This can help any obstructions or fluids move from the airway and mouth.

3. Perform Back Blows: Give up to 5 back blows to help dislodge any blockage. For back blows, position the victim prone and administer forceful hand strikes between the shoulder blades.

4. Chest Thrusts: If back blows don't help, perform chest thrusts (also called abdominal thrusts or the Heimlich maneuver). Position yourself behind the victim and give forceful upward thrusts to the abdomen until the object is expelled.

5. Continue Attempts: Alternate between back blows and chest thrusts. After each set, try a rescue breath. If necessary, continue administering chest compressions alternating with breaths until the blockage is cleared or emergency help arrives.

6. Seek Emergency Help: If the blockage doesn't clear despite your efforts or the victim remains unconscious, call for emergency medical assistance immediately.

Remember to remain calm and follow the correct techniques to ensure you assist the victim effectively.
