Modified CPR for unconscious patient with foreign body obstruction, what is the sequence?

• A. Visualize, compressions, ventilations
• B. Compressions, Visualize for object, Ventilations
• C. Ventilations, Compressions, Visualize
• D. Compressions, Ventilations, Visualize

Answer: (B)

When someone is unconscious and choking, the priority is to keep blood flowing first, then clear the airway so ventilation canoccur. Start with chest compressions to maintain perfusion. After the first round of compressions, open the airway and look for the obstruction. If you can see it, remove it carefully. Then deliver ventilations. If air does not go in, recheck the airway and continue cycles of compressions and ventilations, repeating the search/removal if possible on each cycle.

This sequence avoids delaying chest compressions, which are essential to preserve brain and heart oxygenation, and focuses on clearing the blockage to allow effective breaths. Ventilating before addressing the obstruction or delaying compressions would be less effective in this scenario.
