If they choked on something, I doubt they have enough space in their lungs to force it out. Clearing the obstructed airway should be the priority first perhaps by running your hands along the neck, then chest compressions to restart the heart and get blood moving oxygen around.
Just fyi, chest compressions cannot restart a heart, they can keep blood flowing until an AKG can get it into a normal heartbeat. If the heart is completely stopped, neither compressions or an AKG can do anything.
