Vomit vs Regurgitation

The 2013 NLI Recert FAQ document posed the following question/answer regarding vomiting:

If a victim vomits during the 2 breaths, does the rescuer clear the airway and then check for breathing?

No. Research has shown that lay rescuers are unable to accurately tell the difference between vomiting and regurgitation. If a victim vomits during rescue breaths (or compressions), the rescuer will clear the airway; provide the ventilations, and then resume CPR. The rescuer will only reassess the patient if they are starting to show signs of consciousness.

It was brought to the attention of the Branch that the answer was unclear, especially surrounding the procedure where vomit/regurgitation is present during compressions versus rescue breaths.
