What should you do if a choking person is too large to give abdominal thrusts, or is obviously pregnant?

When a choking person is too large for abdominal thrusts or is obviously pregnant, giving chest thrusts is the recommended course of action. This technique is effective for individuals who cannot be properly positioned for abdominal thrusts due to their size or condition.

Chest thrusts help to create pressure in the chest cavity that can expel the obstructing object from the airway. This method is similar to how CPR is performed and utilizes the strength of the chest to generate the necessary force. It is particularly important for those who cannot safely receive abdominal thrusts, as improperly applied abdominal thrusts could potentially cause harm or exacerbate the situation.

In contrast, giving back blows could still be beneficial for a person who is not too large or pregnant, but it is generally not the primary technique recommended in these specific circumstances. While waiting for emergency medical personnel sounds prudent, it is essential to take immediate action when someone is choking. Leaving the person alone would not be a compassionate or responsible choice, as they could become unconscious without intervention. Thus, utilizing chest thrusts is the appropriate response in this scenario.
