How should a rescuer position a choking pregnant woman for back blows?

When a rescuer is assisting a choking pregnant woman, it is important to position her correctly for back blows to create the maximum chance of dislodging the obstruction safely and effectively. Bending the woman forward allows gravity to assist in moving the obstructing object out of the airway. This position lets the force of the back blows exerted by the rescuer have a better chance of impacting the diaphragm and respiratory passageways while minimizing the risk of injury to the fetus.

Additionally, this posture can help to alleviate pressure on the pregnant woman's abdomen, reducing any risks associated with applying force while she is in a lying position. Therefore, positioning her by bending forward is the most effective technique in this scenario, ensuring that both the mother and her unborn child are afforded the safest means of receiving emergency assistance.
