When attempting to expel a foreign body from a very obese or pregnant person, the proper hand placement is on the abdomen between the breastbone and belly button. This technique is known as the Heimlich maneuver and involves the following steps:
1. Stand behind the person and slightly to one side.
2. Wrap your arms around the person's waist.
3. Make a fist with one hand and place it slightly above the navel but below the ribcage.
4. Grasp your fist with your other hand and press into the abdomen with a quick upward thrust.
This action helps to create enough pressure to expel the foreign object from the airway. It is important to perform this maneuver carefully and with the right technique to avoid causing harm to the person in distress. Remember to seek professional medical help if the foreign body is not expelled or if the person shows signs of severe distress.
