At a restaurant, a customer chokes on a piece of food. You put your arms around the person's waist and use your fists to push up on the person's abdomen, an action called the heimichi manuver
How would this action change the volume of the chest and lungs? Why does it cause the person to expel the food item from the airway?

2. A piece of food would be dislodged with a sufficiently (high) pressure.
1. The volume of the chest and lungs will (increase), which will cause the pressure to (decrease).
2. A piece of food would be dislodged with a sufficiently (high) pressure.
1. The volume of the chest and lungs will (increase), which will cause the pressure to (decrease).
Explanation: When performing the Heimlich maneuver, the action of pushing up on the person's abdomen increases the volume of the chest and lungs. This increase in volume leads to a decrease in pressure within the lungs.
2. A piece of food would be dislodged with a sufficiently (high) pressure.
Explanation: Applying a sufficiently high pressure to the abdomen during the Heimlich maneuver creates a force that helps to expel the trapped food item from the airway. The force generated from this pressure can dislodge the lodged food and force it out of the airway.
