Question

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 Heimlich maneuver. $(11.3)$ a. How would this action change the volume of the chest and lungs? b. Why does it cause the person to expel the food item from the airway?

Key Concepts

Intrathoracic Pressure Change

When you perform the Heimlich maneuver, the upward thrust on the abdomen forces the diaphragm upward, thereby reducing the volume of the chest cavity. This decrease in volume leads to a rapid increase in intrathoracic pressure, which is key to the technique's effectiveness.

Pressure-Volume Relationship (Boyle’s Law)

Boyle’s Law states that under constant temperature, decreasing the volume of a gas increases its pressure. In the context of the Heimlich maneuver, the increased pressure within the lungs forces air out quickly through the airway, which helps to expel the obstructing piece of food.
