What should be done if a patient's airway is obstructed during an emergency?

When a patient's airway is obstructed during an emergency, performing abdominal thrusts is the recommended intervention, particularly in cases of choking. This technique is designed to create pressure in the abdomen, which can help expel the object blocking the airway. It is crucial in restoring normal breathing and preventing potential asphyxia.

In situations of airway obstruction, immediate action is required to prevent the patient from losing consciousness or suffering serious harm. Abdominal thrusts effectively use the body's own force to dislodge the object, making it a key maneuver taught in first aid and emergency response protocols.

The other options are not appropriate responses to a choking emergency. Calling for backup might be necessary if the situation escalates or additional help is needed, but it does not address the immediate threat of airway obstruction. Administering IV fluids is not relevant in the context of a blocked airway and would not assist in clearing the obstruction. Similarly, checking for pulse, while important in some scenarios, does not directly impact the treatment of a choking patient; the focus should be on clearing the airway first.
