What is the first step in addressing a suspected airway obstruction?

Performing back blows and abdominal thrusts is the appropriate first step in addressing a suspected airway obstruction, particularly if the person is conscious and unable to speak or breathe effectively. This approach is part of the immediate action you can take to try and dislodge the obstruction in the airway. Back blows aim to create enough force to expel the obstruction, while abdominal thrusts (also known as the Heimlich maneuver) apply pressure beneath the diaphragm to force the object out.

In an emergency scenario where airway obstruction is suspected, time is critical. Immediate intervention can prevent severe complications, such as loss of consciousness or death from lack of oxygen. The other options may not address the urgency of the situation effectively. For instance, requesting additional help could delay necessary action, which can be fatal in cases of severe airway blockage. Administering oxygen does not resolve the blockage itself, as oxygen cannot be delivered effectively if the airway is obstructed. Trying to reason with the patient is not practical in a situation where they may be struggling to breathe or communicate.
