How should a lifeguard respond to a conscious choking victim?

When responding to a conscious choking victim, performing the Heimlich maneuver is the correct course of action because it effectively dislodges an object from the airway. This technique utilizes upward abdominal thrusts to create pressure that can expel the obstruction without additional delay. By encouraging the victim to cough, while potentially beneficial in less severe cases of choking, may not be sufficient to resolve the blockage in instances where the airway is partially obstructed or completely blocked.

The Heimlich maneuver is specifically designed for these urgent situations, where the victim cannot breathe, speak, or cough effectively. The immediate application of abdominal thrusts targets the cause directly and can provide quick relief, allowing the victim to breathe normally again.

Additionally, offering water is inappropriate in this scenario, as it could cause further obstruction if the individual is unable to swallow properly. Asking the victim to sit down and rest does not address the critical issue of airway blockage and may lead to a worsening condition. Therefore, performing the Heimlich maneuver while encouraging coughing is the most effective and appropriate response.
