Suffocation occurs when a person cannot breathe properly, often due to a blockage in the airway. This can happen if something gets stuck in the throat, like food or a small object. It can also occur in situations where there is not enough oxygen, such as being trapped in a closed space. Recognizing the signs of suffocation, like difficulty breathing or a blue tint to the skin, is crucial for quick action. In emergencies, performing the Heimlich maneuver can help dislodge an object from the throat. It's important to stay calm and call for help if someone is suffocating. Knowing basic first aid can save lives in these critical moments.
