A medical emergency is a situation that requires immediate attention to prevent serious harm or death. Common examples include heart attacks, strokes, severe injuries, or allergic reactions. Recognizing the signs of these emergencies, such as chest pain, difficulty breathing, or sudden weakness, is crucial for timely intervention. In many cases, calling emergency services is the first step in addressing a medical emergency. Trained professionals can provide critical care and transport patients to a hospital if necessary. Quick action can significantly improve outcomes, making it essential for individuals to be aware of how to respond in such situations.
