A medical crisis occurs when a person's health suddenly deteriorates, requiring immediate attention. This can happen due to various reasons, such as a heart attack, stroke, or severe allergic reaction. In these situations, quick action is crucial, as delays can lead to serious complications or even death. During a medical crisis, it's important to recognize the signs and symptoms early. For instance, if someone experiences chest pain or difficulty breathing, calling emergency services right away can save their life. Understanding how to respond in these moments can make a significant difference in the outcome for the affected individual.
