Which two conditions could lead you to suspect someone is in cardiac arrest?

The presence of chest pain along with not breathing can be critical indicators that someone may be experiencing cardiac arrest. Chest pain often signals a heart-related issue, such as a heart attack, which can lead to the heart stopping its function. When a person is not breathing, it means that their body is not receiving the oxygen necessary to sustain life, further confirming that their cardiac function may have ceased. In cases of cardiac arrest, the heart stops pumping blood effectively, leading to a lack of oxygen in the body and typically resulting in the individual being unresponsive as well. Therefore, recognizing these two signs together provides significant evidence of a possible cardiac arrest situation, warranting immediate emergency response and intervention, such as CPR and calling for emergency medical services.
