National Sudden Cardiac Arrest Awareness Month is observed every October and aims to raise awareness about the life-threatening emergency of sudden cardiac arrest, which can affect individuals of any age or background. The month emphasizes the importance of immediate action from bystanders, as survival rates significantly improve with quick intervention. Common customs include promoting CPR and AED training, sharing the "Call-Push-Shock" message, and encouraging community involvement through events such as heart screenings and CPR awareness days. Social media is also utilized to spread awareness by posting tips and resources. The initiative is supported by various organizations, including the American Heart Association and the Sudden Cardiac Arrest Foundation, which help educate the public on how to respond effectively in emergencies.
