Heart health is often associated with adults, but children’s heart health is just as important. While serious cardiac events in children are rare, heart conditions can exist from birth or develop over time. Awareness, healthy habits, and emergency preparedness play a vital role in keeping children safe.

Opioid overdoses are a growing public health concern and can quickly become life-threatening. While many people associate overdoses primarily with breathing problems, severe opioid toxicity can ultimately lead to cardiac arrest if not treated promptly.

Chest compressions are the cornerstone of cardiopulmonary resuscitation (CPR). While they may appear simple, compressions are based on well-established physiological principles that help keep blood—and oxygen—moving to vital organs during cardiac arrest.

During cardiac arrest, the heart suddenly stops pumping blood, cutting off oxygen supply to the brain. This lack of oxygen—known as hypoxia—causes rapid and potentially irreversible brain damage within minutes. Understanding how oxygen deprivation affects the brain highlights why immediate response and proper training such as CPR certification are critical for survival and neurological recovery.

Experiencing or responding to a traumatic event—such as cardiac arrest, severe injury, or sudden medical emergency—can have lasting psychological effects. While much attention is given to physical recovery, mental health after trauma is equally important for both survivors and rescuers.

Technology is transforming how emergencies are detected, reported, and managed. From smartphone apps that alert nearby responders to wearable devices that monitor vital signs in real time, digital tools are becoming powerful allies in saving lives.

The American Heart Association (AHA) regularly updates its resuscitation guidelines to reflect the latest scientific evidence. These updates play a crucial role in improving survival rates and neurological outcomes for cardiac arrest victims.

When cardiac arrest occurs outside a hospital, survival and recovery depend heavily on the actions taken in the first few minutes. Among the most critical interventions is bystander CPR, which not only increases survival rates but also plays a major role in preserving neurological function.

Cardiac arrest is often sudden and unexpected, but in many cases, the risk builds silently over time. Daily lifestyle choices—such as diet, physical activity, stress management, and smoking—play a major role in determining heart health and overall survival risk.

Cardiopulmonary resuscitation (CPR) is often described as a life-saving technique—but what actually happens inside the body when CPR is performed? Understanding the physiology of CPR explains why proper technique, timing, and CPR certification are critical for survival during cardiac arrest.
