Combating Cardiac Arrest

What kills more people than AIDS, breast cancer, and lung cancer combined? Cardiac arrest.

Cardiac arrest is the heart’s inability to contract properly which causes the blood to stop circulating. When this occurs, the brain doesn’t receive oxygen which can lead to death in a matter of minutes. Cardiac arrest kills an average of 1,000 people every day.

In this episode of Health Matters, Dr. David Granet and his guest, Dr. Ulrika Birgersdotter-Green, introduce the newest device called an Implantable Cardioverter Defibrillator that could help save lives.

Watch “Implantable Cardioverter Defibrillators and Sudden Cardiac Death” to discover how it works in conjunction with the heart’s electrical system and learn tips for lowering your risk of cardiac arrest.

Fighting Food Allergies in Children

Every three minutes some one goes to the emergency room because of an allergy-related event.

When you have an allergic reaction to something you eat, your body recognizes a protein in the food and reacts against it. There are many different responses that can happen-rashes, hives, diarrhea-but, the most dangerous occurrence is when there is potential for anaphylaxis, which can cause death.

In this episode of Health Matters, Dr. David Granet talks with UC San Diego’s Dr. Stephanie Leonard who is the director of the Food Allergy Center at Rady Children’s Hospital here in San Diego.

More than 3 million people under the age of 18 have been diagnosed with food allergies, but Dr. Leonard says that number is on the rise. In a ten year period, she says, there has been an 18% increase in the diagnosis of food allergies in children.

Watch “Children’s Food Allergies- Health Matters” to hear the various theories behind why that number is increasing.
