When it comes to choking, every second counts. 

Whether it's a loved one or a complete stranger, there is a lot to be said for choking awareness. Being at the right place at the right time – and knowing how to jump into action – can mean the difference between life and death. 

In addition to knowing how to prevent choking, it is vital to know what to do when someone appears to be choking. Time is of the essence when it comes to a lack of oxygen. 

When a person is choking, his or her airway has become blocked and won't allow air to get into the lungs. According to the National Institute for Neurological Disorders and Stroke, after five minutes without oxygen, the brain cells start to die. If oxygen deprivation continues, permanent brain damage can occur. That's why it is critical to prevent choking whenever possible and act quickly if an accident does take place.
