According to the Centers for Disease Control and Prevention, traumatic injury is one of the leading causes of death for people under 50 years of age in the United States. A large portion of those deaths are from severe bleeding – the most treatable cause of death due to trauma. The HSI Stop Life-Threatening Bleeding program is a completely revised and updated training program, integrating the latest and new Stop Life-Threatening Bleeding procedure. This program uses a step-by-step procedure and skill guide to provide guidance for assessing, prioritizing, and stopping life-threatening bleeding based on scientific evidence, national guidelines, and the consensus of experts. HSI's Stop Life-Threatening Bleeding program is an excellent supplement to our CPR and First Aid programs. This Program has been approved by the HSI Medical Advisory Board and reviewed by the HSI Advisory Council. It reflects the latest resuscitation science and treatment recommendations published by the International Liaison Committee on Resuscitation (ILCOR) and conforms with the 2020 American Heart Association (AHA) Guidelines Update for CPR and ECC and the annual Guidelines Update.
