M.A.R.C.H. - The Acronym That Saves Lives

The M.A.R.C.H. algorithm is the heart of TCCC and the mental roadmap for every responder in a trauma situation. It is a simple acronym that prioritizes medical interventions based on the leading causes of preventable death. Following this sequence ensures that the most immediate life threats are addressed first. This entire educational collection is structured around this life-saving mnemonic.

M stands for Massive Hemorrhage. Uncontrolled bleeding is the number one cause of preventable death in trauma. Therefore, stopping massive bleeding with tourniquets, wound packing, and pressure dressings is always the first and most important medical priority.

A stands for Airway. Once bleeding is controlled, the responder must ensure the casualty has a patent airway. A person who cannot get air in cannot survive, so interventions like the jaw-thrust maneuver or inserting a nasopharyngeal airway (NPA) are performed next.

R stands for Respiration. After ensuring the airway is open, the focus shifts to the casualty's breathing. This involves identifying and treating life-threatening chest injuries, such as a sucking chest wound or a developing tension pneumothorax, primarily through the use of chest seals.

C stands for Circulation. This step involves a broader check for bleeding and, more importantly, the prevention and treatment of shock, which is often a consequence of significant blood loss.

H stands for Hypothermia and Head Injury. This final step addresses two critical but often overlooked issues. Preventing hypothermia (getting cold) is vital, as it can prevent blood from clotting and is a key component of the "trauma triad of death." This step also includes assessing for head injuries and documenting all findings and interventions.
