The Critical System Monitor (CSM) is a safety feature for professional bouts of Strata Free-form Combat.

Strata is renowned for its incredible record of safety. Before each bout, the combatants are injected with a Critical System Monitor (CSM) capsule. The CSM continuously feeds vital sign information to the officials, medical staff and the combatant’s team. In over 40 years of professional strata there have only been 2 fatalities. However, underground bouts are a different story (3.4.8).
