Difficult Airway Algorithm and Rescue Cricothyrotomy (DAARC)

Welcome to the Difficult Airway Algorithm and Rescue Cricothyrotomy learning game. In this game, you’ll manage difficult airways using the Vortex Approach and implement the scalpel, spreader, and bougie open surgical cricothyrotomy technique. The objective of this game is to provide knowledge-based training for difficult airway management and the indications for and techniques of rescue cricothyrotomy. You will be assuming the role of an Airway Officer of the Day for your VA hospital. As the AOD, you will be the only airway provider in the facility at that time. You are expected to manage urgent and emergent airways in all areas of the hospital. All AODs at your facility are senior providers of Anesthesiology, Emergency Medicine, Critical Care, or Otolaryngology.
