The initial assessment of a potentially critical patient begins with a rapid overview consisting of two assessments and related measures to consider:



  • Potential measures include putting on gloves, protective clothing, visors, calling for additional help; in the prehospital environment, measures may include waiting for the police or fire department to secure the scene and relocating to a safer working environment



  • Cardiac arrest should be recognized immediately and followed by advanced cardiopulmonary resuscitation
  • For other potentially critical patients, the next step is to carry out the ABCDE algorithm
