As a Retired Navy Hospital Corpsman who also has 37+ years of prehospital experience as a licensed EMT-PARAMEDIC and an Instructor, at the time of this episode, any bystander is covered by the Good Samaritan law, as long as they do not attempt an "invasive procedure". When the Corpsman performed an emergency tracheotomy, she crossed the line of Good Samaritan. This procedure is taught to Hospital Corpsman to be used in the field, and to Advanced EMT''s, such as NREMT-Intermediate or Paramedics. Upon discharge from the Navy, if you do not have these civilian certifications, you are held responsible for your actions. Rendering basic first aid, performing CPR, rescue breathing, etc. Is all that is covered under the Good Samaritan law. This was a good example of getting the certification before getting out of the service is important.
