I called 911 last year when my wife was unresponsive in Maryland. At least 10 vehicles arrived in under 10 minutes. EMTs worked to revive her for 30 minutes doing what they described as the same care she would have received at the emergency room.
She was transported to the hospital because she had a slight heart beat. Had she been declared dead at home, police and other staff would have helped process the death report and application for death certificate. I did not receive a bill or provide insurance information.
