Emergency Response
9-1-1 Emergency Ambulance Service
When you dial 9-1-1 in our service areas, Mercy crews are dispatched through the county 9-1-1 system to respond to medical emergencies. We provide two levels of emergency care in San Diego, Mariposa, and Tuolumne counties.
Paramedic-level care
Advanced Life Support (ALS)
Advanced Life Support is paramedic-level emergency care delivered on scene and en route to the hospital. Paramedics can perform advanced interventions — such as administering medications, advanced airway management, and cardiac monitoring — that go beyond basic first aid.
ALS units are dispatched through the county 9-1-1 system. There is nothing to request here: if you have a medical emergency, call 911 and the dispatcher will send the appropriate response.
You cannot request an ambulance through this website. Always call 911 for an emergency.
EMT-level care
Basic Life Support (BLS)
Basic Life Support is EMT-level care and medically supervised transport for patients whose condition does not require paramedic-level interventions. BLS crews are trained in essential emergency care, monitoring, and safe patient handling throughout the trip.
Like our ALS units, BLS ambulances respond through the county 9-1-1 system in San Diego, Mariposa, and Tuolumne counties.
Higher Level of Care
Critical Care Transport (CCT)Mariposa & Tuolumne Counties
Critical Care Transport is for facility-to-facility transfers where a patient needs a higher level of monitoring and care en route than a standard ambulance provides. It bridges the gap between hospital-level care and traditional ambulance transport.
Mercy provides Critical Care Transport in Mariposa and Tuolumne counties. CCT is arranged by phone — call the Mariposa County line to coordinate a transfer.
