RE History of Pre Hospital Care
Roots of Para Medicine
Para-medicines roots grow from military actions
Paintings of Ancient Roman battle fields suggest some
warriors cared for wounded soldiers
Modern warfare produced the military battlefield
ambulance corps medic.
These physician extenders provided advanced first aide to
wounded soldiers until transported to a field hospital
1966 The White paper “Accidental Death and Disability:
The Neglected Disease of Modern Society”
› U.S. researchers concluded that servicemen wounded in battle had
better rates of survival than motorists injured on California freeways
› This inspired the first experiments with use of civilian Paramedics in
the U.S.
1973 Congressional Emergency Medical Services Systems
Act allowing for access to federal funding
1975 AMA accepts and approves the EMT-Paramedic role
as an emergency health profession
› The DOT is responsible for establishing the training requirements of
Paramedics and EMT’s
Two main types of EMS services were created
› Hospital based programs with some medical training
provided by the sponsoring hospital
› Funeral homes with volunteers who had little or no
training in first aide or medical care, providing transport
with use of the hearse

RN History of Ambulances
Hammocks were readily available and used for centuries.
In Roman and Greek times chariots served as ambulances
In 1100 A.D. the Normans arrived in England with the
innovative horse litter
Modern Day Hammock Ambulance
Moving injured soldiers from the battlefield: Civil War
City Ambulance circa 1890
The first motorized ambulance appeared in 1899.
The ambulance had a top speed of sixteen miles an hour.
Ambulances had two horsepower electrical engines with
capability of traveling as far as twenty to thirty miles.
World War I Troop Ambulance
1948 Cadillac A. J. Miller hearse modified into an ambulance
Rapid advancements took place in the late 1950s to
1960s allowing for basic patient care by an attendant
while being transported to a hospital
Physicians came to realize that treatment at the scene
could make a difference between life and death.

CES History of Air Ambulances
Air Medical Transport in the begining
The first known Air Medical Transport vehicle was invented
by Chief of Dutch Medical Services, deMooy
› deMooy realized surface transport was a major cause of death to
injured combatants. He devised a stretcher suspended from a hot air
balloon drawn by horses
The hot air balloon air medical transport was used during
the siege of Paris in 1870
› 160 wounded French soldiers were successfully transported
Shortly after the Wright brothers successfully flew their
first airplane, two US Army medical officers designed an
airplane to transport patients.
The worlds first modern air ambulance was flown at Fort
Barrancas, Florida, in 1910. › Unfortunately, on its first test flight, it flew only 500 yards at an
altitude of 100 feet before crashing.
The first fixed wing air ambulance used by military was
during World War I in 1915
› A wounded French soldier was evacuated from Serbia by airplane.
1918 the U.S. Army modified a Curtiss JN-4D to carry
patients on a liter strapped to the rear cockpit.
› The rear cockpit was modified to accommodate a standard Army
stretcher carrying an injured person in a semi-reclined seat
Curtiss JN – 4D “Jenny” circa 1918
The first civilian air medical transport was completed in 1928 when a DeHaviland Fox Moth aircraft in the service of Australia's Royal Flying Doctor Service took off on its first mission.
DeHaviland Fox Moth circa 1940
War soon demonstrated the necessity of air evacuation.
The Burma Hump airlift operation saw what was probably
the first use of helicopters for combat rescue
› Airplane downed 100 miles behind enemy lines, remote and
inaccessible area
The first dedicated use of helicopters for air medical
transport was by the U.S. Government during the Korean
war 1950 - 1953
Bell Helicopter in Korea circa 1950
Patients carried outside aircraft, no medical care
in transit
H1- “Huey” Vietnam circa 1970
Transition to patient carried inside aircraft with field medics or
nurses providing patient care
The Huey Helicopter served as the blue print for BK 117 Civilian Aircraft
Modern day helicopter ambulance also comes in many differentshapes and sizes
Thank you Roy Morgan
Roy Morgan, Air Methods' founder, was the pilot who flew the first St. Mary's air
medical team Flight for Life, of Denver Co. established 1972
Flight For Life began with a single Alouette III
helicopter

World War II
At the beginning of World War II, the common belief was air
evacuation of sick and wounded was dangerous, medically
unsound, and militarily impossible.
The Army Medical Department did not believe the airplane was
a substitute for field ambulances, even when it was necessary
to evacuate casualties over long distances

Recent Statistics
After a spike in air ambulance crashes in the United States, the U. S. Government implemented more stringent regulations for operation of air medical services.
The Commission on Air Medical Transportation Systems (CAMTS) continues to review and implement standards focused on patient and flight safety.
CAMTS Accreditation is generally voluntary although some states require accreditation
No one holds more regard for safety of transport than the transport crew› Transport is an unstable environment many precautions are taken to
ensure safety
Crew members are experts in the realm of patient transport.
Decision on of mode of transport considers many factors beyond physician request› Crew configuration› Crew capabilities› Access to specialized equipment or treatments in transit› Time to complete transport› Time for patient out of hospital› Distance, terrain, physical environment› Appropriate utilization of resources
Flight Safety Tools and Procedures
Aircraft› TAWS› Weather Radar› Wire Cutters› Auto Pilot› NVG› Satellite Tracking
Crew› Helmets› Nomex flight suits› Radio communication between all crew and Flight Comms › Regular aircraft safety briefs› Regular Pilot check rides and simulator training
Procedures› Fire guard › Tail guard for hot load › Q 10 minute position checks› Weather check prior to mission acceptance regardless of weather
conditions

› Surfactent
› Blood
Distance / Environment
Not all patients flown are critical or time sensitive› Distance, a need to move (Thru put), or available resources contribute
to choosing air vs. ground transport› Remote, sparsely populated areas which may be inaccessible by road
for months at a time benefit from air ambulance transport
Fixed-wing vs. Ground› Cost difference
Rotor-wing vs. Fixed-wing› Cost difference
Medical Control
Crew skills set considerably greater than street medics or nurses with hospital ICU background› Allows ability to exercise more latitude in medical decision-making
Skills may include advanced treatment typically performed by physicians › EKG or x-ray interpretation leading to treatment plan determined by
crew
Some systems operate almost entirely off-line, using protocols› On line medical control accessed when protocols have been
exhausted

E How do we interact with other healthcare entities
Request for Service
It’s a pre hospital ambulance – › Scene call activation is as second responder, must be requested by
another entity › In North Carolina 911 centers will contact the service directly
Some areas have centralized dispatch
It’s an inter-facility ambulance –› Physician or designee contacts service for request to transport› Primary transport is from lower level of care to higher level of care› Back transport is from higher level of care to lower level of care, or a
lateral transfer Difference is applicable only for billing Carolina Air Care implemented Transport Coordinator function to interact
with UNC’s Transfer Center
Request for Service
Scene calls – goal is to dispatch closest available aircraft› How do we know which aircraft is closest and in service while
minimizing time to procure resource› Destination is to closest appropriate facility
Inter Facility – tends to be associated with hospital relationships, hospital systems, or perceived closest aircraft
What if there is no aircraft available› Program relationships› Search alternate resources
How does weather affect resource utilization› Front side or back side of weather?
Multiple Services Available
Co-Opetition vs. Competition › Air Medical Transport is becoming competitive› Over built in some regions› Collaborative relationships are essential
North Carolina Air Medical Association› Established 1986 by existing Hospital based flight programs in NC› NCAA sets an example in how other regions could operate› Mutual Aid agreement between agencies to cover transports unable to
be completed by requesting program
19 Hospital Affiliated aircraft – 1 EMS – 1 Military
Medical Transport has multiple levels of care available
Patient billing based upon level of care provided› Emergency or Non –Emergency indicates ambulance was
dispatched as soon as it was available or mission was pre-scheduled
› BLS – Basic Life Support – minimal treatment required
› ALS – Advanced Life Support – Advanced medical treatment required by one provider
› ALS 2 (a.k.a. Critical Care) – Advanced Life Support – Significant advanced medical treatment required by more than one medical provider, ALS procedures performed
› SCT – Specialized care or team – Specific team configuration required or utilization of highly specialized equipment
