| Air Ambulance Services |
The healthcare sector has evolved by leaps and bounds over the last few
decades. With advanced medical facilities and cutting edge technologies
available, life expectancy has increased manifold across the world. However,
there are still situations where critical patients need urgent medical
attention which routine ambulance services are not equipped to provide. This is
where air ambulance services have emerged as saviors, helping transport
critically ill or injured patients over long distances in minimum possible
time.
History and Evolution
The concept of air ambulance is not new. The earliest known air ambulance
service dates back to 1912 during the Balkan Wars when aircraft were used to
evacuate wounded soldiers from remote locations. However, it was only in the
1950s that dedicated air ambulance programs were established. Over the decades,
these services kept expanding with improvement in aviation technologies as well
as emergence of concepts like Critical Care Transport. Today, air ambulances
utilize advanced helicopters and jets outfitted with ICU-level care to reach
patients in far-flung areas within short time.
Types of Aircraft Used
Depending on the type and severity of medical emergency, air ambulance services
utilize different aircraft best suited for the job:
- Helicopters: Being highly maneuverable, helicopters are best for transporting
patients from accident sites, disasters areas etc which may not have proper
helipads. They can land almost anywhere and there are variety of models used
ranging from light single engine to large twin engine helicopters.
- Fixed Wing Aircraft: For long distance inter-hospital transfers especially
over water bodies or remote regions, fixed wing aircraft like jets and
turboprops provide faster travel. They have more seating capacity and range.
However, they require proper runways for take-off and landing.
- Drones: With advancements in drone technologies, there is exploration of
their potential roles like delivery of emergency supplies, portable defibrillators,
blood etc. However, legal and safety aspects need further research before
patient transport.
Crew and Facilities
The medical crew onboard Air
Ambulance Services is as critical as the aircraft itself. A typical
crew consists of highly trained ICU nurses, respiratory therapists, paramedics
and emergency room physicians who can continuously monitor the patient and
perform emergency procedures en-route if needed.
The aircraft interiors are fully equipped with lifesaving medical devices like
ventilators, defibrillators, pulse oximeters, EKG monitors etc along with fully
stocked crash carts and teams prepared for any medical exigency during flight.
Specialty treatments like blood transfusions, administering medications through
intravenous or intraosseous lines can also be continued. Stable ICU level care
is thus maintained throughout the air travel.
Services Provided
Air ambulance services respond to a variety of time-critical medical and trauma
cases:
- Intensive Care Transfers: This includes transferring critically ill patients
between hospitals, those on ventilator support or having sustained major
injuries/organ failures etc.
- Scene Calls: Direct responses to accident sites, disaster locations or areas
otherwise inaccessible by road to quickly evacuate patients.
- Organ Transplant Shuttling: Urgent transportation of donor organs or patients
for transplant procedures over long distances.
- Medical Evacuations: Vacating patients from remote/offshore locations like
oil rigs, cruise ships or natural calamity affected zones.
- Specialty Care Transfers: Shuttling of patients needing specialized
treatments available at tertiary medical centers like open-heart surgeries,
neurosurgeries, burns care etc.
Coverage Networks and Response Times
Leading air ambulance service providers have developed nationwide and in some
cases global coverage networks through partnerships. They aim to reach any
location within a service area within average response time of 60-90 minutes
considering all factors like aircraft preflight checks, team mobilization etc.
Through advanced communication systems, they also work closely with local EMS
and hospitals for seamless handover of patient care.
Costs Involved
While air ambulance services undoubtedly save many critical lives, the costs
involved can run into hundreds of thousands depending on the aircraft used,
medical resources deployed, service area, insurance coverage etc. However, most
agree that the high costs, though difficult initially, are outweighed by the
immense benefits of emergency medical air transport. Many service providers
also offer memberships and air medical insurance plans to make services
affordable for broader population.
Future of Air Ambulances
With rapid innovations taking place in aerospace, telemedicine and other
supporting technologies, the future looks bright for air ambulances to reach
even greater heights. Integration of Internet of Things, robotics, artificial
intelligence with emergency medical response holds immense potential. Concepts
like autonomous air ambulances, virtual ICU controls, delivery drones can
further expedite pre-hospital and inter-hospital care. Other frontier areas
being explored are development of super-agile VTOL aircraft, airships for
extended range transports. Overall, air ambulance services are surely
transforming the critical care landscape providing golden hours to patients in
remote corners worldwide.
Air ambulance services have come a long way since their inception and
established themselves as indispensable tools for emergency medical response.
Their specialized roles in expediting transportation of critically ill patients
can make difference between life and death. With continuous improvements and
innovations, these services will keep saving more lives and expanding access to
critical care in remotest parts of the world.
