Pre-hospital emergency medical care
London's Air Ambulance Charity has been at the forefront of innovation in pre-hospital emergency medical care since its inception in 1989. The service has adopted elements of medical, military and aviation culture to deliver the highest standards in intensive care to the roadside. The governance system and

s (SOP) developed by the organisation are seen as a benchmark for other air ambulances across the world.
London's Air Ambulance carries a senior doctor in addition to a paramedic at all times, providing a 24/7 advanced trauma care outside of hospital, provide general anaesthetics on scene, and carry blood on board and administer blood transfusion on the roadside. From 2018, a consultant in pre-hospital emergency medicine will be present on most shifts, in addition to the other physician and paramedic.
In 2014, London's Air Ambulance performed the first pre-hospital
resuscitative endovascular balloon occlusion of the aorta (REBOA). Other key treatments performed by the service include surgical chest draining (thoracostomy), surgical and non-surgical rapid sequence induction (RSI), pelvic splinting (crucial to prevent blood loss in high impact crashes and crush injuries), advanced pain relief and sedation. The service started a trial of a portable brain scanner which can detect blood clots on the brain in April 2015.
Aircraft

The service's first helicopter was an
Aérospatiale SA 365N Dauphin. Built in 1982, it was registered G-HEMS, and delivered in December 1988, in time for the launch of the service in 1989. It initially wore a white livery, but was repainted several times, eventually into a red livery following sponsorship by

MD Helicopters MD 902 Explorers replaced the SA365N, they carried the registrations G-EHMS and G-LNDN. Both wear the same red-based livery, with green and yellow flashes, and are identical in model, equipment and crew. Typically only one helicopter was operational per day the other acts as a spare in case of break down, maintenance or, in a major incident, both helicopters are able to deploy. The helicopters usually cruised at , at an altitude of anywhere between . A regular fuel load, around , allowed for one hour's flying time.
Following a children's competition, the two helicopters were given names which were displayed on the side of each aircraft. In February 2016, G-LNDN was named ''Walter'' after the winning entrant's grandfather, whilst G-EHMS was named ''Rowan'' in April 2016 after the winning entrant's sister.
G-EHMS ''Rowan''
G-EHMS was built in 2000 and entered service in October of the same year, replacing the earlier SA 365N Dauphin 2.
