London's air ambulance service typically sees around 2,000 patients per year, responding to around two stabbings per day on average. The summary describes a case where a 45-year-old man was stabbed once in the chest and the timeline of events from the initial 999 call to his transport via air ambulance to a major trauma center within 62 minutes, including the helicopter's response and on-scene treatment. Future developments discussed include reducing delays from rendezvous points and improved early cardiac monitoring transmitted from the scene.
