If you or one of your attendees have a medical emergency in flight, let's hope you're on a Virgin Atlantic plane. According to this article, the airline has implemented some pretty cool technology to link flights to medical help on the ground, allowing non-medical people to help the afflicted. From the article:
Tempus uses the satellite technology that operates Virgin Atlanticâ€™s onboard telephone system to transmit medical information such as pulse rate and blood pressure readings as well as video images to medical experts at the MedAire Centre in Phoenix, Arizona. The ground-based doctors can then diagnose the problem and advise the crew on the next course of action, enabling crew to use their medical training to assist the passenger.
