When confronted by emergency situations, often our first impulse is to spring into action, offering assistance, first aid, a helping hand. But without proper first-response or medical training, that resilient, compassionate human spirit that drives us to aid our fellow human beings can end up doing as much harm as good. However, armed with even minimal emergency lifesaving knowledge anyone can render aid, improving victims’ chances of surviving the “golden hour” – those first 60 precious minutes that are critical for successful emergency treatment. Stefano Driussi is one of those trained first responders; as a Basic Life Support (BLS) instructor, he is well prepared to react when emergencies arise. Driussi is also a skilled software developer and one of the co-founders of Digitalapes, a successful .NET and J2ME application development house. When the company decided to add Windows Phone 7 to its platform repertoire, he began thinking of how he could best combine his basic life support skills with the team’s development expertise. An idea began to take shape for a Windows Phone 7 application that would help users to perform essential first aid in the case of an emergency.
