It is difficult to estimate the number of lives saved by AI, partly because there are so many ways in which this can be achieved and partly because the number is increasing all the time. One significant way that AI can save lives is through wearable devices. According to MedTech Europe, AI could be saving between 380,000 and 403,000 lives each year in Europe alone. This is predominantly through wearable devices (up to 313,000 lives), followed by use in monitoring (42,000) and imaging (41,000).
