Lifelight is a digital technology that enables the measurement of patient vital signs: heart rate, respiratory rate, blood pressure and oxygen saturation in 60 seconds using just the camera built-in to an everyday device such as a smartphone, tablet or computer. Lifelight doesn’t need any medical specialist hardware such as blood pressure cuffs, it’s completely passive and non-contact, and it’s also simple to use and very fast. Its only requirement is that the patient remains in sight of the camera for at least 30 seconds, while the readings take place. What it does is detect micro-tonal skin colour changes that signal your vital signs.
