This handheld multi-vitals monitor developed by a Chennai-based start-up brings together a stethoscope, pulse oximeter and can double up as an ECG machine. The cordless device, which was showcased at the Tamil Nadu Global Investors Meet, can also measure blood pressure, sugar and temperature. This takes tele-consultation to a new level as doctors will be able to get vital data and hear heartbeats of patients in remote locations. NDTV’s Sam Daniel speaks to the GreenOcean team that developed this.
