TidalSense (formerly CRI)

Company overview

The medtech company TidalSense, formerly Cambridge Respiratory Innovations (CRI), creates ground-breaking respiratory technologies.

TidalSense first received funding from BGF and Downing Ventures in December 2020, to fast-track research and development of its award-winning N-Tidal device.

The N-Tidal device is a first-in-kind, connected, handheld capnometer incorporating unique patented sensor technology, that can accurately measure carbon dioxide levels in exhaled breath during normal breathing. It helps medical professionals diagnose and monitor respiratory conditions.
