About Us

TidalSense, formerly Cambridge Respiratory Innovations, is a venture-backed respiratory technology company founded in 2013 and headquartered in Cambridge UK.

Our technologies are built on the foundation of our novel patented sensor technology, embedded within N-Tidal, which provides unprecedented insight into lung physiology through high accuracy, rapid sampled CO₂, unlike anything seen before in clinical medicine.

Our platform converts N-Tidal CO₂ data into over 80 sensitive respiratory biomarkers, in real-time, through analysis of waveform geometry, which fuel our AI diagnostic and monitoring technologies.
