Personal Capnometer

The N-Tidal Handset by TidalSense is a novel handheld 4G-connected capnometer that works in combination with TidalSense’s cloud-based diagnostic and monitoring software. It works by measuring the amount of CO2 in the patient’s breath during relaxed tidal breathing for approximately 1 minute. Patients breathe in and out through a mouthpiece which, together with the RESPA, comprise the replaceable breath pathway.

Our subsidiary, Wideblue, has been TidalSense’s design and development partner for the N-Tidal Handset. From initial concept design, prototyping, design updates, Design for Manufacturing (DFM), and set up the supply chain for volume manufacturing.

Wideblue carried out the infra-red optical design for the CO2 sensor, the removable breath tube with infra-red windows, assisting in the patent prosecution with TidalSense. They designed and developed the electronics and initial control firmware, designed the user interface and intuitive ergonomic design of the handset, as well as prepared the packaging and accessories. This product was awarded two European Product Design Awards.
