Supported by leading clinicians

"We have run several clinical studies with the N-Tidal on patients with severe asthma and other respiratory disorders. I believe that TidalSense's technologies have the potential to transform the way we diagnose and treat many of these respiratory conditions."

"60% to 70% of patients with COPD are undiagnosed and many are misdiagnosed or diagnosed late. This is a massive clinical problem. N-Tidal is a really exciting solution to this problem and if it becomes part of the annual physical, doctors will be able to monitor their patients more effectively and pick up early disease that may have been missed in the past. I think that N-Tidal’s high patient acceptance and ease of use means that it’s going to have a big effect clinically."
