Answers to key questions about N-Tidal Diagnose technology, performance, and implementation in your practice.
N-Tidal Diagnose -
point of care COPD diagnostic test
N-Tidal™ Diagnose is a breakthrough CE-marked point-of-care diagnostic solution for COPD, which combines the precise measurement of respiratory physiology using the N-Tidal™ medical device, and automated interpretation of the data using our diagnostic AI algorithms. From the start of the breath test, to accurate diagnosis with severity staging, in as little as 5 minutes.
Book a demoA unique COPD diagnostic solution
N-Tidal™ Diagnose is a regulated, secure class 2a medical
device diagnostic solution delivered as a service. It combines
state of the art hardware (N-Tidal™) with AI-powered
diagnostic software to deliver COPD diagnosis at the point of care
within minutes.
Leveraging a revolutionary new patented sensor technology,
N-Tidal™ Diagnose performs real-time geometric analysis of
CO2
breath waveforms to provide highly sensitive quantification of
lung function, from relaxed breathing.
Simple, connected handset
Patented, industry-leading sensor that captures high resolution respired CO2 data from just 75 seconds of relaxed breathing.
Automated data transfer and interpretation
Data is automatically uploaded via 4G networks in near-real time, processed into N-Tidal digital biomarkers and run through N-Tidal™ Diagnose AI algorithms.
Rapid, transparent diagnostic output
N-Tidal™ Diagnose AI algorithms automatically interpret the data and issue a diagnostic test report to the dashboard as a downloadable pdf report. No need for specialist interpretation.

When innovation changes the game
A new perspective on capnography
Capnography measures respired CO2 but hasn't traditionally been used to diagnose respiratory conditions, despite its known ability to detect airflow limitations and gas exchange. This isn't due to irrelevance but past technological limitations with CO2 sensor high-speed sampling and accuracy, automated connectivity and real-time signal processing. These are barriers that TidalSense's N-Tidal™ technology has now overcome.
What's new with N-Tidal™?
Novel sensor technology
Our sensor can detect subtle changes in CO2 accurately all the way to background levels of CO2, capturing physiologic signals previously too small to detect.
Advanced signal engineering
Our proprietary algorithms enhance and isolate clinically-relevant features in CO2 breath waveforms, removing noise and emphasising disease-specific patterns.
AI-powered analysis
Machine learning models trained and validated on thousands of datasets selectively identify waveform patterns associated with COPD that remove the need for manual interpretation and automate diagnostic reporting.
Diagnostic accuracy beyond severe COPD
Our technology detects COPD across all severity levels, not just advanced cases. Owing to the high signal resolution afforded by our sensor combined with our signal processing algorithms, our clinical validation has proven N-Tidal™ Diagnose's accuracy across all GOLD stages, that other methods may miss. It also effectively distinguishes COPD from other respiratory conditions.
N-Tidal™ Diagnose achieves 90% sensitivity, 88% specificity with Positive and Negative Predictive Values of 93%, offering clinicians diagnostic confidence.
