In this video, we introduce the tidal FeNO test, a gentle and practical solution for measuring exhaled nitric oxide in patients who cannot perform traditional breathing maneuvers. The tidal test mode is designed especially for young children and individuals with limited breath control, offering a flexible and patient‑friendly way to assess airway inflammation using Sunvou’s advanced respiratory diagnostics.

You’ll first see an overview of the device setup and the unique tidal breathing method, where patients breathe normally into the sensor rather than sustaining a long, forceful exhalation. This approach allows multiple relaxed breaths over a short period, making it ideal for toddlers aged 0‑3 or older patients who struggle with standard online or offline sampling techniques.

The video then demonstrates step‑by‑step how to prepare the device, position the patient, and begin the tidal FeNO measurement. Clear visuals show the breathing interface and how the device collects consistent data from each breath. Sunvou’s intuitive design ensures that clinicians and technicians can perform the test with confidence, even in challenging patient scenarios.

You’ll notice how Sunvou technology seamlessly integrates into routine respiratory assessments, maintaining high reliability while accommodating real‑world clinical needs. The tidal mode is part of Sunvou’s broader FeNO testing ecosystem, which also includes bronchial, alveolar, and upper airway measurement options for comprehensive inflammation profiling.

By the end of the video, you’ll understand how the tidal FeNO test expands your toolkit for asthma management and inflammatory airway evaluation. Whether you’re working with pediatric patients or adults with limited breath control, this feature helps deliver accurate, reproducible results — reinforcing Sunvou’s commitment to innovative and accessible respiratory diagnostics.
