Welcome to the official Sunvou CA2122 FeNO video – your complete demonstration of how Sunvou’s all‑in‑one respiratory analyzer brings multi‑level nitric oxide testing into everyday clinical practice. This video walks through the full capabilities and workflow of the CA2122 FeNO device, showing how one system can perform a range of measurements to assess airway inflammation.

You’ll first see how the device handles bronchial FeNO (FeNO50) measurements, which help clinicians understand inflammation in the larger airways. The video then moves into alveolar nitric oxide (FeNO200 / CaNO) testing, offering insights into small airway involvement that’s essential in complex respiratory evaluations.

Next, the video introduces nasal nitric oxide (FnNO) testing, giving a complete picture of upper airway health. You’ll see how the system supports online testing with direct connection as well as offline measurements using transferrable sampling bags when direct patient testing isn’t possible.

A highlight of the demonstration is the tidal breathing mode – ideal for pediatric patients or individuals who can’t perform a controlled exhale. This mode shows how Sunvou has designed the CA2122 to be accessible and practical for diverse patient needs, improving measurement success even when standard protocols are challenging.

Throughout the video, the user experience is emphasized: from selecting test types and switching between modes to seeing how results are captured. The intuitive workflow simplifies respiratory assessment while ensuring reliable and repeatable results.

By combining multiple test methods in a single platform, the Sunvou CA2122 FeNO device helps healthcare professionals obtain a more comprehensive understanding of respiratory inflammation and make informed clinical decisions with confidence.
