This video demonstrates a clear, step-by-step workflow designed to help healthcare professionals perform FeNO measurements accurately and efficiently in clinical settings. The video begins by introducing the device setup, showing how to properly connect the breathing tube, handpiece, and disposable mouthpiece to ensure a secure and hygienic testing environment.

Next, the video guides users through powering on the device and preparing it for measurement. Patient information, such as age and gender, is entered into the system before initiating the test. During this stage, the device automatically performs an ambient nitric oxide check, ensuring that environmental conditions are suitable for accurate measurement.

The core of the video focuses on the breathing procedure. The patient is instructed to inhale deeply and then exhale steadily into the mouthpiece while maintaining a consistent flow. Visual indicators on the screen help guide the patient to keep their breath within the optimal range, ensuring reliable test results. This step is critical, as controlled exhalation directly impacts the accuracy of FeNO readings.

Once the breath sample is completed, the device processes the data within seconds and displays the FeNO result clearly on the screen in ppb (parts per billion). The video highlights how this quick turnaround supports immediate clinical decision-making and enhances workflow efficiency.

Additionally, the video emphasizes hygiene and safety by demonstrating the use of disposable mouthpieces, reducing the risk of cross-contamination between patients. It also shows how users can repeat tests or start new measurements seamlessly, supporting continuous clinical use.

Overall, the video provides a practical and user-friendly overview of the Sunvou HA1101 and TM1101 systems, helping users gain confidence in performing standardized FeNO testing and ensuring consistent, accurate respiratory diagnostics in everyday practice.
