WARNING
• NEVER diagnose or treat a patient based only on the result from this device. ONLY a physician is
qualified to diagnose and treat patient’s respiratory disease.
• ONLY apply this device on a patient whose illness was diagnosed as bronchitis, bronchiolitis or
bronchial asthma.
• Consult with a physician before using this device. This device is intended to be used under the
direction of a physician or licensed healthcare professional.
• If a patient is having signs and symptoms of chest tightness, shortness of breath, coughing or
wheezing, a wheeze may not be detected because:
- the breathing sound is too loud or too soft;
- the wheeze is at extremely small amplitude, extremely short duration, extremely
high frequency or extremely low frequency;
- an asthma attack occurs without wheezing.
Always take action as prescribed by a physician, no matter what the result from this device is.
This device also may incorrectly detect any noise as a wheeze because various sounds are
occurring in patient's body such as:
- voice or cry of a patient;
- nasal obstruction sound;
- sputum sound etc.
• DO NOT use in case of severe asthma attack or respiratory failure. Consult with a physician
immediately.
• Take a measurement again if you are concerned about the result. This device can detect wheeze
only while taking a measurement. Wheeze can occur after taking a measurement. If you are still
concerned after taking a measurement again, consult with a physician.
• DO NOT use this device on a chest that is injured or that is under medical treatment.
• DO NOT disassemble or attempt to repair this device. This may cause an inaccurate result. This
