In daily life, many people are troubled by cough, some even frequent attacks, long treatment difficult to heal. Cough is a very common clinical manifestations, many diseases can lead to cough, its incentives are more complex. If we want to subdivide the causes of each cough one by one, we often need to use many testing methods to clarify, such as lung function, chest imaging, etc. However, even with these tests, some patients' coughs still cannot be diagnosed. You can use it at this time.PHENODetection.

1. what is nitric oxide(FENO) testing?

The main components of the gas exhaled by the human body are nitrogen, oxygen, and carbon dioxide, but in fact there is another important gas molecule, nitric oxide(NO)。NOIt is a colorless and highly fat-soluble small molecule gas and one of the most important endogenous regulatory molecules in the human body. Breathing gasNOIt is mainly used to diagnose airway inflammation, optimize anti-inflammatory treatment and monitor the risk of morbidity. The results are objective and easy to understand, and the value effect is significant for the management of airway diseases such as asthma, chronic obstructive pulmonary disease and chronic cough,Welcome by doctors and patients.

Patients with indications of recommendFeNODetection. Symptoms such as recurrent wheezing, shortness of breath, chest tightness and cough, mostly at night or in the early morning irritating dry cough (this part of the patients ifFeNOhigh value, indicating a significant effect of hormone therapy); patients with chest tightness as the only symptom (chest tightness variant asthmaCTVAThe investigation of); Need to evaluate the condition or provide clinical diagnosis basis (FeNOcan provide evidence of asthma diagnosis); assess efficacy or compliance (patients with improved inflammationFeNOwill decrease, patients with good complianceFeNOThere will also be persistent reduction); Patients with allergic rhinitis cannot cooperate with cough and asthma patients who complete other tests such as lung function.

2. recommend detection scheme

Respiratory nitric oxide (NO) Tester helpsPHENOThe monitor measures the patient's breathing.NOThe concentration. At present, Shenzhen Technology Co., Ltd. recommend a British alpha nitric oxide sensorNO-B4.NO-B4is a high-resolution sensor that can detect5ppbofNOGas, with high stability, fast response, good linearity and so on. Very suitable for medical mouth breathing gasNOThe detection.
