Non-invasive high flow is a medical screening technique that is commonly used to check lung function. It detects the amount and flow rate of gas exhaled by a patient through the use of a device called a high-flow gas meter. Non-invasive high flow not only assesses lung function, but also helps doctors diagnose tracheal, bronchial and lung diseases.
Non-invasive high-flow technology detects the velocity and volume of airflow in the lungs, making it useful in the diagnosis of lung diseases such as asthma, COPD, and pulmonary fibrosis. It is also a safe method of testing because the noninvasive high-flow procedure causes no pain or discomfort to the patient.
Although the noninvasive high-flow test is very safe, there are still some things to keep in mind. Before performing the test, the doctor needs to check the patient's medical history and ask if there are any allergies or self-defense reactions. While performing the test, you should breathe normally and use the equipment properly as instructed by the doctor. In addition, non-invasive high-flow screening may not be appropriate for certain people, such as patients with obesity, mouth and nose disorders, lung infections, or other respiratory conditions. If you have any of these conditions, talk to your doctor about whether you are a good candidate for this test.
