Spirometry :
The most common test that one applies in an effort to determine lung functions is the setting up of the volumes of air taken in and exhaled along with the speed of such, which known as spirometry. Through such a setup, doctors can trace and monitor patients who have varied kinds of diseases affecting their breathing. This includes diseases like asthma and COPD while also all other kinds of diseases present in the lungs. You are encouraged to take deep breaths in and then blow as vigorously and rapidly as possible into an instrument known as a spirometer. It measures the volume of air that you blow out, but it also measures the rate at which that happens. Other measurements include FVC, which stands for total volume of air that can be expelled from the lungs, as well as FEV1, or how much of that can be forcefully exhaled within one second. Results from the test can even be used to diagnose whether the lung is healthy or not, so the effectiveness of the treatment can be gauged. The test is almost painless and quite efficient. It usually takes about 15 minutes and is performed in the doctor's office or hospital. A test of spirometry or spirometry is non-invasive and painless because no surgical procedure and injection of needles are required. The conditions that need to be observed before the test is administered might include the avoidance of certain medication or the activities such as smoking or intense exercise that could be assumed to interfere with the result. Spirometry is generally an excellent tool in understanding and managing respiratory health.
