Spirometry a lung (or pulmonary) function test that measures how much air you can exhale. This asthma test confirms the presence of airway obstruction that improves with treatment, which is very characteristic of asthma, and can accurately measure the degree of lung function impairment. This test...

During spirometry, you exhale into a device that analyzes the amount and volume of airflow. One part of the test may be repeated after you are given a bronchodilator. This medication relaxes the muscles surrounding the airways. If airflow improves with a bronchodilator, it indicates that you ...
It has been proven that most of not all disease is caused by Acidic Waste that is not flushed out of the body daily (Google Dr Otto Warburg). Your body will die if you can not exhale the CO2 and bring in fresh Oxygen. All Cells produce waste and when you neglect the need of your ...
that carry air in and out of your lungs. If you have asthma, these tubes are inflamed, which causes swelling that narrows the passageway into your lungs. As a result, air has a harder time getting into your lungs when you inhale and out of them when you exhale, leaving you gasping, ...
Another method for diagnosing asthma is the peak flow test, which measures how fast you can exhale. This test uses a small handheld device to assess your peak expiratory flow rate (PEFR). To use a PEFR device: Check that the marker is at the bottom. ...
That happens because as the airways constrict, air whistles as it passes through the narrowed space. These symptoms may make a person feel like they’re running out of air. Yet counterintuitively, during an asthma attack, the inflammation can make it harder to exhale than inhale. Over time,...
When you exhale, air that is rich in carbon dioxide (CO2) passes out of your lungs, through your windpipe, and out your body through your nose and/or mouth. How Does Asthma Affect Breathing? During an asthma attack, airways become inflamed and sensitive. Swelling narrows the airways, making...
One test of lung function is called spirometry. You will take a deep breath and blow into a sensor to measure the amount of air your lungs can hold and the speed of the air you inhale or exhale. This test diagnoses asthma severity and measures how well treatment is working. ...
Lung Function Tests:Lung function tests are essential for diagnosing asthma. The most common test is called spirometry. It measures the amount of air a person can forcefully exhale and how quickly they can do it. Additionally, a bronchodilator reversibility test may be performed to assess whether...
