This test helps measure the amount of air you inhale and exhale. It allows doctors to know your rate of airflow and lung size when you breathe. Here, you sit in front of a machine and breathe into the attached mouthpiece. The mouthpiece snuggly fits on your face to prevent leakage. A clip is placed on your nose to ensure you do not exhale through your nose.
Then, you breathe into the machine. The technician may instruct you to take deep or short breaths. The lab technicians may also ask you to drink medicine to open your airways. Then, you have to breathe into the mouthpiece again. This checks the effect of the medicine on your lungs.
This test assesses the alveoli health. Alveoli are the small air sacs present in the lungs. They are responsible for getting oxygen from the air into the blood.
Here, you inhale various gases like helium, carbon dioxide, and oxygen. You breathe through a tube, and the attached machine analyzes how your body reacts to these gases.
This test helps find the reason for symptoms like shortness of breath. You have to walk on a treadmill or ride a stationary bike while breathing into a machine in this test. Doctors measure the impact of exercise on lung health in this test.
This test measures the level of oxygen in the blood. It does not involve any breathing. Instead, they fix a small device to your finger or earlobe. The device measures the amount of oxygen in your blood.
Doctors will compare your results against the averages of people with similar attributes. These attributes include age, height, and sex. If the results are within the normal range, then you have nothing to worry about. But, if the results are positive, doctors may order more tests to confirm the diagnosis. Test results vary across people, and only doctors can help explain your results.
