Spirometry is a test to check the condition of the lungs. It is a simple procedure in which a person is asked to breathe out into a machine. This helps to determine the abnormality from the normal spirometry values for a patient. A spirometry test is performed on a patient with wheezing, shortness of breath, or cough.
What is a Normal Reading on a Spirometer?
The normal spirometry values by age would differ from person to person, as age is not the only criterion. Before the test is run on the patient, the doctor calculates the normal result for the person based on his age, height, race, and gender.
Spirometry results depend on two factors. The first is FVC, or the forced vital capacity, in which a person needs to breathe out in a machine after breathing in. The results are compared to the normal results calculated by the healthcare provider. If the result is low, it shows the possibility of restrictive lung disease.
The second factor for normal spirometry levels is to measure FEV1. In this test, the patient is asked to breathe out in one second. This is again compared to the normal result. A low result shows that there is trouble or obstruction in the breathing of the patient.
To check the normal functioning of the lungs, a ratio is calculated, which is FEV1/FVC. This helps to determine lung function. A higher ratio shows healthy functioning of the lungs, and a lower ratio shows obstructive breathing.
Conclusion
The spirometry test may indicate a serious disease that requires further investigation and even hospitalisation. Therefore, it is advisable to get health insurance to cover healthcare expenses related to doctor consultations, tests and medicine.
