What is TLco lung function?

A gas transfer test measures how your lungs take up oxygen from the air you breathe. The result of the test is called the transfer factor, or sometimes the diffusing capacity. A gas transfer test is sometimes known as a TLco test. TLco refers to the transfer capacity of the lung, for the uptake of carbon monoxide (CO).

What is the normal range for FEF 25 75?

The CV for FEF25–75 at age 5 to 6 years is 20%, corresponding to 60 to 140% predicted, and by age 50, the CV for FEF25–75 has widened to 30%, a normal range of 40 to 160%.

What does KCO stand for in lung function test?

Kco Kco=DLco/VA ( alveolar volume) Is volume standardized measure of Dlco Intrinsic property of alveolar-capillary membrane Kcois reduced in emphysema and intrathoraciccauses of restrictive lung disease]

What are the results of a lung function test?

The results of your lung function tests also help your doctor decide what kinds of medications and treatments you need. They also help your doctor determine how well your current treatments are working and evaluate the effectiveness of newly-prescribed medications.

How does the spirometry test predict lung function?

Basically, normal, predicted values are gained during population-based research studies of people with normal lung function. After you have your spirometry test, your doctor compares your test results to the normal, predicted values from people who are similar to you in age, height, weight, gender and ethnicity.

What are normal values for pulmonary function test?

Normal values for PFTs vary from person to person. The amount of air inhaled and exhaled in your test results are compared to the average for someone of the same age, height, sex, and race. Results are also compared to any of your previous test results. If you have abnormal PFT measurements or if your results have changed, you may need other tests.
