Breathing Test levels? (FEV1) What do they mean

[brians2000]

Does anyone know what these values mean in a breathing test

Height without Shoes (inches)
FEV1 Equal to or less than (L,BTPS)


60" or less
1.05


61"-63"
1.15


64"-65"
1.25


66"-67"
1.35


68"-69"
1.45


70"-71"
1.55


72" or more
1.65

The FEV1 is a respiratory test that measures the amount of forced expiratory volume that you can breath out in your best effort in one second (FeV1), measured in liters of air. The FEV1 is the most important measurement for the severity of chronic obstructive pulmonary diseases
such as emphysema, chronic bronchitis, asthma, and
bronchopulmonary dysplasia. The FEV1 would be decreased
when these medical conditions are present.

When you undergo the FEV1 test, you are asked to put on a nose clip, then take as deep a breath as possible, and then blow it out as hard and fast as you can through your mouth into a tube. The procedure may be repeated at least three times. If the test results are at least 70% of normal expected values, the test will end there. Otherwise, you will repeat it three times, after inhaling a bronchodilator drug to see if the results improve. If the person administering your spirometry test does not think you have put forth maximum effort, you may have to undergo repeat testing.

What you have shown in your quoted FEV1 values above, are the FEV1 test results that are at the higher end of what would satisfy the SSA medical listings for evidence of disability under 3.02 for COPD. For example, if you are 60 inches or less in height and your FEV1 value is equal to 1.05 liters of air or less, then you would be found to meet the SSA medical listing (3.02) for respiratory disease. This would be prima facie medical evidence of disability, and no further proof of medical disability would be needed. You should notice in the table that you quoted that taller people tend to have higher FEV1 values (more lung capacity), and therefore height is taken into account in the assessment.

You can read about the medical listings for respiratory disease at this site:

http://www.ssa.gov/disability/professionals/bluebook/3.00-Respiratory-Adult.htm

In particular, look at listing 3.02 on that website, which is the medical listing that involves the FEV1 values shown in your table for evidence of disabling chronic pulmonary insufficiency.

FEV is the volume of air that you exhale rapidly within one second. The important number would be the % of FEV. They use calculations based on age and weight and height and the % is the number that you are. 100% would be the average for your same age , weight and height. So if it said 70%, you would be 70% of what you should be.

I see that DE has gone into a much more detailed explanation while i was typing this.

FEV1 = Forced Expiratory Volume This is the amount of air you are able to exahle in one second after taking a deep breath. If your FEV1 is equal or less than the number listed for your height, this is considered to be of listing level severity.

I remember the technician telling me I was at 32% before the medicine and 35% after the meds. I wish this chart I put down had used percentages instead of values in liters. I don't know the value in liters I breathed that day.
