Spirometry

Spirometry is the first and most commonly done lung function test. It measures how much and how quickly you can move air out of your lungs. For this test, you breathe into a mouthpiece attached to a recording device (spirometer). The information collected by the spirometer may be printed out on a chart called a spirogram. The device that we use at the CLEAR Scoliosis Center of La Crosse is: EasyOne Plus - diagnostic

The more common lung function values measured with spirometry are:

  • Forced vital capacity (FVC). This measures the amount of air you can exhale with force after you inhale as deeply as possible.
  • Forced expiratory volume (FEV). This measures the amount of air you can exhale with force in one breath. The amount of air you exhale may be measured at 1 second (FEV1), 2 seconds (FEV2), or 3 seconds (FEV3). FEV1 divided by FVC can also be determined.
  • Forced expiratory flow 25% to 75%. This measures the air flow halfway through an exhale.
  • Peak expiratory flow (PEF). This measures how much air you can exhale when you try your hardest. It is usually measured at the same time as your forced vital capacity (FVC).
  • Maximum voluntary ventilation (MVV). This measures the greatest amount of air you can breathe in and out during 1 minute.
  • Slow vital capacity (SVC). This measures the amount of air you can slowly exhale after you inhale as deeply as possible.
  • Total lung capacity (TLC). This measures the amount of air in your lungs after you inhale as deeply as possible.
  • Functional residual capacity (FRC). This measures the amount of air in your lungs at the end of a normal exhaled breath.
  • Residual volume (RV). This measures the amount of air in your lungs after you have exhaled completely. It can be done by breathing in helium or nitrogen gas and seeing how much is exhaled.
  • Expiratory reserve volume (ERV). This measures the difference between the amount of air in your lungs after a normal exhale (FRC) and the amount after you exhale with force (RV).

Testimonials

"I struggled with back pain for 4 years prior to seeking help for my Scoliosis. I decided after visiting Dr. Breidenbach that it was worth the financial commitment and time dedication to go through the CLEAR scoliosis treatment. My pain throughout the 4 years was more of an extreme discomfort and occasional immobilization from immense pain spikes. My biggest problems occurred when I was on my feet for long periods of time, sitting for too long, and any type of consecutive lifting. It was emotionally draining because no matter what stretches, exercises or methods I tried, nothing seemed to work.
My pain level now, after completing the 4 month treatment program and continuing my at-home protocol, is extremely low and very manageable. The only time I experience discomfort is after very long days on my feet, which still only results in minor soreness. I am so much happier and less stressed about everyday activities, and can do so much more than before. My Cobb angle also improved from 13.8 degrees down to 4 degrees (71% improvement).
I would suggest the CLEAR scoliosis Center of La Crosse to anyone that experiences pain and dysfunction with scoliosis. The whole staff was extremely kind and supportive, while also maintaining a high level of professionalism. I am so happy to have a normal life without the constant annoyance and discomfort of pain from scoliosis.
