During testing, if your FEV 1 is less than 70 percent of your predicted normal value, we require repeat spirometry after inhalation of a bronchodilator to evaluate your respiratory disorder under these listings, unless it is medically contraindicated.Wheezing by itself does not indicate that you are not medically stable. Experiencing, or within 30 days of completion of treatment for, an acute exacerbation (temporary worsening) of a chronic respiratory disorder.Experiencing, or within 30 days of completion of treatment for, a lower respiratory tract infection.Within 2 weeks of a change in your prescribed respiratory medication.Examples of when we would not consider you to be medically stable include when you are: You must be medically stable at the time of the test.We have the following requirements for spirometry under these listings:.We will not purchase spirometry for children who have not attained age 6. Regardless of whether the values are from the same forced expiratory maneuver or different forced expiratory maneuvers. We use your highest FEV 1 value to evaluate your respiratory disorder under 103.02AĪnd 103.04A, and your highest FVC value to evaluate your respiratory disorder under 103.02B, The total volume of air that you exhale during the entire forced expiratory maneuver is the FVC. The volume of air you exhale in the first second of the forced expiratory maneuver is the FEV 1. Spirometry, which measures how well you move air into and out of your lungs, involves at least three forced expiratory maneuvers during the same test session.Ī forced expiratory maneuver is a maximum inhalation followed by a forced maximum exhalation, and measures exhaled volumes of air over time.What is spirometry and what are our requirements for an acceptable test and report? The imaging must be consistent with the prevailing state of medical knowledge and clinical practice as the proper technique to support the evaluation of the disorder.Į. Imaging refers to medical imaging techniques, such as x-ray and computerized tomography.If you use supplemental oxygen, we still need medical evidence to establish the severity of your respiratory disorder.We may not need all of this evidence depending on your particular respiratory disorder and its effects on you. Other relevant laboratory tests, and descriptions of any prescribed treatment and your response to it. The results of imaging (see 103.00D3), spirometry (see 103.00E), Medical evidence should include your medical history, physical examination findings,
