Repeat spirometry3
  • 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. (ssa.gov)
  • If you used a bronchodilator before the test and your FEV 1 is less than 70 percent of your predicted normal value, we still require repeat spirometry after inhalation of a bronchodilator unless the supervising physician determines that it is not safe for you to take a bronchodilator again (in which case we may need to reschedule the test). (ssa.gov)
  • The prebronchodilator response and postbronchodilator response maneuver involves a baseline spirometric value compared with a postbrochodilator spirometric value (ie, a repeat spirometry 15 min after 2-4 inhalations of albuterol). (medscape.com)
