Quizplus · Accepted Answer

According to the ATS-ERS standards, the technologist should perform at least three acceptable and repeatable maneuvers, and report the highest FEV1 and FVC values from any of the acceptable maneuvers. In this case, the results are all within 150 mL of each other, but performing another maneuver may help to ensure that the values are truly repeatable and acceptable. Therefore, the best choice is to perform another maneuver.
