摘要

Background: Patients suffering from exercise-induced laryngeal obstruction (EILO) are subjected to several exhausting tests. We aimed to assess the feasibility of using a single test to obtain diagnostic measurements for maximum oxygen uptake (VO_(2)max) and exercise-induced laryngeal obstruction (EILO).Methods: Patients referred to the outpatient respiratory clinic at the University Hospital of Bispebjerg, Copenhagen with exercise-induced dyspnoea were evaluated for inclusion over 13?months. Eligible patients were aged 18–43?years, had a known EILO diagnosis (moderate or severe) and were inactive (self-reported activity) with less than 3?hours activity per week. In randomised order, all participants (n? =?11) underwent three tests: a VO_(2)max test with and without concurrent laryngoscopy. VO_(2)max and EILO values from the two testing methods were compared.Findings: There was no difference in VO_(2)max measured by ergospirometry with and without simultaneous continuous laryngoscopy during exercise (CLE) testing (mean difference ?22?ml O_(2)?min~(?1); 95% CI ?125 to 81?ml O_(2)?min~(?1); P? =?0.647). EILO scores obtained during the CLE testing on the treadmill versus CLE testing on the ergometer bike revealed identical supraglottic scores in nine of the 11 participants (82%) with substantial agreement between the two types of test (x ?=?0.71). Glottic scores were identical in six of the 11 (55%), showing moderate agreement between test types (x ?=?0.38).Conclusions: Based on our findings in inactive individuals, ergospirometry with laryngoscopy is feasible and well tolerated, yielding measurements for maximal oxygen uptake comparable to those of standard bike ergospirometry. Likewise, measurements of supraglottic EILO are comparable to those of the standard treadmill CLE test.
