Time windows of peak obstruction in individual tests
| Airway location | Rest | Peak work capacity % | Recovery time s | |||||||
| 25 | 50 | 75 | 90 | 100 | 15 | 30 | 45 | 60 | ||
| Glottic (n=65) | 2 | 0 | 0 | 2 | 7 | 44 | 18 | 10 | 9 | 7 |
| Supraglottic (n=68) | 1 | 0 | 1 | 5 | 20 | 50 | 25 | 14 | 11 | 7 |
Data are presented as n continuous laryngoscopy during exercise tests in which the specific time windows were rated as maximally obstructed. In tests with more than a single window scored with observed maximal obstruction, each window is recorded. Patients with no observed obstruction by a specific structure are not included.
