| Best for | Exercise-induced bronchoconstriction monitoring |
For patients with exercise-induced bronchoconstriction, the Wellue O2Ring provides continuous SpO₂ monitoring during exercise without the interference of a fingertip clip. The ring form stays securely during movement, vibrates silently when SpO₂ drops, and records the entire exercise session. Post-exercise review shows exactly when SpO₂ dipped and by how much — objective data for physician discussions about pre-exercise bronchodilator timing.
