Abstract Introduction The oxygen desaturation index (ODI) quantifies the number of desaturations per hour sleep and is a valuable parameter in diagnosing sleep-related breathing disorders. While oximetry alone insufficient for an accurate diagnosis, it provides meaningful insights Obstructive Sleep Apnea (OSA) ODI has been shown to correlate with Apnea-Hypopnea Index (AHI). close relationship b...

58 patients who underwent on-pump coronary artery bypass graft surgery were evaluated for changes in regional cerebral oxygen saturation (rSO2) measured by near infrared spectroscopy (NIRS). If rSO2 during the operation fell to more than 20% under the baseline, standardized interventions were undertaken to maintain rSO2. Despite those interventions, in some cases we observed inability to mainta...

STUDY OBJECTIVES Some respiratory patients exhibit oxygen desaturation during rehabilitative walking but not during maximal cardiopulmonary exercise testing (CPET). We evaluated exercise-induced desaturation during 6-min walk testing (6MWT) in comparison with CPET in patients with COPD and determined the reproducibility of the phenomenon. PATIENTS We tested 80 consecutive patients with COPD (...

Superselective ophthalmic artery injection of the chemotherapeutic agent is a new treatment option for advanced retinoblastoma.[1] We present case severe bronchospasm with loss tidal volume and oxygen desaturation in an infant during catheterization under general anesthesia.

In Duchenne muscular dystrophy (DMD) nocturnal oxygen desaturation occurs during rapid eye movement (REM) sleep. Polysomnography, which requires hospital admission, will detect sleep-related breathing abnormalities. In order to avoid the inconvenience of hospital admission for the disabled patient, we investigated overnight oxygenation in ten boys with DMD by domiciliary oximetry. In four boys ...
