WebApr 26, 2024 · An RD episode was defined as: respiratory rate ≤ 5 breaths/min (bpm) for ≥ 3 minutes, oxygen saturation (SpO 2) ≤ 85% for ≥ 3 minutes, end-tidal carbon dioxide (EtCO 2) ≤ 15 or ≥ 60 mm Hg for ≥ 3 minutes, apnea episode lasting > 30 seconds, or any respiratory opioid-related adverse event. WebSep 20, 2024 · Responders to oxygen therapy were defined as individuals with ≥50% reduction in oxygen desaturation index (ODI) on postoperative night 1 versus preoperative ODI. In total, 624 out of 823 patients with unrecognized OSA required oxygen therapy.

WebOct 1, 2024 · Polysomnography (PSG) type I, the gold standard for the diagnosis of OSA, is expensive and difficult to access by low-income populations. In this study, we aimed to verify the accuracy of the oxyhemoglobin desaturation index (ODI) in comparison to the apnea-hypopnea index (AHI) using a portable monitor. WebOxyhemoglobin desaturation represents an important clinical consequence of SDB.

Oxyhemoglobin - an overview ScienceDirect Topics
WebIn total, we analyzed 892 severe desaturations. The mean time from oxygen saturation peak to the oxygen saturation nadir (desaturation) was 43.6 (±3.8) seconds, whereas the mean time from oxygen saturation nadir to peak oxygen saturation (resaturation) was 14.0 (±6.9) seconds, thus taking one-third of the time as the desaturation episode. WebAbnormal oximetry was defined as >5 min with SpO 2 < 90% and/or an oxyhemoglobin desaturation index (ODI4) >5. Comparative analysis of patients with normal and abnormal overnight oximetry was performed using Fisher Exact and Wilcoxon signed-rank test. ... 52% had frequent desaturation events, and 43% had both. No significant differences existed ... WebThree kinds of oxyhemoglobin indexes, including the oxyhemoglobin desaturation index (ODI), time-domain index, and frequency-domain index, were used.
