The accuracy of each of the 13 sleep study nights was analysed using the mean oxygen desaturation index (ODI)3% of all 14 nights as a reference. Multiple regression analyses assessed possible predictors for nigh
Study design and Methods: 40 OSA patients permanently living in Shangri-La, China, at 3200m, median (quartiles) age 47.0 (44.0;53.0) years, oxygen desaturation index 38.4 (34.2;52.3)/h were randomly assigned to receive nasal NOS and sham oxygen (ambient air), respectively, during one ...

Deep oxygen desaturations can also be observed in oximetry signal. In patients with severe obstructive sleep apnea, these desaturations are observed as a periodic oximetry signals where a low frequency component could be obtained as in Figure 5b. A recovery of the oximetry value is obtained shortl...

What Is the Oxygen Desaturation Index (ODI)? Treating Low Oxygen Saturation Generally speaking, an oxygen saturation level below 95% is considered abnormal. This should be evaluated by a healthcare provider. An oxygen saturation level below 90% requires emergency medical attention.8 ...
The same process likely occurs at sea level, but saturations are on the flat part of the oxyhemoglobin desaturation curve, and the change in saturation is not apparent. The appropriate timing to perform pulse oximetry is a focus of persistent debate in CCHD screening [1, 10]. When screening...
(as measured by 4% oxygen desaturation index, mean nocturnal oxygen saturation as measured by pulse oximetry, total sleep time with oxygen saturation as measured by pulse oximetry <90%, mean nocturnal transcutaneous carbon dioxide, and maximum nocturnal transcutaneous carbon dioxide), breathlessness as...
Similar analyses should be performed at other institutions and should explore specific factors within a racial and ethnic group that could put some patients at particularly high risk of oxygenation disparities, including skin tone, degree of desaturation, exposure to specific oxygen delivery devices, ...
oxygen desaturation (SpO2 ≤ 90%) occurred, flow rate was firstly raised up to 60 L/min and if saturation doesn’t recover over 95%, then FIO2was raised up to 100%. The upper limit of SpO2and flow rate is 100% and 60 L/min. However, if desaturation was accompanied by agitation...
