The parameters that are used to summarize sleep disordered breathing include the obstructive apnea index, apnea hypopnea index and hypoventilation (as defined above). In addition, oxygen desaturation index (number of 3% or more desaturations/hour), duration of oxygen saturation below 90% and oxygen...
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 ...
(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...

Minor artifacts in the oxygen saturation trace occurred in 28 patients, and major artifacts preventing interpretation of the oxygen saturation occurred in 10 patients. There was no correlation between the changes in oxygen saturation observed and the age, weight, height, body mass index, physical ...
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 night-to-night variability. Results 103 patients underwent in-hospital RP. Using only the...
34 Low-dose oxygen supplementation may not be sufficient to prevent severe desaturations; both the SOS Pilot15 and this trial found no significant difference in severe desaturations between the treatment and control groups. A small (N = 46) nonrandomized study comparing high-flow oxygen ...
Oxygen saturationis obtained through pulse oximetry and is used to assist with scoring hypopneas when there is at least a 3% or 4% oxygen desaturation (depending on whether the recommended AASM or acceptable scoring criteria is used) associated with the respiratory event (Berry et al., 2017)....
