Abstract: In this prospective volunteer validation study, a strong and positive correlation between PaO2 and ORi was found, together with a good trending ability. Based on these data, the future use of ORi as a continuous noninvasive monitoring tool for assessing oxygenation status in patients receiving supplemental oxygen might be supported.

“…Therefore, if our ORI target was <0.21, the results may have been different. A lower ORI target may be feasible because Pao 2 in healthy adults at sea level is 88 to 100 mm Hg, 21,28 and an ORI of 0.00 to 0.11 corresponded to a Pao 2 of 100 mm Hg in our data and previous reports. 20,21 One problem is that because the ORI does not have negative values, targeting an ORI close to 0 may not detect hypoxemia.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…However, we believed that setting the ORI target as 0.4 for intervention initiation would lead to frequent disruption of the surgical procedure during airway surgery. In addition, previous studies have suggested an ORI target of 0.21 to prevent hypoxaemia 11–13,19 . However, we found that setting the ORI target as 0.2 for initiating interventions would have no effect on the incidence of oxygen desaturation below 90%.…”

[11][12][13]19 However, we found that setting the ORI target as 0.2 for initiating interventions would have no effect on the incidence of oxygen desaturation below 90%. This suggests that future studies should carefully consider the selection of the ORI target for initiating rescue interventions, taking into consideration both the prevention of hypoxaemia and the practical aspects of the surgical procedure.…”

“…They found that when paO 2 was <100 mmHg, ORi TM was 0.00 in 99% of the data points, in the other hand, when ORi TM was 0.00 paO 2 was <100 mmHg in 56%. When studying within the ORi TM sensitive range the concordance rate was 94% (92%–96%), which confirms a strong positive correlation 73 …”
