NESOI-2: Non-invasive Early Oxygen- Reserve-index (ORI) Determination to Prevent Hypoxaemia During Endotracheal Intubation
Study Details
Study Description
Brief Summary
The purpose of this study is to determine whether ORI monitoring increases the lowest oxygen saturation level during the interval between the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) and the end of the second minute after successful ETI.

Detailed Description
The trial population will be adults (18 years of age or older) who need endotracheal intubation while hospitalized in ICU
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Experimental group (ORI) ORI and SpO2 monitoring values during preoxygenation of patients will be provided to investigator to determine anaesthesia induction initiation. Anesthesic induction is provided at least 3 min of preoxygenation and after 1 min at ORI > 0.6 |
Other: Unblinded ORI values
ORI and SpO2 monitoring will be performed using Masimo Rad 7 and both values will be provided to investigator
|
| Other: Standard of care (SoC) group Only SpO2 values during preoxygenation of patients will be provided to investigator to determine anaesthesia induction initiation. Anesthesic induction is provided at least 3 min of preoxygenation |
Other: Blinded ORI values
ORI and SpO2 monitoring will be performed using Masimo Rad 7 and only SpO2 values will be provided to investigator

Outcome Measures
Primary Outcome Measures
- Determine whether ORI monitoring increases the lowest oxygen saturation level during ETI [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until the end of the second minute after successful ETI]
Lowest oxygen saturation is monitored by Masimo Rad7 oximeter during ETI in Experimental and Control groups
Secondary Outcome Measures
- Determine whether ORI monitoring increases the lowest oxygen saturation level according to local oximeter. [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until the end of the second minute after successful ETI]
Lowest oxygen saturation monitored by local oximeter during ETI in Experimental and Control groups are compared to values monitored by Masimo Rad7 in same conditions
- Determine whether ORI monitoring increases the lowest oxygen saturation level during ETI in "Body Mass Index (<30 or ≥30)" subgroup [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until the end of the second minute after successful ETI]
Lowest oxygen saturation is monitored by Masimo Rad7 oximeter during ETI in "Body Mass Index" subgroup
Other Outcome Measures
- Determine whether ORI monitoring increases the lowest oxygen saturation level during ETI in "Reason for ETI (hypoxaemia/other)" subgroup [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until the end of the second minute after successful ETI]
Lowest oxygen saturation is monitored by Masimo Rad7 oximeter during ETI in "Reason for ETI (hypoxaemia/other)" subgroup
- Determine whether ORI monitoring increases the lowest oxygen saturation level during ETI in "Shock/No shock (at inclusion)" subgroup [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until the end of the second minute after successful ETI]
Lowest oxygen saturation is monitored by Masimo Rad7 oximeter during ETI in "Shock/No shock (at inclusion)" subgroup
- Determine whether ORI monitoring increases the lowest oxygen saturation level during ETI in "Difficult Intubation (yes or no)" subgroup [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until the end of the second minute after successful ETI]
Lowest oxygen saturation is monitored by Masimo Rad7 oximeter during ETI in "Difficult Intubation (yes or no)" subgroup
- Determine whether ORI monitoring increases the lowest oxygen saturation level during ETI in "ORI threshold (<0.6 or ≥0.6)" subgroup [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until the end of the second minute after successful ETI]
Lowest oxygen saturation is monitored by Masimo Rad7 oximeter during ETI in "ORI threshold (<0.6 or ≥0.6)" subgroup
- Assess safety of ORI monitoring [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until the end of the second minute after successful ETI]
Occurrence of at least one severe life-threatening complication (death, cardiac arrest, arterial systolic pressure <90 mmHg, and/or SpO2<80%) and occurrence of each are assessed in Experimental and Control group
- Assess efficacy of ORI monitoring on ICU mortality [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until discharge from intensive care unit or up to 28 days]
ICU mortality is assessed in Experimental and Control groups
- Assess efficacy of ORI monitoring on 28-day mortality [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until day 28]
28-day mortality is assessed in Experimental and Control groups
- Assess efficacy of ORI monitoring on ICU stay length [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until discharge from intensive care unit or up to 28 days]
ICU stay length is assessed in Experimental and Control groups
- Assess efficacy of ORI monitoring on hospital stay length [From the first laryngoscopy (defined as introduction of the laryngoscope into the mouth) until discharge from hospital or up to 28 days]
Hospital stay length is assessed in Experimental and Control groups
- Assess efficacy of ORI monitoring on Mean Cognitive Core at day 28 (modified Telephone Interview for Cognitive Status) [Day 28]
Mean Cognitive Score at day 28 using modified Telephone Interview for Cognitive Status is assessed in Experimental and Control groups Values range from 0 to 43, with higher scores indicating better cognition
