Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Evaluation of SpO₂ Resaturation Following Voluntary Apnea | From enrollment to the end of the inclusion, estimated at approximately 10 months from the start of enrollment | To characterize the temporal behavior of a modern finger pulse oximeter during voluntary apnea in healthy volunteers, with a particular focus on the delay (in seconds) between physiological reoxygenation and displayed SpO₂ (Time interval in seconds between the first breath following apnea and the first increase in SpO2.) |
| Secondary | Comparison of SpO₂ Temporal Parameters Between Finger and Ear Sensors | From enrollment to the end of the inclusion, estimated at approximately 10 months from the start of enrollment | Saturation sensors will be placed on the ears and fingers of healthy volunteers. Saturation parameters will be recorded from both sensors and compared with the SpO2 saturation level (baseline SpO2): * Time (in seconds) between the onset of apnea and a decrease of ≥ 2% from baseline SpO2 * Time (in seconds) between the onset of apnea and the lowest SpO2 observed before the start of resaturation * Variable describing whether the SpO2 nadir (the lowest value) occurs before or after the resumption of ventilation |
| Secondary | Quantification of SpO₂ Measurement Delay Between Measurement Sites | From enrollment to the end of the inclusion, estimated at approximately 10 months from the start of enrollment | To quantify the magnitude of the SpO₂ measurement delay (in seconds) between the two measurement sites during the reoxygenation phase. |
| Secondary | Assessment of Intra-Individual Measurement Variability | From enrollment to the end of the inclusion, estimated at approximately 10 months from the start of enrollment | To assess intra-individual variability in key measurements (focus on the delay in seconds between physiological reoxygenation and displayed SpO2) across repeated apnea tests (2 different apnea) |
| Secondary | Evolution of the Perfusion Index (PI) during Apnea and Reoxygenation by finger/auricular pulse oximeter | From enrollment to the end of the inclusion, estimated at approximately 10 months from the start of enrollment | To describe changes in the perfusion index (PI in %) during apnea and reoxygenation. Baseline PI (%) will be recorded at finger and auricular sites in healthy volunteers over time in seconds. Minimum PI during apnea, magnitude of PI change during apnea, PI recovery time (in seconds) after rebreathing. |
| Secondary | Physiological Factors Associated with SpO₂ Response Delay | From enrollment to the end of the inclusion, estimated at approximately 10 months from the start of enrollment | To explore physiological factors associated with delayed SpO₂ response (in seconds), including individual characteristics and baseline hemodynamic parameters (BMI in kg/m\^2, medical history, chronic treatments). |
