Clinical Trial Summary

In this clinical study, the investigators will compare vital parameters measurements obtained using continuous data from reference monitors and continuous wireless MultiSense® monitoring patch in 30 healthy volunteers under induced and controlled hypoxia.


Description:

The MultiSense® strip is a unique, band aid-sized, clinical signal quality, connected strip for real-time monitoring of cardio-respiratory parameters. The MultiSense® strip measures in real-time, remotely and continuously 11 clinical key-indicators by being attached to the patient thorax: ECG trace, heart rate, oxygen saturation, respiratory rate and relative respiration depth, pulse transit time, plethysmographic trace, perfusion index, skin temperature, physical activity and body position. Designed to be worn continuously for at least seven days, the patient can keep the patch during his sleep or in the shower. The aim of this study is to determine the quality of measurements of arterial blood saturation (SpO2) provided by the MultiSense® system in comparison to measurements made with a reference Pulse Oximetry System under induced hypoxia, in terms of accuracy. The study population includes 30 healthy volunteers.

Outcome

Type Measure Description Time frame Safety issue
Primary Determination of the quality of measurements of arterial blood saturation (SpO2) provided by the MultiSense® system in comparison to measurements made with a reference Pulse Oximetry System, in terms of accuracy. Accuracy is defined as an average measurement variation less than 3.5% of the mean value to the reference standard. The data for analysis will be equally distributed across the SpO2 range of 70-100%. from patch placement to patch removal, assessed up to 3 hours
Secondary Descriptive kinetic of circulating oxidative stress markers under hypoxia conditions comparison of circulating oxidative stress and plasma antioxidant activity markers in blood between hypoxia and normal oxygenation conditions by dosage of anion superoxide (µmol/min) from patch placement to patch removal, assessed up to 3 hours
Secondary Descriptive kinetic of circulating oxidative stress markers under hypoxia conditions comparison of circulating oxidative stress and plasma antioxidant activity markers in blood between hypoxia and normal oxygenation conditions by dosage of lipids peroxidation (µg/mL) from patch placement to patch removal, assessed up to 3 hours
Secondary Descriptive kinetic of circulating oxidative stress markers under hypoxia conditions comparison of circulating oxidative stress and plasma antioxidant activity markers in blood between hypoxia and normal oxygenation conditions by dosage of protein carbonylation (ng/mL) from patch placement to patch removal, assessed up to 3 hours
Secondary Descriptive kinetic of circulating oxidative stress markers under hypoxia conditions comparison of circulating oxidative stress and plasma antioxidant activity markers in blood between hypoxia and normal oxygenation conditions by dosage of catalase (U/mg protein) from patch placement to patch removal, assessed up to 3 hours
Secondary Descriptive kinetic of circulating oxidative stress markers under hypoxia conditions comparison of circulating oxidative stress and plasma antioxidant activity markers in blood between hypoxia and normal oxygenation conditions by dosage of superoxide dismutase (U/mg protein) from patch placement to patch removal, assessed up to 3 hours
Secondary Descriptive kinetic of circulating oxidative stress markers under hypoxia conditions comparison of circulating oxidative stress and plasma antioxidant activity markers in blood between hypoxia and normal oxygenation conditions by dosage of glutathione (µmol/g protein) from patch placement to patch removal, assessed up to 3 hours
Secondary Comparison of Mitochondrial respiration from PBMCs between hypoxia and normal oxygenation conditions. Mitochondrial respiration from PBMCs is assessed by high-resolution respirometry by analysis of the kinetic of the respirometry results and comparison between each hypoxia /post-hypoxia data point with the baseline. from patch placement to patch removal, assessed up to 3 hours
Secondary To evaluate the impact of skin pigmentation on SpO2 determination by the MultiSense® solution. Comparison of the MultiSense® SpO2 performances with the reference between light and dark-pigmented subjects. Qualitative comparison of the raw PPG signal between light and dark-pigmented skin subjects. from patch placement to patch removal, assessed up to 3 hours
Secondary To evaluate pulse transit time (PTT) as an indicator of blood pressure (BP) variation. Comparison of blood pressure variation measured by a standard cuff device with PTT variation measured by the MultiSense® acquisition system. from patch placement to patch removal, assessed up to 3 hours
Secondary To evaluate the reliability of the respiration rate determined by the MultiSense® solution Determination of the quality of respiration rate provided by the MultiSense® patch in comparison to measurements made with reference medical devices in the hospital setting, in terms of accuracy. Accuracy is defined as an average measurement variation less than 5% of the respiration rate mean value to the reference standard. from patch placement to patch removal, assessed up to 3 hours
Secondary To compare the quality of MultiSense® data from a patch worn on the chest and from a patch worn on the upper back in different body posture and to evaluate the impact of strip exact localization on the chest. Qualitative comparison of the raw PPG signal between the two patches location for each subject (chest and back). Comparison of the SpO2 derived by each MultiSense® patch to the reference during the resting period in different lying positions (supine, prone, left and right side). from patch placement to patch removal, assessed up to 3 hours
