Trial summary

The goal of this study was to evaluate the accuracy of pulse oximeters over the range of 70-100% per the International Organization for Standardization (ISO) 80601-2-61:2019. Four test devices were placed on each subject on the left or right hand with two at the finger base and two at the fingertip. Read more about this study

About this study

Official title: Accuracy of the Evie Ring Pulse Oximeter in Profound Hypoxia

The goal of this study was to evaluate the accuracy of pulse oximeters over the range of 70-100% per the International Organization for Standardization (ISO) 80601-2-61:2019. Four test devices were placed on each subject on the left or right hand with two at the finger base and two at the fingertip. Motion equipment was used to control motion of the test devices. In addition, two test devices were placed on the contralateral hand on the base of a finger and also on the fingertip. Finally, a test wrist device was placed on either the left or right wrist. SpO2 measurements from these devices were compared to sampling of arterial blood during brief stable oxygen desaturation in healthy volunteers to evaluate the claimed range.

Read the detailed description

The study is an open enrollment, single-center, single blinded design using four test rings in motion compared to arterial blood gas measurements (SaO2) and to two commercially available hospital grade reference pulse oximeters (Masimo Radical-7 and Nellcor N-595) and at rest for two test rings and the test wrist device. To be included in the study, subjects had to meet all the inclusion criteria and not meet any of the exclusion criteria and to sign the written consent. Demographic data were obtained.

The investigational (7/subject) and reference devices were placed. A radial arterial cannula was placed in either the left or right wrist of each subject for arterial blood sampling and blood pressure monitoring. Each subject had two control blood samples taken at the beginning of each experiment, while breathing room air. Hands with test devices and reference pulse oximeters were maintained in motion or motionless on arm boards throughout the test. Hypoxemia was then induced to different and stable levels of oxyhemoglobin saturation (between 70-100%) by having subjects breathe mixtures of nitrogen, air, and carbon dioxide. The mixture of gases was controlled by the study physician by adjusting gas flows according to breath-by-breath estimates of oxygen saturation calculated from end-tidal partial pressure of oxygen (PO2) and partial pressure of carbon dioxide (PCO2). Each plateau level of oxyhemoglobin saturation was maintained for at least 30 seconds or until readings were stable. Two arterial blood samples were then obtained, approximately 30 seconds apart. Each stable plateau was maintained for at least 60 seconds with SpO2 fluctuating by less than 2-3%. All investigational, control, and reference data were recorded.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pulse oximeterDevice

    Devices (4) were placed on the finger base and the fingertip of two right or left fingers and placed in motion for the duration of the study. Devices (3) were placed on the contralateral side and maintained motionless for the duration of the of study. Blood samples were taken at each stable level of oxygenation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Test devices oxygen saturation accuracy

    Root Mean Squared Error (RMSE) between test devices in motion and motionless saturation of peripheral oxygen and arterial oxygen saturation.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypoxia, run by Movano Health at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 14 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Kim Tompkins (+1 (408) 981-488, ktompkins@movano.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Test devices oxygen saturation accuracy (time frame: 2 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jun 2024; AzTrials last refreshed its copy on 7 Nov 2026.
