About this study

Official title: Controlled Acute Hypoxia Study Comparing Pulse Oximetry to Arterial Blood Samples Using the Abbreviated Sensor Line in Healthy Subjects With the USB Pulse Oximetry Monitor Interface Cable

The primary objective of the study is to validate the proposed claims for the OxiCable device, for pulse rate and saturation accuracy in a diverse subject population over a specified saturation range.

Read the detailed description

The general procedure of invasive controlled hypoxia clinical studies is to directly compare test pulse oximeter measurements to saturation measurements made by a multi-wavelength CO-oximeter taken from arterial blood samples from healthy human subjects. Following arterial cannulation, hypoxia is induced by reducing the percent of inspired oxygen the subject breathes while simultaneous measurements are recorded from the test pulse oximeters and arterial blood samples at targeted levels of saturation.

What participants receive

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

Study groups in NCT02216344
Study groupRoleWhat they receive
Pulse Oximeter (the device)The pulse oximetry devices were placed on subjects per the protocol. The subjects underwent gradual hypoxia and the output of the devices under test was compared to the SaO2 value as measured by a CO-Oximeter (the reference value), as outlined by ISO 80601, to ensure that the devices meet the specified performance claims.

What is being measured

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

  1. Pulse oximetry measurements of saturation from the test device will be compared to CO-Oximetry measurements of arterial oxygen saturation to demonstrate that the test sensor meets the oxygen saturation accuracy specifications for SpO2.

    Measured: up to 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Healthy and Hypoxia, run by Medtronic - MITG 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 7 inclusion and 24 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: finished, as of the sponsor's last update on 30 Sep 2016. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pulse oximetry measurements of saturation from the test device will be compared to CO-Oximetry measurements of arterial oxygen saturation to demonstrate that the test sensor meets the oxygen saturation accuracy specifications for SpO2. (time frame: up to 6 months). 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 30 Sep 2016; AzTrials last refreshed its copy on 27 Oct 2026.
