Validation of a Miniature SpO2 Sensor in Healthy Subjects and Patients With Long-term Oxygen Therapy. (OxyFrame)

October 26, 2016 updated by: University Hospital Inselspital, Berne

Validation of a Miniature SpO2 Sensor in Healthy Subjects and Patients With Long-term Oxygen Therapy. A Prospective, Method Comparison, Proof of Concept Study.

By integrating a miniaturized pulse oximetry sensor into the frame of oxygen delivery glasses which dissimulates the nasal cannula, the investigators hope to optimize and long term oxygen therapy (LTOT) regarding medical and social aspects. The validation of the novel SpO2 sensor is the first step in the concept of personalized, dynamic delivery of oxygen by eyeglasses using a closed-loop system.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Objectives:

  1. To determine accuracy of SpO2 measurements by the novel sensor compared to 2 reference pulse oximeters in healthy subjects undergoing a normobaric hypoxic challenge provoking SpO2 desaturation.
  2. To determine accuracy of SpO2 measurements by the novel sensor compared to 2 reference pulse oximeters and to arterial blood gas analysis in patients qualifying for LTOT, breathing room air at rest (lying, sitting, standing position) and during exercise (slow walking, 6-MWT, ergometer cycle).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Assessment of accuracy in patients
Time Frame: At baseline
Assessment of the accuracy of the novel pulse oximeter sensor in patients qualifying for LTOT over the entire saturation range by calculating accuracy root mean square (ARMS). Continuous SpO2 measurement of the novel pulse oximeter will be compared to measurements assessed by 2 standard pulse oximeters and arterial blood gas analysis.
At baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assessment of accuracy in healthy volunteers
Time Frame: At baseline
Assessment of accuracy of the novel pulse oximeter sensor in healthy subjects undergoing a normobaric hypoxic challenge provoking SpO2 desaturation. SpO2 will be measured continuously over the hole procedure and SpO2 range by the novel pulse oximeter sensor and the 2 reference pulse oximeters.
