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.

Ages Eligible for Study

18 years to 50 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Arterial Line
CO-Oximetry value obtained as a comparator. Obtained during motion conditions.
Device: Arterial line
Arterial line is inserted to draw a CO-Oximeter value as it is the gold standard and as advised in ISO 80601
Other Names:
  • CO-Oximeter SaO2 value
Experimental: Motion
The subject has to perform motions during the procedure. This is to verify that device is able to read through motion.
Device: Motion
The subject is asked to move their hand by either rubbing or tapping their fingers at a specified frequency and amplitude during portions of the hypoxic procedure.

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
SpO2 Accuracy During Motion Conditions - MaxA Sensor
Time Frame: up to 6 months
For each range specified, SpO2 accuracy of the pulse oximeter equipment is stated in terms of the Accuracy Root-Mean-Square (ARMS) difference between measured values (SpO2) and reference blood values (SaO2). The MaxA sensors has a different bandage from the MaxN sensor, and therefore a different form and fit.
