Accuracy of Methemoglobin Measurement for Rainbow DCI Sensors
A study testing DCI pulse oximeter sensor in people with Healthy, run by Masimo Corporation at 2 sites in United States.
Trial summary
In this study, the level of methemoglobin (HbMet) will be increased in a controlled manner by administering sodium nitrite intravenously in healthy volunteers. The accuracy of a noninvasive HbMet measurement by a DCI pulse oximeter sensor will be assessed by comparison to blood measurements from a laboratory analyzer. Read more about this study

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DCI pulse oximeter sensorDevice
| Study group | Role | What they receive |
|---|---|---|
| Test Group | Experimental | All subjects are enrolled into the test group and all subjects receive DCI pulse oximeter sensor. Receives: Device: DCI pulse oximeter sensor |
What is being measured
The primary outcome is the main question the study is designed to answer.
Accuracy of Sensor by Arms Calculation
Accuracy will be determined by comparing the noninvasive blood methemoglobin measurement of the pulse oximeter to that obtained from a blood sample and calculating the arithmetic root mean square (Arms) error value.
Measured: 5 hours

Questions about this trial
What is this clinical trial studying?
A study testing DCI pulse oximeter sensor in people with Healthy, run by Masimo Corporation at 2 sites 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 4 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 12 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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?
Yes. Results are posted in the registry (first posted 12 Jun 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Accuracy of Sensor by Arms Calculation (time frame: 5 hours). 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 12 Jun 2017; AzTrials last refreshed its copy on 7 Nov 2026.
