Pulse Oximeter Hypoxia
A study testing MyHomeDoc in people with Oximetry, run by MyHomeDoc Ltd. at 1 site in United States.
Trial summary
The aim of this project is to test the accuracy of pulse oximeters (devices intended to measure oxygen saturation in blood noninvasively) during mild, moderate and severe hypoxia (a lower-than-normal concentration of oxygen in arterial blood); ie, a range of arterial HbO2 saturations from 100 to down to 70%.

About this study
Official title: Accuracy of Pulse Oximeters With Profound Hypoxia
The aim of this project is to test the accuracy of pulse oximeters (devices intended to measure oxygen saturation in blood noninvasively) during mild, moderate and severe hypoxia (a lower-than-normal concentration of oxygen in arterial blood); ie, a range of arterial HbO2 saturations from 100 to down to 70%. This is done by comparing the reading of the pulse oximeter during brief, steady state hypoxia with a gold-standard measurement of blood oxyhemoglobin (hemoglobin carrying oxygen) saturation, that is arterial blood sample processed in a laboratory.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MyHomeDocDevice
MyHomeDoc device SpO2 measurements and parallel blood gas analysis to determine oxyhemoglobin saturation (SaO2) using an ABL-90 multi-wavelength oximeter.
| Study group | Role | What they receive |
|---|---|---|
| MyHomeDoc | Experimental | Comparison of MyHomeDoc pulse oximetry readings with arterial blood saturation laboratory analysis in the same subject Receives: Device: MyHomeDoc |
What is being measured
The primary outcome is the main question the study is designed to answer.
Saturation level measurement
Induction of hypoxia by having subjects breathe mixtures of nitrogen, room air, and carbon dioxide to allow measurement of oxyhemoglobin saturation between 70-100%. Each plateau level of oxyhemoglobin saturation was maintained for at least 30 seconds or until reference pulse oximeters readings were stable
Measured: 1 hour

The record says: finished, as of the sponsor's last update on 24 Sep 2020. 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?
Saturation level measurement (time frame: 1 hour). 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 24 Sep 2020.
