Clinical Trial 4841

Boulder, CO 80301


Study Summary:

The general purpose of Non-Invasive Controlled Acute Hypoxia Studies is to evaluate the feasibility, accuracy or performance of various non-invasive optical devices over a clinically relevant range of arterial saturations. This is achieved by controlling the percent of inspired oxygen delivered to the test subject to generate target saturations between 70 to 100%. During periods of controlled normoxia or hypoxia, data are collected continuously from test devices by a validated computer data acquisition system for direct comparison to reference standard devices (i.e., devices previously validated by direct comparison to blood measurements).


Qualified Participants Must:

• Be 18 to 50 years of age (inclusive)
• Undergo a physical examination by a licensed physician, including a 12 lead ECG and a medical history


Qualified Participants May Receive:

Subjects will incur no cost other than transportation to the Covidien facility. Subjects will be compensated if they attempt the test or are excluded by the attending clinician. All subjects will be informed that they may withdraw from the study at any time without affecting their reimbursement.

Subjects participating in the following tests are paid $75:
• Non-Invasive Pulse Oximetry Evaluation with Controlled Hypoxia.
• Non-Invasive Pulse Oximetry Evaluation with Controlled Hypoxia and Signal Interference.
Subjects participating in the following tests are paid $100:
• Non-Invasive Pulse Oximetry Evaluation with Controlled Hypoxia in Cold Room Conditions.
• Non-Invasive Pulse Oximetry Evaluation with Controlled Hypoxia in Cold Room Conditions with Signal Interference


Clinical trials are medical research studies designed to test the safety and/or effectiveness of new investigational drugs, devices, or treatments in humans. These studies are conducted worldwide for a range of conditions and illnesses. Learn more about clinical research and participating in a study at About Clinical Trials.
