An interventional study of Use of impedance threshold device during spontaneous ventilation in Healthy, sponsored by University of Virginia. Completed at 1 site in United States. Open to participants aged 18 Years to 65 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2014-04-16.
Sponsored by University of Virginia · Not applicable, Interventional, and Diagnostic
The purpose of this study is to determine whether analysis of near infrared absorbance signals that occur at different frequencies might provide information about the difference in oxygen saturation between arterial and venous blood.
University of Virginia is the lead sponsor of 653 studies on the registry; 134 are open to participants now.
Of its 60 completed or terminated interventional studies of FDA-regulated products, 41 (68%) have results posted.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
All subjects will undergo spontaneous ventilation through an impedance threshold device and ScvO2 will be recorded before and after
Other: Use of impedance threshold device during spontaneous ventilation
Estimated venous oxygen saturation
Oxygen saturation will be calculated from the five minute period of time prior to use of the impedance threshold device (0-4 mins), and then again in the 2 minute period after the impedance threshold device is applied (5-6 mins)
Time frame: From 5 to 6:59 minutes after applying the impedance threshold device
