Use of Near Infrared Spectroscopy to Measure Intracranial ScvO2

April 15, 2014 updated by: Robert Thiele, MD, University of Virginia
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.

All subjects will undergo spontaneous ventilation through an impedance threshold device and ScvO2 will be recorded before and after

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Estimated venous oxygen saturation
Time Frame: From 5 to 6:59 minutes after applying the impedance threshold device
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)
From 5 to 6:59 minutes after applying the impedance threshold device
