Overview

Brief Summary

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.

Outcomes

Primary Outcomes

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)
