Primary Outcome Measures

Name	Time	Method
Estimated venous oxygen saturation	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)
