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)
