Inclusion Criteria: * Subject must have the ability to understand and provide written informed consent * Subject is 18 to 50 years of age * Subject must be willing and able to comply with study procedures and duration * Subject is a non-smoker or who has not smoked within 2 days prior to the study Exclusion Criteria: * Participant is considered as being morbidly obese (defined as BMI \>39.5) * Compromised circulation, injury, or physical malformation of fingers, wrist, hands, ears or forehead/skull or other sensor sites which would limit the ability to test sites needed for the study.
