Desaturation Test With Masimo SET vs. Nellcor N-3000 (Oxismart) and N-200:

Test Protocol: Right hand is "test"; undergoing motion Left hand is "control"; held still through test sequence Saturation and pulse rate data recorded during indicated motions. Arterial desaturations to approximately 80% induced via breathing reduced FiO2 levels.
