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

saturation

pulse rate

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.
