Study inclusion criteria were as follows: therapeutic medical requirement for measurement of arterial oxygen saturation, age 18 or older, physiologic stability (<10% variation in HR, blood pressure, respiratory rate, temperature, and noninvasive oxygen saturation within the past 15 minutes), lack of physical impediments to proper use of the noninvasive pulse oximeter devices, no ventilator setting changes or changes in inspired oxygen concentration in nonventilator dependent patients 10 minutes prior to data collection, and/or absence of a medical diagnosis of peripheral vascular disease or tetralogy of Fallot.

Under the guarantee, if Masimo SET is proven not to be superior to all Nellcor pulse oximeters, including the three that Covidien announced have received FDA 510(k) clearance with motion claims, Masimo will pay up to USD 1m to help a hospital acquire that pulse oximetry.
Cardiac arrhythmias also may prevent a true reading of the pulsatile signal (Hill & Stoneham, 2000), and accurate pulse oximeter readings may not be obtained during severe or rapid oxygen desaturation (DeMeulenaere, 2007; Jensen, Onyskiw, & Prasad, 1998).
