Four Types of Pulse Oximeters Accurately Detect Hypoxia During Low Perfusion and Motion
Four Types of Pulse Oximeters Accurately Detect Hypoxia During Low Perfusion and Motion
Evaluate the performance of 4 pulse oximeters in 10 healthy adult volunteers with three motions compared to non-motion control at three arterial oxygen saturation target plateaus.
Evaluate the performance of 4 pulse oximeters (Masimo Radical-7, Nihon-Koden OxyPal Neo, Nellcor N-600, and Philips Intellivue MP5) in 10 healthy adult volunteers. Three motions will be evaluated: tapping, pseudorandom, and volunteer-generated rubbing, adjusted to produce photoplethsmogram disturbance similar to arterial pulsation amplitude. During motion, inspired gases will be adjusted to achieve stable target plateaus of arterial oxygen saturation (SaO2) at 75%, 88%, and 100%. Pulse oximeter readings (SpO2) will be compared with SaO2 from simultaneous arterial blood samples
