1.	What gets affected by lower saturation?(a) blood flow(b) translucency(c) accuracy(d) low atmospheric pressureThis question was posed to me during an interview for a job.I'm obligated to ask this question of Electroencephalograph (EEG) topic in division Biomedical Recorders of Biomedical Instrumentation
Answer» Right choice is (c) accuracy For explanation: An accuracy of 1% or BETTER has been reported for the SATURATION range of above 80% for most TRANSMISSION type PULSE oximeters. Usually, the accuracy is less at LOWER saturation because of non-linear effects of absorption.
