During exercise, pulse
oximetry is problematic due to motion artifact and altered digital
perfusion. New pulse oximeter technology addresses these issues and may
offer improved performance. We simultaneously compared Nellcor N-395
(Oxismart XLTM) pulse oximeters with an RS-10 forehead sensor (RS-10),
a D-25 digit sensor (D-25), and the Ivy 2000 (Masimo SETTM)/LNOP-Adt
digit sensor (Ivy) to arterial blood oxygen saturation
(Sa O 2 ) by cooximetry. Nine normal subjects, six
athletes, and four patients with chronic disease exercised to maximum
oxygen consumption ( O 2 max ) under various conditions [normoxia, hypoxia inspired oxygen fraction (F I O 2 ) = 0.125; hyperoxia,
F I O 2 = 1.0]. Regression analysis for normoxia and hypoxic data was performed ( n = 161 observations, Sa O 2 = 73-99.9%), and bias
(B) and precision (P) were calculated. RS10 offered greater validity
than the other two devices tested ( y = 1.009 x 0.52, R 2 = 0.90, B±P = 0.3 ± 2.5). Finger sensors had low precision and a
significant negative bias (D-25: y = 1.004 x 2.327, R 2 = 0.52, B±P = 2.0 ± 7.3; Ivy: y = 1.237 x 24.2, R 2 = 0.78, B±P = 2.0 ± 5.2). Eliminating measurements in which heart
rate differed by >10 beats/min from the electrocardiogram value
improved precision minimally and did not affect bias substantially (B±P = 0.5 ± 2.0, 1.8 ± 8.4, and 1.25±4.33 for
RS-10, D-25, and Ivy, respectively). Signal detection algorithms and
pulse oximeter were identical between RS-10 and D-25; thus the improved performance of the forehead sensor is likely because of sensor location. RS-10 should be considered for exercise testing in which pulse oximetry is desirable.
