متن کاملBias and precision of pulse oximeters and arterial oximeters.
We evaluated measurements of oxygen saturation from four noninvasive pulse oximeters, and two conventional arterial oximeters. Simultaneous measurements were obtained on each instrument on three different occasions in five healthy subjects breathing gas with an FIO2 of 1.00, 0.50, 0.21, 0.17, 0.15, 0.13 and 0.11. Mean bias relative to the sum of oxy-, carboxy-, and methemoglobins ranged from -0...
متن کاملAccuracy and precision of fourteen pulse oximeters.
Two sets of seven pulse oximeters (Criticare CSI-502; Nellcor-N200; Datex-Satlite; Physio-Control-Lifestat 1600; Critikon-Oxyshuttle; Ohmeda-Biox 3700; Ohmeda-Biox 3740; Radiometer-Oxi; Spectramed-Pulsat; Kontron-7840; Biochem-Ox2000; Invivo-4500; Engström-EOS; Novametrix-505) were studied in two groups of eight healthy subjects, aged 26-50 yrs. The transcutaneous oxygen saturation (SpO2) was c...
متن کاملSleep desaturation: comparison of two oximeters.
Oxygen saturation is measured by pulse oximetry during sleep studies. Body movements and peripheral vasoconstriction related to respiratory events may interfere with measurements by conventional oximeters. Our objective was to compare the detection rate of sleep desaturations by two oximeters, one of which used new motion-resistant technology. We studied 34 children (median age, 13 years; range...
متن کاملDesign, simulation, and evaluation of imaging oximeters
Computer simulations have played an important role in the design and evaluation of imaging sensors with applications in remote sensing [1] and consumer photography [2-7]. In this paper, we provide an example of computer simulations used to guide the design of imaging sensors for a biomedical application: We consider how sensor design, illumination, measurement geometry, and skin type influence ...
