VALIDATION OF REFLECTANCE PULSE OXIMETRY: AN EVALUATION OF A NEW SENSOR IN PIGLETS

K, Mannheimer P. Validation of reflectance pulse oximetry: an evalua tion o f a new sensor in piglets. j Clin Monit 1997; 13: 43-49 ABSTRACT, Objective. A new reflectance pulse oximetry sen sor, developed for intrapartum estimation of arterial oxygen saturation (SaCy, was calibrated and evaluated. The sensor contains two light emitting diodes of 735 and 890 nm, and a photo detector at a distance of 14 mm from both light emit ting diodes. Methods. In seven Yorkshire/Hampshire piglets, the reflectance sensor (Nellcor Puritan Bennett Inc.) was cali brated using blood sample SaC>2 values. The resulting calibra tion line was evaluated in four Dutch piglets, by comparing pulse oximetry saturation readings (SpC>2) with blood sample and intravascular fiberoptic oximetry SaC>2 values. Several reflectance sensors were fixed on each animal. Desaturatio
