Fig. 5From: Continuous noninvasive hemoglobin monitoring estimates timing for detecting anemia better than clinicians: a randomized controlled trialApplication of SpHb monitoring in our study. A diagram showing the trends in SpHb (generated by the Pulse CO-Oximetry) and intermittent CoOxHb measurements taken in one patient in our study. Red blood drops represent invasive CoOxHb measurements. The blue wavy line represents the continuous monitoring of SpHb during surgeryBack to article page
