Claim:
1. An active-pulse blood analysis system comprising: an optical sensor that illuminates a tissue site with multiple wavelengths of optical radiation and that outputs sensor signals responsive to the optical radiation after attenuation by pulsatile blood flow within the tissue site; a monitor that communicates with the sensor signals and is responsive to arterial pulses within a first bandwidth and active pulses within a second bandwidth so as to generate an arterial pulse ratio and an active pulse ratio according to the wavelengths; one or more memory devices storing an arterial calibration curve that relates arterial pulse ratios to arterial oxygen saturation values (SpO one or more memory devices storing an active pulse calibration curve that relates active pulse ratios to arterial oxygen saturation values (SpO one or more processors configured to: a selection module that outputs a third arterial oxygen saturation value (SpO
