Complies with ISO 80601-2-61:2011 / EN 80601-2-61:2011.
Measurement Validation: The SpO
blood sample reference measured with a CO-oximeter. Pulse oximeter measurements are statistically
distributed, only about two-thirds of the measurements can be expected to fall within the specified
accuracy compared to CO-oximeter measurements.
Display Update Period: Typical: 2 seconds, maximum: 30 seconds. Maximum with noninvasive blood
pressure INOP suppression on: 60 seconds.
