SpO
2
Complies with EN ISO 9919:2005 (except alarm system; alarm system complies with IEC 60601-2-
49:2001).
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 NBP INOP suppression on: 60 seconds.
