Nellcor
SpO2 complies with EN ISO 9919:2005.
Characteristic Specification
a
a. When performing SpO2 monitoring, the monitor SpO2 channel may not (in rare instances) initially detect a damaged SpO2 sensor or
extension cable (as described in EN ISO9919:2005, Section 51.102), but may simply display a flat line and no numerics. If this occurs,
try connecting a new SpO2 sensor (and extension cable, if needed) and restart the monitor to resume normal monitoring.
