The pulse oximeter is instandby (and displays stby in the parameter window) when• No SpO 2 sensor is connected• The sensor is off the patient during start up• You place the pulse oximeter in standbyNote: You can place the pulse oximeter in standby only when the probe is disconnected fromthe patient. A valid signal automatically brings the pulse oximeter out of standby.
