Managing the Oximeter Backlight

The movement of the blip bar, the plethysmographic waveform, or the flashing heart
icon indicates real-time data display. The pulse beep tone is an audible indicator of
the real-time patient data.
Caution
If the pulse beep tone does not sound with each pulse, the pulse beep volume is set to zero,
the speaker is malfunctioning, or the signal is corrupt.
When first applying an OxiMax pulse oximetry sensor to a patient, the oximeter may
lose a pulse signal. If a pulse signal is lost, an alarm sounds and a poor signal
condition message displays on the oximeter screen. At this point, the oximeter
displays [--- / ---](three dashes over three dashes) and remains in the Pulse Search
mode for five seconds before displaying the poor signal condition screen. The poor
signal condition screen is part of the Sensor Messages feature.
Figure 21.
Poor Signal Condition Message
Sensor Detection Failure
Upon successful completion of the POST process, the oximeter sounds a one-second
tone indicating that the oximeter has passed POST.
Should the oximeter fail to detect an OxiMax pulse oximetry sensor, the oximeter
displays dashes [ - - - ] and the Pulse Search indicator does not light.
