Operating the Oximeter

Operator’s Manual
Note:
The type of data recorded is only displayed when data are present in the OxiMax pulse
oximetry sensor.
The oximeter displays zeros in the %SpO
2
and Pulse Rate displays while searching for
a valid pulse. For optimal performance, allow the oximeter to search and lock onto a
pulse for approximately five to ten seconds.
When a valid pulse is detected, the oximeter enters monitoring mode and displays
patient parameters using one of the available displays: general care format (factory
default display view), waveform, blip bar, or real-time trend view. The SatSeconds
icon appears in each display screen when enabled. If the SPD feature is enabled, both
the SatSeconds and SPD icons appear in each display. See
Oximeter Display View
Options , page 17.
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 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 18. 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.
Managing the Oximeter Backlight
Adjust the brightness, contrast, and backlight of the oximeter screen to suit each
individual situation.
