General Introduction
Data In-Sensor Indicator—Lights to indicate that the attached OxiMax pulse
oximetry sensor contains a patient sensor event record. The sensor event record
information may be viewed or printed.
Battery Fuel Gauge—Displays the battery charge remaining on the oximeter. The
battery fuel gauge consists of four bars, each corresponding to approximately 1.5
hours of operating time. All four bars are lit when the battery is fully charged. No bars
are lit when a low battery condition exists. Visible in all display views. See Battery Fuel
Gauge Levels, page 55.
Plethysmographic (pleth) Waveform—This non-normalized waveform uses real-
time sensor signals, reflecting relative pulsatile strength and quality of incoming
signals. This indicator is only available in the pleth display view.
Pulse Amplitude (blip bar)—Indicates pulse beat and the relative (non-normalized)
pulse amplitude. As the detected pulse becomes stronger, more bars light with each
pulse. This indicator is only available in the blip and general care format (GCF) display
views.
%SpO2 Value—Indicates hemoglobin oxygen saturation levels. The display value
flashes zeros during loss-of-pulse alarms and flashes the %SpO
SpO is outside the alarm limits. The oximeter continues to update the display during
2
Pulse Search. Current upper and lower alarm limit settings appear as smaller values
to the right of the dynamic %SpO
Pulse Rate Value—Displays the pulse rate in beats per minute. It flashes during
loss-of-pulse alarms and when the pulse rate is outside of the alarm limits. During
Pulse Search, the oximeter continues to update the display. Pulse rates outside of the
pulse rate range of 20 to 250 bpm are displayed as 0 and 250, respectively. Current
upper and lower alarm limit settings appear as smaller values to the right of the
dynamic pulse rate value. Visible in all display views.
Saturation Pattern Detection (SPD) Icon—The OxiMax SPD™ Alert (SPD) feature
detects patterns of desaturation in the SpO
enabled, the oximeter detects patterns of desaturation indicative of repetitive
reductions in airflow through a patient's upper airway into the lungs. When the SPD
feature detects patterns of desaturation in the SpO
alerted to these patterns via a visual indicator, and optionally, an audio alarm. The
triangle icon for OxiMax SPD™ Alert appears on the monitor display when the feature
is enabled. The triangle fills from the bottom to the top as patterns become more
severe. The triangle empties from top to bottom as the patterns become less severe.
If the triangle fills, an alarm sounds. With Saturation Pattern Detection enabled, the
default setting is On with the sensitivity set to 1. The feature can be turned off in the
LIMITS menu. Caregivers can select from three alarm sensitivity settings: 1 (most
sensitive), 2 (medium sensitivity) or 3 (least sensitive), with 1 resulting in more alarms
and 3 resulting in fewer alarms. The rate at which the SPD icon fills depends on the
SPD sensitivity setting. To explore activation, contact Nellcor's Technical Services
Department at 1.800.635.5267 or your local Nellcor representative. To use the
feature, reference the N-600x Operator's Manual.
