NELLCOR® OXIMAX® SpO2: Description
Description
The SpO
2
parameter in the Dash 2500 Patient Monitor is available in two
different leading technologies: NELLCOR
®
and MASIMO SET
®
. Please refer to the
side of your Monitor to see which SpO
2
technology your Monitor contains. The
SpO
2
technology logo will be on the side of the Monitor next to the SpO
2
connector. This section refers to NELLCOR
®
SpO
2
technology.
Functional oxygen saturation (SpO
2
) of arterial blood is monitored in the Dash
2500 Patient Monitor by a pulse oximetry parameter that provides continuous,
noninvasive measurements of SpO
2
and can provide displays of pulse rate, a
plethysmographic waveform, and a pulse amplitude bar. The pulse amplitude
bar graph is proportional to the arterial blood flow. To begin SpO
2
monitoring,
plug the sensor into the SpO
2
port, place the SpO
2
sensor on the patient's finger,
and monitoring begins automatically.
Functional SpO
2
is the ratio of oxygenated hemoglobin to hemoglobin that is
capable of transporting oxygen. This ratio, expressed as a percentage, is shown
in the SpO
2
field of the screen and is updated with each heart beat. The
percentage of SpO
2
is also indicated by a pulse tone that is activated by the
Adjust QRS volume option in the HR/Pulse menu. The pitch frequency of the
tone is proportional to the oxygen saturation value: highest at 100% saturation
and lower with each percentage point as the level of saturation falls.
Pulse Rate derived from SpO
2
appears under the following conditions:
 View SpO2 PR? option is set to yes:
When pulse rate (PR) is derived from SpO
2
, the value appears in the SpO
2
vital signs field.
NOTE: Unless PR is the source for the HR/Pulse, it is only trended when the
View SpO2 PR? option is set to yes.
 View SpO2 PR? option is set to no:
PR will not appear in the SpO
2
vital signs field, but SpO
2
is still a valid source
for the HR/Pulse.
 When SpO
2
is the source for the HR/Pulse:
Pulse rate derived from SpO
2
appears only in the HR vital signs field (dashes
appear for PR in the SpO
2
vital signs field).
The SpO
2
parameter has audible and visible alarms to let you know when the
SpO
2
levels are outside the alarm limits, as well as artifact detection. If artifact is
detected, the ARTIFACT alarm appears under the SpO
2
value in the vital signs
area. If the View SpO2 PR? option is set to yes, audible and visible alarms for the
pulse rate (derived from SpO
2
) are activated. The alarm limits for PR are the
same as those for HR/Pulse.
