SpO and Pulse CO-Ox monitoring with Masimo SET MCable

Overview of SpO
SpO and Pulse CO-Ox monitoring is only possible
2
with the corresponding SpO
ing hardware is available for monitoring SpO
Pulse CO-Ox parameters:
– Infinity MCable – Masimo SET
– Infinity MCable – Masimo rainbow SET
The values and the waveform are displayed on the
M540 and on the Cockpit if the M540 is docked in
an IACS configuration.
The Masimo SET MCable and Infinity MCable –
Masimo rainbow SET support motion tolerant pulse
oximetry using Signal Extraction Technology (SET).
This technology enhances the quality of SpO
itoring and also measures the percentage of func-
tional hemoglobin saturated with oxygen (SpO
the arterial blood of the patient accurately and ef-
fectively.
A sensor applied to the patient measures the ab-
sorption levels of red and infrared light. The Masi-
mo SET MCable or Masimo rainbow SET MCable
uses the difference between the two measure-
ments to calculate the percentage of saturated he-
moglobin (SpO ). Because light absorption varies
2
with blood volume and blood volume varies with
pulse rate, both types of Masimo SET MCable can
also derive a pulse rate (PLS).
In addition, the Masimo SET MCable also provides
a perfusion index (PI) value. PI is the ratio of the
pulsatile blood flow to the non-pulsatile blood flow
in peripheral tissue. The PI value provides informa-
tion regarding the perfusion status of the selected
application site. This provides a means to select the
most optimal site.
The Infinity MCable – Masimo rainbow SET mea-
sures additional parameters that continuously and
non-invasively measure blood constituents.
SpO2 and Pulse CO-Ox measurements are for
adult, pediatric, and neonatal patients (with the fol-
lowing exceptions).
