SpO2 and Pulse CO-Ox monitoring with Masimo SET MCable
254 Instructions for use – Infinity Acute Care System – Monitoring Applications VG6.n
SpO2 and Pulse CO-Ox precautions
SpO2 monitoring is only possible with an SpO2
MCable.
Interfering substances: Carboxyhemoglobin may
erroneously increase measurement values. The
level of increase is approximately equal to the
amount of carboxyhemoglobin present. Dyes, or
any substance containing dyes that change arterial
pigmentation, may cause erroneous measurement
values.

WARNING
High oxygen levels may predispose a
premature baby to retinopathy of prematurity.
If this is a consideration do NOT set the high
alarm limit to 100%, which is equivalent to
switching the alarm off. Transcutaneous SpO
2
monitoring is recommended for premature
babies receiving supplemental oxygen.
WARNING
An SpO2 sensor should not be used as an
apnea monitor.
WARNING
Use only Masimo-specified sensors. Other
sensors may not provide adequate protection
against defibrillation and may put the patient
at risk.
WARNING
A Pulse CO-Oximeter should be considered
an early warning device. If a trend towards
patient hypoxemia is observed, blood
samples should be analyzed by laboratory
instruments to completely understand the
condition of the patient.
WARNING
The pulsations from an intra-aortic balloon
support can elevate the pulse rate. Verify the
pulse rate of the patient against the heart rate.
WARNING
Elevated levels of methemoglobin (MetHb)
may lead to inaccurate SpO2 and SpCO
measurements.
Elevated levels of total bilirubin may lead to
inaccurate SpO2, SpMet, SpCO, SpHb, and
SpOC measurements.
Motion artifact may lead to inaccurate SpMet,
SpCO, SpHb, and SpOC measurements.
Very low arterial oxygen saturation (SaO2)
levels may cause inaccurate SpCO and SpMet
measurements.
Hemoglobin synthesis disorders may cause
erroneous SpHb readings.
WARNING
To reduce the hazard of burns during surgery,
keep the sensor or transducer and their
associated cables away from the surgical site,
the electro-surgical unit return electrode, and
earth ground.
WARNING
Inspect the application site every two to three
hours to ensure skin quality and correct
optical alignment. If the skin quality changes,
move the sensor to another site. Change the
application site at least every four hours. The
misapplication of an SpO
2 sensor with
excessive pressure for prolonged periods can
induce pressure injury.
CAUTION
Do not immerse the sensor or patient cable in any
liquid. Moisture may present a safety risk.
