SpO
2 and pulse rate monitoring with Nellcor and M300
SpO2 precautions
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.
In the event that the SpO2 sensor becomes disconnected, a ’sensor unplugged’ alarm is annunciated. The
user may acknowledge the alarm condition to clear the alarm.
NOTE
You can configure the alarm priority for the SpO2 sensor off alarm condition. Available volume settings
are Low (default), Medium, and High.
See "Alarm priorities" on page 117 for additional information.
WARNING
When the M300 is configured for Nellcor sensors, use only Nellcor- and Dräger-specified
sensors. Other sensors may not provide adequate protection against defibrillation and may put
the patient at risk.
WARNING
A pulse 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.
CAUTION
Do not immerse the sensor or patient cable in any liquid. Moisture may present a safety risk.
NOTE
A pulse oximeter can be used during defibrillation, but the readings may be inaccurate for up to
20 seconds.
NOTE
Purchase of the M300 confers no express or implied license under any Nellcor patent to use the M300
with any oximetry sensor that is not manufactured or licensed by Nellcor.
For a list of approved sensors, see the chapter "List of accessories" on page 293.
NOTE
Do not use a functional tester to assess the accuracy of a pulse oximeter probe or a pulse oximeter mon-
itor. Since pulse oximeter measurements are statistically distributed, only about two-thirds of those mea-
surements can be expected to fall within ±A
rms of a CO-Oximeter's measured value.
