, General
• SpO
2
style pulse oximeter measurements may be affected by numerous factors such as
bright lights, improperly applied probes, use of non-ZOLL approved sensors, patient
conditions/movements. The clinician should use good clinical judgment when
interpreting SpO
2
measurements. Should the clinician question an SpO
2
measurement, an arterial blood gas oxygen saturation measurement should be
obtained.
• Interfering substances: Carboxyhemoglobin and methemoglobin can erroneously alter
SpO
2
readings. The level of change is approximately equal to the amount of
carboxyhemoglobin or methemoglobin present. Dyes or any substance containing dyes
that alter arterial pigmentation might cause erroneous readings.
• Do not use the Propaq M pulse oximeter or oximeter sensors during magnetic
resonance imaging (MRI). Induced current could cause burns. The pulse oximeter
might affect the MRI image and the MRI unit might interfere with the accuracy of
oximetry measurements.
• Carefully arrange patient cabling to reduce the possibility of patient entanglement or
strangulation.
• Inaccurate measurements may be caused by venous pulsations.
• The pulse oximeter can be used during defibrillation, but the readings may be
inaccurate for a short time.

, Oximeter Sensor
• Use only ZOLL-approved Nellcor oximeter sensors. Other manufacturers’ sensors
might not perform properly with the Propaq M oximeter.
• Tissue damage can result from incorrect application or use of a sensor (for example,
wrapping the sensor too tightly, applying supplemental tape, failing to periodically
inspect the sensor site). To ensure skin integrity, correct positioning, and sensor
adhesion, inspect the sensor site as directed in the Directions for Use provided with the
sensor.
• Do not use damaged sensors or cables.
• Do not use a sensor with exposed optical components.
• Do not sterilize a sensor by irradiation, steam, or ethylene oxide. Refer to the cleaning
instructions in the Directions for Use for reusable Nellcor sensors.
• Do not allow the sensor to remain on the same site for a prolonged period, especially
when monitoring neonates. Check the application site at regular intervals (at least
every 2 hours) and change the site if any compromise in skin quality occurs.
• Do not attach the oximeter sensor to a limb being monitored with a pressure cuff or
with restricted blood flow.
• A poorly applied sensor might give incorrect saturation readings. A weak pulse signal
on the display might indicate a poorly applied sensor or a poorly chosen monitoring
site.
• Choose a site with sufficient perfusion to ensure accurate oximetry values.
• Certain nail aberrations, nail polish, fungus, and so on might cause inaccurate
oximetry readings. Remove any nail polish or move the sensor to an unaffected digit.
• Exposure to high ambient light from surgical lamps (especially those with a xenon light
source), bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight
can affect the accuracy of oximetry readings. To prevent interference from ambient
light, ensure that the sensor is properly applied. If necessary, cover the sensor with
opaque material.
