Radical-7 Warnings and Cautions
www.masimo.com 23 Masimo
Caution: If the Low Perfusion message is frequently displayed, find a
better perfused monitoring site. In the interim, assess the patient and, if
indicated, verify oxygenation status through other means.
Caution: If using pulse oximetry during full body irradiation, keep the
sensor out of the radiation field. If the sensor is exposed to the radiation,
the reading might be inaccurate or the device might read zero for the
duration of the active irradiation period.
Caution: Variation in hemoglobin measurements may be profound and
may be affected by sampling technique as well as the patient's
physiological conditions. Any results exhibiting inconsistency with the
patient’s clinical status should be repeated and/or supplemented with
additional test data. Blood samples should be analyzed by laboratory
instruments prior to clinical decision making to completely understand
the patient’s condition.
Caution: If SpO2 values indicate hypoxemia, a laboratory blood sample
should be taken to confirm the patient’s condition.
Caution: When using In Vivo Adjustment™, confirm offset values(s)
periodically as the difference between the displayed parameter value and
the laboratory reference value may vary over time.
Caution: Do not use In Vivo Adjustment if the monitor displays a Low
SpHb SIQ message.
Note: Use the Radical-7 in accordance with Environmental Specifications
section in this manual.
Note: If the Radical-7 stops communicating with Root, parameters and
measurements will not show on the Root display; however, this will not
affect Radical-7's ability to monitor the patient.
