Rad-97 Safety Information, Warnings and Cautions
www.masimo.com 20 Masimo
Note: Always charge Rad-97 when it is not in use to ensure that the Rad-97 Battery Module
remains fully charged.
Note: All batteries lose capacity with age, thus the amount of run time at Low Battery will
vary depending upon the age of the Battery Module.
Note: A functional tester cannot be used to assess the accuracy of Rad-97.
Note: When monitoring acoustic respiration, Masimo recommends minimally monitoring
both oxygenation (SpO
2
) and respiration (RRa).
Note: When using the Maximum Sensitivity setting, performance of the "Sensor Off"
detection may be compromised. If the Rad-97 is in this setting and the sensor becomes
dislodged from the patient, the potential for false readings may occur due to environmental
"noise" such as light, vibration, and excessive air movement.
Noninvasive Blood Pressure
WARNING: Before applying the cuff on the patient, confirm the cuff size is appropriate.
WARNING: When a blood pressure measurement error code occurs, any blood pressure values
reported should be disregarded.
CAUTION: If the blood pressure cuff is on the same limb as monitoring equipment (i.e., pulse
oximeter probe), the pressurization within the cuff can cause temporary loss of function of the
monitoring equipment.
CAUTION: Blood pressure measurements can be affected by the patient's position,
physiological condition, and environmental factors.
Note: Physiological conditions that can affect blood pressure measurements include, but are
not limited to, cardiac arrhythmias, arterial sclerosis, poor perfusion, diabetes, age,
pregnancy, pre-eclampsia, renal diseases, trembling, and shivering.
NomoLine Capnography
WARNING: Use only airway T-adapters with the sampling point in the center of the adapter.
WARNING: Do not use T-adapter with infants, as this adds 7 ml dead space to the patient
circuit.
WARNING: Do not use the NomoLine capnography with metered-dose inhalers or nebulized
medications as this may clog the bacteria filter.
WARNING: Since a successful zeroing requires the presence of ambient air (21% O
2
and 0%
CO
2
), ensure that the Rad-97 is placed in a well ventilated place. Avoid breathing near the
NomoLine capnography sidestream gas analyzer before or during the zeroing procedure.
WARNING: The NomoLine capnography is intended only as an adjunct in patient
assessment. It must be used in conjunction with other assessments of clinical signs and
symptoms.
WARNING: Replace the sampling line if the sampling line input connector starts flashing red,
or Rad-97 displays a “Check sampling line” message.
WARNING: Too strong positive or negative pressure in the patient circuit might affect the
sample flow.
WARNING: Strong scavenging suction pressure might affect the sample flow.
