Directions for use Patient monitoring 167
WARNING Inaccurate measurement risk. Use only Masimo rainbow SET
sensors and accessories on Masimo-equipped monitors.
WARNING Inaccurate measurement risk. Use only Nellcor sensors and
accessories on Nellcor-equipped monitors.
WARNING High-intensity lights (including pulsating strobe lights) directed
on the pulse co-oximeter can prevent it from obtaining readings.
WARNING The pulsations from intra-aortic balloon support can increase
the pulse rate displayed on the monitor. Verify the patient's pulse rate
against the ECG heart rate.
WARNING Inaccurate measurement risk. Venous congestion might cause
a low reading of arterial oxygen saturation. Place the sensor on a hand at
heart level to ensure proper venous outflow from a monitored site.
WARNING Inaccurate measurement risk. The pulse co-oximeter can be
used during defibrillation, but the reading may be inaccurate for up to 20
seconds.
WARNING Patient injury risk. Do not attempt to reprocess, recondition, or
modify any sensors or patient cables. Doing so might damage electrical
components.
WARNING Pulse rate measurement might not detect certain arrhythmias
because it is based on the optical detection of a peripheral flow pulse. Do
not use the pulse oximeter as a replacement or substitute for ECG-based
arrhythmia analysis.
WARNING Use the pulse co-oximeter as an early warning device. As you
observe a trend toward patient hypoxemia, use laboratory instruments to
analyze blood samples to better understand the patient's condition.
WARNING Patient injury risk. If the sensor is applied with excessive
pressure for prolonged periods, a pressure injury can occur.
WARNING Functional testers cannot be used to assess the accuracy of a
pulse oximeter monitor.
