WARNING Inaccurate measurement risk. Use only Nellcor sensors and
accessories on Nellcor-equipped monitors.
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 Patient injury risk. Do not attempt to reprocess, recondition, or recycle
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 The accuracy of SpO2 measurements can be affected by any of the
following:
•
elevated levels of total bilirubin
• elevated levels of Methemoglobin (MetHb)
• elevated levels of Carboxyhemoglobin (COHb)
• hemoglobin synthesis disorders
• low perfusion at the monitored site
• the presence of concentrations of some intravascular dyes, sufficient to change the
patient's usual arterial pigmentation
• patient movement
• patient conditions such as shivering and smoke inhalation
• motion artifact
• painted nails
• poor oxygen perfusion
• hypotension or hypertension
• severe vasoconstriction
• shock or cardiac arrest
• venous pulsations or sudden and significant changes in pulse rate
• proximity to an MRI environment
• moisture in the sensor
• excessive ambient light, especially fluorescent
• the use of the wrong sensor
• a sensor applied too tightly
1. Verify that the sensor cable is connected to the monitor.
