Welch Allyn 6000 Series Connex Vital Signs Monitor - User Manual - Manual (Page 153)

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 misapplied or dislodged
• severe anemia
• venous congestion
1. Verify that the sensor cable is connected to the monitor.
WARNING Patient injury risk. The sensor and extension
cable are intended only for connection to pulse co-oximetry
equipment. Do not attempt to connect these cables to a PC
or any similar device. Always follow the sensor
manufacturer's directions for care and use of the sensor.
2. Clean the application site. Remove anything, such as nail polish, that could interfere
with sensor operation.
Note Do not use disposable sensors on patients who have allergic
reactions to the adhesive.
