WARNING The accuracy of SpHb 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.
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. Verify that you are using the Monitor profile.
3. 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.
4. Attach the sensor to the patient according to the manufacturer's directions for use, observing
all warnings and cautions.
Note If a sterile sensor is required, select a sensor that has been
validated for sterilization, and follow the sensor manufacturer's
directions for sterilizing the sensor.
Place the sensor and the NIBP cuff on different limbs to reduce unnecessary alarms when you
monitor these parameters at the same time.
