ECG AND SP O

Ensuring Accurate SpO
2
Monitoring
Each sensor requires site-specific application procedures. The quality of the patient’s pulse oximetry
measurements and pulse signals may be adversely affected by certain environmental factors, by
oximetry sensor application errors, and by patient conditions. Any of these factors can interfere with
the monitor’s ability to detect and show measurements and may result in a loss-of-pulse condition.
If the SpO
2
measurement does not seem reasonable, first check the patient’s vital signs by alternate
means and then check the pulse oximeter for proper operation.
Patients with anemia and/or significant concentrations of dysfunctional hemoglobins (such as
carboxyhemoglobin, methemoglobin, and sulphemoglobin) may appear to have normal saturation
values while actually being hypoxic. Further assessment, using means other than pulse oximetry, is
recommended for such patients.
• For anemic patients, this condition occurs because patients have decreased arterial oxygen
contents.
• For patients with dysfunctional hemoglobins (that are unable to carry oxygen), this condition
occurs because less functional hemoglobin is available to carry oxygen.
Caution:
Hemoglobin levels below 5 g/dl may prevent the monitor from providing SpO
2
values.
Other patient conditions that may result in inaccurate measurements or a loss-of-signal
condition during operation include:
• Low perfusion
• Dark pigment
• Prolonged and/or excessive patient movement
• An arterial occlusion (blocked artery) proximal to the sensor
• Venous pulsations
• Wrapping the sensor too tightly around the patient’s digit or other extremity
• Placing the sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line
• Inflating a blood pressure cuff on the limb to which the sensor is attached
External factors that may adversely affect the accuracy of oximetry readings include:
• High ambient lighting
• High-frequency electrical noise, such as electrosurgical units and defibrillators
• The presence of intravascular dyes, such as indocyanine green or methylene blue, or externally
applied coloring, such as nail polish or pigmented creams
• The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
• The patient is in cardiac arrest or is in shock
