Chapter 10 Monitoring Oxygen Saturaon (SpO
2
)
10.1 Introducon
The funconal oxygen saturaon (SpO
2
) - a percentage of the hemoglobin that can transport oxygen, is monitored by this
device via a non-invasive opcal technique. Based on the principle that oxygenated hemoglobin (HbO
2
) and deoxygenated
hemoglobin (Hb) have dierent absorpon character in the spectrum range from red to infrared light, the device measures
the amount of oxygenated hemoglobin and pulse rate by measuring the absorpon of selected wavelengths of light. The
light generated in the probe passes through the ssue and is converted into electrical signals by the photo-detector in
the probe. The SpO
2
module processes the electrical signals and gives out waveform data and digital values for SpO
2
and
pulse rate displayed on the screen.
10.2 Safety Informaon
 Connuous use of ngerp SpO
2
sensor may result in discomfort or pain, especially for those paents with
microcirculatory problem. It is recommended that the sensor should NOT be applied to the same site for over
two hours, please inspect the monitoring site every 1~2 hours for skin integrity, and change the measuring site
periodically if necessary.
 Check SpO
2
probe applicaon site periodically (every 30 minutes) to determine circulaon, posioning and skin
sensivity.
 SpO
2
measuring site must be examined more carefully for some special paent. Do NOT place the SpO
2
sensor on
the nger with edema or fragile ssue.
 Avoid placing the SpO
2
sensor on the same extremity with an arterial catheter, blood pressure cu, or intravascular
infusion line, otherwise the blood ow could be interrupted by the cu or the circulatory condion could make
low blood perfusion so that would result in no pulse found or loss of pulse during SpO
2
monitoring and further
cause false alarm.
 The SpO
2
measurement of this monitor may not work eecvely for all kinds of paents, for whose with weak
pulse due to shock, low ambient/body temperature, major bleeding, or use of vascular contracng drug, the
measurement will be more sensive to interference, if stable readings cannot be obtained at any me, disconnue
use of SpO
2
monitoring funcon.
 For those with a substanal amount of staining diluon drug (such as methylene blue, indigo green and acid
indigo blue), or carbon monoxide hemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic hemoglobin, and
some with icterus problem, the SpO
2
determinaon by this monitor may be inaccurate.
 The drugs such as dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor blamed for
serious error of SpO
2
measurements.
 Excessive ambient light may aect the measuring result, it includes uorescent lamp, dual ruby light, infrared
heater, and direct sunlight etc.
 As the SpO
2
value serves as a reference value for judgment of anemic anoxia and toxic anoxia, the measurement
result of some paents with serious anemia may also present as good SpO
2
value.
 Do not apply tape to secure the sensor in place or to tape it shut; venous pulsaon may lead to inaccurate oxygen
saturaon measurements.
