is converted into electrical signals by the photo-detector in the probe. The SpO
2
module processes the elec-
trical signals and gives out waveform data and digital values for SpO
2
and pulse rate displayed on the screen.
10.2 Safety Information
Continuous use of fingertip SpO
2
sensor may result in discomfort or pain, especially for those patients 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 meas-
uring site periodically if necessary.
Check SpO
2
probe application site periodically (every 30 minutes) to determine circulation, positioning and
skin sensitivity.
SpO
2
measuring site must be examined more carefully for some special patient. Do NOT place the SpO
2
sensor on the finger with edema or fragile tissue.
Avoid placing the SpO
2
sensor on the same extremity with an arterial catheter, blood pressure cuff, or intra-
vascular infusion line, otherwise the blood flow could be interrupted by the cuff or the circulatory condition
could make low blood perfusion so that would result in no pulse found or loss of pulse during SpO
2
moni-
toring and further cause false alarm.
The SpO
2
measurement of this monitor may not work effectively for all kinds of patients, for whose with
weak pulse due to shock, low ambient/body temperature, major bleeding, or use of vascular contracting
drug, the measurement will be more sensitive to interference, if stable readings cannot be obtained at any
time, discontinue use of SpO
2
monitoring function.
For those with a substantial amount of staining dilution 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
determination 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 affect the measuring result, it includes fluorescent lamp, dual ruby light, infra-
red heater, and direct sunlight etc.
As the SpO
2
value serves as a reference value for judgment of anemic anoxia and toxic anoxia, the meas-
urement result of some patients 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 pulsation may lead to inaccurate
oxygen saturation measurements.
Vigorous movement of the patient, strong ambient light, or extreme electro-surgical interference may also
affect the SpO
2
measuring accuracy.
DO NOT stare at the light of SpO
2
sensor (infrared is invisible) when switch it on, for the infrared may do
harm to the eye.
The information, such as the range of the peak wavelengths and maximum optical output power of the light
by the SpO
2
sensor can be especially useful to clinicians.
Always observe the plethysmogram (waveform), which is auto-scaled (normalized). When the measured
signal is inadequate, the waveform will be not smooth or irregular, the SpO
2
reading may be unlikely true
or displayed with “--”, and even a technical alarm will be generated. If in doubt, rely on your clinical judge-
ment, rather than the monitor readout.
Please do not use the SpO
2
sensor and the monitor when doing the MRI imaging, or burn may be caused
by faradism.
For disposal SpO
2
sensor, if the sterile packaging is damaged, do not use it any more.
Check the SpO
2
sensor and cable before use. Do NOT use the damaged SpO
2
sensor.
Before each use, surface-clean sensor and cable with a soft gauze pad by saturating it with a solution such
as 70% isopropyl Ethanol. If low-level disinfection is required, use a 1:10 bleach solution.
When the temperature of SpO
2
sensor is abnormal, do not use it any more.
Please do not allow the cable to be twisted or bent.
Please do not use nail polisher or other cosmetic product on the nail.
The fingernail should be of normal length.
The SpO
2
sensor cannot be immersed into water, liquor or cleanser completely, because the sensor has no
capability to resist the harmful ingress liquid.
Do not disinfect any SpO
2
sensor by irradiation, steaming, or ethylene oxide.
Carefully route cables to reduce the possibility of patient entanglement or strangulation.
The clinical study for SpO
2
measurement accuracy was done on human subjects according to Standard
ISO 80601-2-61.
A functional tester or SpO
2
simulator cannot be used to assess the accuracy of the oximeter or a SpO
2
sensor. However, it can be used to check how accurately a particular oximeter is reproducing the given
calibration curve. Before testing the oximeter by a functional tester, please firstly ask the manufacturer
