Attention For Operation; Clinical Restrictions - PULOX PO-900 Instrucciones Para El Usuario

6.2 Attention for Operation

A. Check the device before use, and confirm that it can work
normally.
B. The finger should be in a proper position (see the attached
illustration of Figure 4 for reference), or else it may result in
inaccurate measure.
C. The ray between luminescent tube and photoelectric receiving
tube must get across subject's arteriole.
D. The device should not be used at a location or limb tied with
arterial canal or blood pressure cuff or receiving intravenous
injection.
E. Ensure that nothing, such as a plaster, can impede the light
passage, or else it may result in inaccurate measure of SpO2,
pulse rate and PI.
F. Excessive ambient light may affect the measure result. It includes
fluorescent lamp, dual ruby light, infrared heater, direct sunlight
and etc.
G. Exquisite action of the subject or extreme electrosurgical
interference may also affect the accuracy.
H. Testee can not use enamel or other makeup.
I. Please clean and disinfect the device after operating according to
the User Manual (7.1).

6.3 Clinical Restrictions

A. As the measure is taken on the basis of arteriole pulse, substantial
pulsating blood flow of subject is required. For a subject with
weak pulse due to shock, low ambient/body temperature, major
bleeding, or use of vascular contracting drug, the SpO2 waveform
(PLETH) will decrease. In this case, the measure will be more
sensitive to interference.
B. 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
SpO2 determination by this device may be inaccurate.
C. The drugs like dopamine, procaine, prilocaine, lidocaine and
butacaine may also be a major factor resulted in serious error of
SpO2 measure.
D. As the SpO2 value serves as a reference value for judgment of
anemic anoxia and toxic anoxia, some patients with serious
anemia may also report good SpO2 measure.
