1.Do not use the pulse oximeter together with MRI or CT equipment.
2.Explosion hazard:Do not use the pulse oximeter in an
explosive atmosphere.
3.The pulse oximeter is intended only as an adjunct in patient assessment.Doctors should make
diagnosis in conjunction with clinical manifestation and symptoms.
4.Check the pulse oximeter sensor application site frequently to make sure that the circulation
and skin integrality of patient are under good condition.
5. Do not stretch the adhesive tape while applying the pulse oximeter sensor This may cause
inaccurate reading or skin blisters.
6.Inaccurate measurements may be causes by autociaving,ethylene oxide sterlizing,or immersing
the sensors in liquid
7.Hypotension,severe vasoconstriction,severe anemia,or hypothermia may cause inaccurate reading
8.Significant levels of dysfunctional hemoglobins (such as carboxyl - hemoglobin or methemoglobin)
may cause inaccurate reading.
9.Unexpected action may cause inaccurate reading.
10.Bright nail or painted nail may cause inaccurate Sp02 reading.
