Low Spo Measuring Value Caused By Pathology Reason; Clinical Limitations; Points To Be Noted In Spo And Pulse Measuring - Gima 35132 Manual De Uso

There is an arterial occlusion proximal to the sensor
²
Blood vessel contraction caused by peripheral vessel hyperkinesias or body temperature decreasing
²
8.2.3 Low SpO measuring value caused by pathology reason
2
Hypoxemia disease, functional lack of HbO
²
Pigmentation or abnormal oxyhemoglobin level
²
Abnormal oxyhemoglobin variation
²
Methemoglobin disease
²
Sulfhemoglobinemia or arterial occlusion exists near sensor
²
Obvious venous pulsations
²
Peripheral arterial pulsation becomes weak
²
Peripheral blood supply is not enough
²

8.2.4 Clinical Limitations

As the measure is taken on the basis of arteriole pulse, substantial pulsating blood stream of subject is
²
required. For a subject with weak pulse due to shock, low ambient/body temperature, major bleeding,
or use of vascular contracting drug, the SpO
measurement will be more sensitive to interference.
For those with a substantial amount of staining dilution drug (such as methylene blue, indigo green
²
and acid indigo blue), or carbon monoxide hemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic
hemoglobin, and some with icterus problem, the SpO
inaccurate.
The drugs such as dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor

blamed for serious error of SpO
As the SpO

8.2.5 Points to be noted in SpO
The finger should be properly placed (see the attached illustration of this instruction manual), or else it
²
may cause inaccurate measurement result.
Make sure that capillary arterial vessel beneath the finger is penetrated through by red and infrared
²
lights.
The SpO sensor should not be used at a location or limb tied with arterial or blood pressure cuff or

receiving intravenous injection.
Do not fix the SpO

Make sure the optical path is free from any optical obstacles like adhesive tape.

Excessive ambient light may affect the measuring result. It includes fluorescent lamp, dual ruby light,
