1.3. Hazards

Hazards

Keep the oximeter away from dust, vibration, corrosive substances, explosive materials, high

temperature and moisture.

If the oximeter gets wet, please stop using

it

immediately .

When

it

is carried from cold environment to warm or humid environment, please do not use

it

immediately

DO NOT operate keys on front panel with sharp materials.

High temperature or high pressure steam disinfection of the oximeter is not permitted. Refer to

User Manual

in

the relative chapter (7.1) for instructions of cleaning and disinfection .

Do not have the oximeter immerged

in

liquid. When

it

needs cleaning, please wipe its surface

with medical alcohol by soft material. Do not spray any liquid on the device directly.

When cleaning the device with water, the temperature should be lower than 60 ℃ .

T he fingers which are too thin or too cold may affect the meas ure accuracy , please clip the

thick er finger such as thumb or middle finger deeply enough into the probe.

The pulse oximeter can be used to adult or infant. Whether the device is used to adult or

infant,it depends on the probe selected ( optional ) .

The update period of data is less than 5 seconds, which is changeable according to different

individual pulse rate.

Please read the measured value when the waveform on screen is equably and steady-going,

This measured value is optimal value. And the waveform at the moment is the standard one.

If some abnormal conditions appear on the screen during test process, pull out the finger and

reinsert to restore normal use.

2. Overview

Overview

The pulse oxygen saturation is the percentage of

Hb

O

2

in

the total Hb

in

the blood, so-called the O

2

concentration

in

the blood. It is an important bio-parameter for the respiration.

A

number of diseases

relating to respiratory system may cause the decrease of SpO

2

in

the blood, furthermore, some other

causes such as the malfunction of human body's self-adjustment, damages during surgery, and the

injuries caused by some medical checkup would also

lead

to the difficulty of oxygen supply

in

human body, and the corresponding symptoms would appear as a consequence, such as vertigo,

impotence, vomit etc. Serious symptoms might bring danger to human's life. Therefore, prompt

information of patients' SpO

2

is of great help for the doctor to discover the potential danger, and is of

great importance

in

the clinical medical field. The Pulse Oximeter features

in

small volume, low

power consumption, convenient operation and being portable.It is only necessary for patients to put

one of his fingers into a probe for diagnosis, and a display screen will directly show the measured

value of pulse oxygen s aturation with the high veracity and repetition.

in

sports (It can be used before or after doing sports, and

it

is not recommended to use

the device during the process of having sport ) and etc.

The problem of overrating would emerge when the patient is suffering from toxicosis which

Clinical restrictions

restrictions

A.

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 SpO

2

waveform (PLETH) will decrease. In

this case, the measurement will be more sensitive to interference.

B.

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 SpO

2

determination by this device may

be inaccurate.

C.

C. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major

factor resulted

in

serious error of SpO

measure.

D.

D. T he SpO

2

value serves as a reference value for judgment of anemic anoxia and toxic anoxia, for

some patients with serious anemia may also report good SpO

measurement.
