flammable substances, oxygen-enriched environments, or nitrous oxide to avoid the risk of explosion.
15.Caution,When using this product, you only need to fix it on your fingers. Excessive pressure on your
fingers may cause skin damage.
16.Caution, The maximum skin surface temperature is below 41℃(106℉) when measured in a 35℃
(95℉)environment, which has been verified by measuring the skin surface temperature via a Finger
Pulse Oximeter under the reasonable worst conditions.

General Description
Oxyhemoglobin saturation is percentage of Oxyhemoglobin (O2Hb) capacity, compounded with oxygen, by
all combinativable haemoglobin (Hb) Oxyhemoglobin (O2Hb) capacity in blood. In other words, it is
consistence of Oxyhemoglobin in blood. It is a very important ecological parameter for Respiratory
Circulation System. Many respiratory diseases can result in oxyhemoglobin saturation being lowered in
human blood. Moreover, the following factors can also lead to problems in oxygen supply, so that human
oxyhemoglobin saturation might be reduced: Automatic Organic Regulation Malfunction caused by
Anesthesia, intensive Postoperative Trauma, hurts resulted in by some medical examination and etc. In the
situation, illnesses, such as dizziness, asthenia, emesis and etc, might happen to patients and even
endanger the patient's life. Therefore, it is very important to know oxyhemoglobin saturation of patient timely
in clinical medical aspects. So that doctors can find problems in time.
The YUWELL® Finger Pulse Oximeter features in small volume, low power consumption, convenient
operation and portable. It is only necessary for patient to put one of his fingers into a fingertip photoelectric
sensor for measurement, and then the screen will display the measured value of pulse oxygen saturation
and pulse rate. It has been proved in clinical experiments that it features in rather high precise and repeatability.
Measurement Principle
Principle of the Oximeter is as follows: An experience formula of data process is established taking use
of Lambert Beer law according to Spectrum Absorption Characteristics of deoxyhaemoglobin(HHb) and
Oxyhemoglobin (O2Hb ) in glow and near-infrared zones. Operation principle of the instrument is
Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse
Scanning and Recording Technology, so that two beams
of different wavelength of light (red light and infrared light)
can be focused onto human nail tip through perspective
clamp finger-type sensor. Then measured signal can be
obtained by a photosensitive element, information
acquired through which will be shown display through
process in electronic circuits and microprocessor.

The essential performance of this product is the accuracy of SpO2 and pulse rate (SpO2 Accuracy:
±2% in the range of 70%-100% of SpO2, No definition for SpO2 under 70%;Pulse rate:
25bpm~250bpm, accuracy: ±1% or ±1bpm(larger)). When used directly near strong electromag-
netic interference (for example: near mobile phones, microwave ovens, etc.), it may be temporarily
inaccurate. If so, please keep the product away from interfering devices.
The finger pulse oximeter may exhibit temporary degradation of performance (e.g.deviation from the
performance indicated in the instructions for use during IMMUNITY testing) and the finger pulse
oximeter can recover from any interference within 30 seconds without affecting basic safety or
performance without operator intervention.The following degradations, if associated with BASIC
SAFETY or ESSENTIAL PERFORMANCE shall not be allowed:
- component failures;
- changes in programmable parameters or settings;
- reset to default settings;
- change of operating.
During measurement, The use of this equipment adjacent to or stacked with other equipment should
be avoided because it could result in improper operation. If such use is necessary, this equipment
and the other equipment should be observed to verify that they are operating normally.
During measurement, portable RF communications equipment (including peripherals such as
antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part
of the finger pulse oximeter, including cables specified by the manufacturer. Otherwise, degradation
of the performance of this equipment could result.
