Oxygen Saturation is a percentage of Oxyhemoglobin (HbO2) capacity, compounded with oxygen, by all combinative hemoglobin (Hb)
capacity in blood. In other words, it is consistency of Oxyhemoglobin in blood. It is a very important parameter for the Respiratory
Circulation System. Many respiratory diseases can result in oxygen saturation being lowered in human blood. Additionally, the following
factors can reduce oxygen saturation: Automatic regulation of organ dysfunction caused by Anesthesia, Intensive Postoperative Trauma,
injuries caused by some medical examinations. That situation might result in light-headedness, asthenia, and vomiting. Therefore, it is
very important to know the oxygen saturation of a patient so that doctors can find problems in a timely manner.
The fingertip pulse oximeter features low power consumption, convenient operation and portability. Place one fingertip into the
photoelectric sensor for diagnosis and the pulse rate and oxygen saturation will appear on the display. It has been proven in clinical
experiments that it also features high precision and repeatability.
Principle of the oximeter is as follows: A mathematical formula is established making use of Lambert Beer Law according to Spectrum
Absorption Characteristics of Reductive hemoglobin (RHb) and Oxyhemoglobin (HbO2) in red and near-infrared zones. Operation
principle of the instrument: Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scanning
and Recording Technology, so that two beams of different wavelength of lights (660nm red and 905nm near infrared light) can be
focused onto a human nail tip through a clamping finger-type sensor. A measured signal obtained by a photosensitive element, will be
shown on the oximeter’s display through process in electronic circuits and microprocessor.

7. When no or low signal is detected, the pulse oximeter will power off automatically in 8 seconds.
Fingertip pulse oximeter is a portable non-invasive device intended for spot-checking of oxygen saturation of arterial hemoglobin (SpO2)
and pulse rate of adult and pediatric patients in hospitals, hospital-type facilities.
1. Install two AAA batteries according to the Battery Installation instructions.
2. Place one of your fingers into the rubber opening of the pulse oximeter.
3. Press the switch button one time on front panel to turn the pulse oximeter on.
4. Keep your hands still for the reading. Do not shake your finger during the test. It is recommended that you do not move your body
while taking a reading.
5. Read the data from the display screen.
6. Press the button again to toggle between six display modes.
After turning on the Oximeter, each time you press the power switch, the Oximeter will switch to another display mode.

Note:
A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor or sensor. Clinical testing is used to establish the
SpO2 accuracy. The measured arterial hemoglobin saturation value (SpO2) of the sensors is compared to arterial hemoglobin oxygen
(SaO2) value, determined from blood samples with a laboratory CO-oximeter. The accuracy of the sensors in comparison to the
CO-oximeter samples measured over the SpO2 range of 70%~100%. Accuracy data is calculated using the root-mean-squared
(Arms value) for all subjects, per ISO 9919:2005, Medical Electrical Equipment–Particular requirements for the basic safety and essential
performance of pulse oximeter equipment for medical use.
A functional tester is used to measure how accurately Fingertip Pulse Oximeter is reproducing the specified calibration curve and the
PR accuracy.
The model of functional tester is Index2 FLUKE simulator and the version is 2.1.3.
