Santamedical SM-210 Fingertip Pulse Oximeter OPERATOR’S MANUAL

Santamedical SM-210 Fingertip Pulse Oximeter

General Description

Oxygen Saturation is a percentage of Oxyhemoglobin (HbO2) capacity, compounded with oxygen, by all combinative hemoglobin (Hb) capacity in the blood. In other words, it is the 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, and 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 a small size, low power consumption, convenient operation, and portability. It is only necessary for a patient to put one of his fingers into the fingertip photoelectric sensor for diagnosis, and a display screen will show oxygen saturation. It has been proven in clinical experiments that it also features high precision and repeatability.

Measurement Principle

The 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 the glow 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 wavelengths of lights (660nm glow and 940nm 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 the process in electronic circuits and microprocessor shown on the Oximeter display through electronic circuits and a microprocessor.

Product Operation Scope

Fingertip Pulse Oximeter is a portable non-invasive, spot-check, oxygen saturation of arterial hemoglobin (SpO2) and pulse rate of adult and pediatric patients at home, and in hospital (including clinical use in internal medicine/surgery, anesthesia, intensive care and etc). The device is not intended for continuous monitoring. The PULE OXIMETER requires no routine calibration or maintenance other than the replacement of batteries.

10. Inaccurate measurements may be caused by autoclaving, ethylene oxide sterilizing, or immersing the sensors in liquid may cause inaccurate readings.
11. Significant levels of dysfunctional hemoglobins(such as carboxy-hemoglobin or methemoglobin).
12. Intravascular dyes such as indocyanine green or methylene blue
13. SpO2 measurements may be adversely affected in the presence of high ambient light. Shield the sensor area (with a surgical towel, or direct sunlight, for example) if necessary.
14. Excessive patient movement may cause accurate readings.
15. Venous pulsations may cause accurate readings.
16. Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line may cause accurate readings.
17. The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia.
18. The patient is in cardiac arrest or in shock.
19. Fingernail polish or false fingernails may cause inaccurate SpO2 readings.
