The oximeter is designed to measure the percentage of arterial oxygen saturation of functional hemoglobin. Any of the following conditions may reduce the performance of the oximeter:

– Flickering or very bright light
– Bodyweight less than 44lbs (20kgs)
– Venous pulsations
– Cardiogreen and other intra-vascular dyes
– Methemoglobin
– Artificial nails or fingernail polish- Patients with an abnormal circulation of finger endings caused by COPD.| – Moisture in the oximeter
– Weak pulse quality (low perfusion)
– Low hemoglobin
– Carboxyhemoglobin
– Dysfunctional hemoglobin
– The finger is too cold
---|---

THE BASICS

The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the O2 concentration in the blood. It is an important bio- parameter for expiration. A number of diseases relating to the respiratory system may cause the decrease of SpO2 in the blood, furthermore, some other causes such as the malfunction of the human body’s self-adjustment, damages during surgery, and the injuries caused by some medical checkups would also lead to the difficulty of oxygen supply in the human body.
The corresponding symptoms would appear as a consequence, such as vertigo, impotence, vomit, etc. Some symptoms may be serious enough to cause significant harm.  Therefore, prompt information concerning the patient’s SpO2 can help doctors discover potential problems and is of great importance in the clinical and medical field.
2.1 Principle
The Principle of the oximeter is as follows: an experience formula of data process is established making use of the Lambert-Beer law according to Spectrum Absorption characteristic of Reductive hemoglobin (Hb) and oxyhemoglobin (HbO2) in glow & near-infrared zones. The operation principle of the device is: Photoelectric Oxyhemoglobin section Technology is adopted in accordance with Capacity Pulse Scanning Recording Technology so that two beams of different wavelengths of light can be focused onto the human nail tip through a perspective clamp finger-type sensor. The signal is obtained and measured by a photosensitive element. The information acquired will be shown on screen through treatment in electronic circuits and microprocessors.

INTRODUCTION
