The equipment is just a clinical diagnosis of auxiliary equipment. The physiological data displayed on the equipment are for reference only and can not be directly used for diagnostic interpretation.
Not suitable for the users with arrhythmia/heart failure/Low perfusion (PI<0.3)/finger trembling.
Not suitable for the users with large finger size or exceeding pulse oximeter’s finger measurement cavity size.
Please don’t use the thumb and tail finger to measure.
Discomfort or pain may appear if using the equipment ceaselessly, especially for microcirculation barrier patients, it recommended that the equipment should not be used on the same finger more than 5 minutes.
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
- Moisture in the oximeter
- Body weight less than 44lbs (20kgs)
- Weak pulse quality (low perfusion)
- Venous pulsations
- Low hemoglobin
- Cardiogreen and other intra-vascular dyes
- Carboxyhemoglobin
- Methemoglobin
- Dysfunctional hemoglobin
- Artificial nails or fingernail polish
- The finger is too cold
- Patients with abnormal circulation of finger endings caused by copd.

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 respiration. 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 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 patients SpO2 can help doctors discover potential problems, and is of great importance in the clinical and medical field.

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 Inspection 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 microprocessor.
