Description:

Handheld Pulse Oximeter with Real-Time Measurements, External Finger Probe, Advanced-Data Storage and Review Functions

The Handheld Pulse Oximeter's main purpose is to measure and record the pulse rate and functional oxygen saturation (SpO2). It can be used for both clinical and domestic usage.

 

What is SpO2? 

The percentage of oxygen saturation found in the blood is called SpO2. It is determined by the total hemoglobin of the arterial blood and the oxyhemoglobin's (HbO2) percentage. To reflect the respiration function, the SpO2 acts as a vital physiological parameter. The formula can be defined as:

SpO2 = HbO2/ (HbO2 +Hb) ×100%

The hemoglobin that releases oxyhemoglobins (oxygenized hemoglobin) is HbO2.

Default Low Limit and Range of Normal SpO2:

Hypoxia is determined with the SpO2 value drops below 94%, commonly in healthy people. So, the SpO2<90%, according to most researchers, is the default threshold for determining anoxia. Thus, SpO2 is generally set at a low limit of 90%. 

Factors that affect the SpO2 accuracy (interference reason):

1. Intravascular dyes such as indocyanine green or methylene blue
2. Exposure to excessive illumination, such as surgical lamps, bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight.
3. Vascular dyes or external used color-up product such as nail enamel or color skincare
4. Excessive patient movement
5. Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line
6. Exposure to the chamber with High-pressure oxygen
7. There is an arterial occlusion proximal to the sensor
8. Blood vessel contraction caused by peripheral vessel

 

Factors causing low SpO2 value (pathology reason):

1. Hypoxemia disease, functional lack of HbO2
2. Pigmentation or abnormal Oxyhemoglobin level
3. Abnormal Oxyhemoglobin variation
4. Methemoglobin disease
5. Sulfhemoglobinemia or arterial occlusion exists a near sensor
6. Obvious venous pulsations
7. Peripheral arterial pulsation becomes weak
8. Peripheral blood supply is not enough
