The pulse oximeter operates using photoelectric oximetry technology.
It measures the oxygen saturation in the blood, specifically the hemoglobin's oxygen saturation (SpO2). This indicator is critical for evaluating the respiratory system's performance, as many respiratory illnesses cause a reduction in blood oxygen levels.
How the pulse oximeter works:
The device analyzes the color spectrum of blood and displays hemoglobin's oxygen saturation as a percentage. When oxygen binds to hemoglobin, its structure and color change: from oxygen-deprived bluish blood passing through the lungs to bright red blood as hemoglobin becomes oxygenated.
Technology used:
Pulse oximeters combine pulse detection and recording technology. The device measures:
- Oxygen concentration in the blood (SpO2)
- Pulse rate via fingertip measurements.
Suitable for:
- Home use, hospitals, and healthcare centers
- Before, after, and during physical activity or sports.
Key features:
- Suitable for children
- Equipped with a SpO2 sensor and an LCD display
- Compact, lightweight, and portable
- Simple to use, with low power consumption
- Displays SpO2 values in percentage
- Graphical representation of pulse rate
- Low voltage indicator
- Automatic shutdown: the device turns off 5 seconds after removing the finger
