What is a Pulse Oximeter?
Pulse Oximeter
It is a small device which easily measure oxygen saturation level of blood in human body. The pulse oximeter will be able to tell us oxygen saturation levels along with our heart rate. It is a noninvasive procedure to measure the oxygen saturation level of human body. It is a clip type device which used on finger or ear lobe. Pulse oximetry works on the principle of spectral analysis for measurement of oxygen saturation.
Construction of Pulse Oximeter
There are various components used in Pulse oximeter such as
- Red Led
- Infrared Led
- Photo diode
- Microprocessor
- Display
- Power source
How pulse oximeter work
Red Led and Infrared Led, emitted light rays and transmit through the tissue then the photo diode receive or detect the light rays and convert in electrical signal and this signal goes to the microprocessor. The microprocessor unit analysis and display it.
RED LED and IR LED
Pulse Oximeter Having two LEDs for the purpose of light rays generation. These LEDs rating are Red LED 660nm and Infrared LED 910nm wavelengths.Photo Diode
The photodiode detects the light transmitted through both pulsatile and non-pulsatile tissues. The photodiode measures the amount of light absorbed at each wavelength, from which the amount of oxygenated hemoglobin and deoxygenated hemoglobin is calculated by a microprocessor and displayed on the monitor.
Microprocessor
In this unit do the calculation and activation of alarm for if low oxygen saturation level of human body
And also measure pulse rate of body.
Advantages of Pulse Oximeter
- Easily available in market.
- Low cost
- Easy to use
- Flexible fit ,all finger sizes from adult to pediatric function.
- Reliable ±2% accuracy with proven clinical data
- Accurate to 70% saturation
👉In the present time our life styles are going on busiest schedule so our body needs selfcare and healthcare.

What is normal reading pulse oximeter?
Oxygen saturation level between 95% and 100% is regarded as normal for a healthy person at sea level. At higher elevations, oxygen saturation levels may be slightly lower.
What are the signs of low oxygen?
Some symptoms like
- Headache.
- Difficulty breathing
- Rapid heart rate
- Coughing.
- Confusion
- Bluish color in skin
What are the different types of pulse oximeter?
- Fingertip.
- Benchtop.
