Introduction

A heart rate pulse oximeter is a non-invasive device used to measure the oxygen saturation level (SpO2) and pulse rate of an individual. It provides quick and accurate assessments of how effectively oxygen is being carried by blood cells throughout the body.

Components of a Pulse Oximeter

The primary components of a pulse oximeter include:

• LED Emitters: Typically, a red light (approximately 660 nm) and an infrared light (approximately 940 nm) are used to differentiate between oxygenated and deoxygenated hemoglobin.
• Photodetector: Captures the light that passes through the tissue, which varies based on the blood's oxygenation level.
• Microprocessor: Analyzes the light absorption data and calculates the SpO2 and pulse rate.
• Display: Shows the real-time readings of oxygen saturation and heart rate.

Mechanism of Operation

The pulse oximeter operates based on the principle of spectrophotometry. It emits light through a translucent part of the body, such as a fingertip or an earlobe. As blood pulses through the vessels, the device differentiates the oxygenated hemoglobin from deoxygenated hemoglobin based on light absorption characteristics.

The ratio of absorbed red and infrared light allows the microprocessor to calculate the SpO2 level, typically expressed as a percentage. It simultaneously detects the pulse by sensing tiny variations in the volume of blood with each heartbeat.

Parameters and Numerical Analysis

• Oxygen Saturation (SpO2): Healthy individuals typically display an SpO2 range of 95% to 100%. Levels below 90% can indicate hypoxemia.
• Pulse Rate: Normal resting heart rate for adults ranges from 60 to 100 beats per minute (bpm). Variations can signify conditions such as bradycardia or tachycardia.
• Accuracy: Most medical-grade pulse oximeters have an accuracy specification of ±2% in the 90% to 100% SpO2 range.
