Haemoglobin Measurement: Haemoglobin measurement stands as the central focus of this innovative project, and for good reason. Haemoglobin, the oxygen-carrying protein in our blood, serves as a paramount indicator of overall health. Accurate and timely haemoglobin assessment is essential for the early detection and management of various medical conditions, including anaemia, blood disorders, and certain chronic illnesses.
Unique Purpose: What sets this project apart is its unique purpose in redefining Haemoglobin measurement as a non-invasive procedure. Traditional methods of Haemoglobin assessment involve the extraction of blood through needles, a process fraught with discomfort and fear, particularly for individuals grappling with trypanophobia (fear of needles). By introducing a non-invasive approach, this project eliminates the distressing element associated with needle-based tests. The process is made more comfortable and accessible, allowing even those with severe needle-related fears to easily undergo Haemoglobin monitoring.
User-Friendly: The non-invasive nature of this innovation makes it inherently user-friendly, creating a healthcare experience that is more accessible and welcoming to all. It empowers individuals to take charge of their health, offering a seamless and painless method for immediate and continuous Haemoglobin assessment.
2.3.1 SpO2 Measurement (Algorithm-I) :- Role in the Project: SpO2 (oxygen saturation) measurement is the linchpin in this project, serving as the bridge that connects non-invasive technology to the calculation of Haemoglobin levels. As a non-invasive method, SpO2 measurement assesses the percentage of oxygen-bound Haemoglobin in the blood.
How it Works: This algorithm works by calculating the ratio between the Infrared & Red LED readings which is known as the R-index. And by using the Calibration Curve & R-index, SpO2 value is calculated. The relation used to calculate it is SpO2 value = calibration curve(R-index).
Application in Haemoglobin Measurement: The application of SpO2 measurement is essential in the project's pursuit of non-invasive and real-time Haemoglobin level estimation. It not only ensures the comfort and convenience of healthcare assessments but also extends its inclusivity to individuals who might have otherwise avoided necessary blood tests. SpO2 plays a central role in making healthcare more accessible, user-friendly, and ultimately more effective in the calculation of Haemoglobin levels.
