| Abstract | Blood flow measurement has gained much importance over the years as it has a vital role to play in understanding the functionality of heart. There are many principles on which the blood flow measurements are based. This work aims at developing a non-invasive technique for measuring the blood flow using the optical sensors. Among the many optical sensors available, the photoplethysmography (PPG) sensors are capable of measuring blood volumetric changes in the subcutaneous vessels. The proposed method involves acquisition of a real time photoplethysmography (PPG) signal from a reflectance type of optical sensor designed and developed with light emitting diode (LED) as source and OPT 101 as the detector. After the acquisition, the signal is conditioned using appropriate circuitry. The conditioned signal is then displayed on to MATLAB via the microcontroller. The PPG signal so acquired will be analyzed on MATLAB in time domain to estimate the parameters related to heart like the stroke volume which is the area under the curve and the heart rate and thus calculate the blood flow/cardiac output. The proposed method of blood flow measurement is advantageous when compared to the traditional methods of measurement as this is a non-invasive technique and does not require any surgical intervention, it can be used to estimate the blood flow in subjects of different age groups, gender and infants as well. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
