Development of an Fpga Based Smart Diagnostic System for Spirometric Data Processing Applications

Abstract

Abstract-The paper describes the development of an FPGA based fuzzy processing system for pulmonary spirometry applications predicting the approaching obstructive or restrictive pulmonary disorder of the patient before criticality actually occurs. The system employs a smart agent that accepts the Peak Expiratory Flow Rate (PEFR), Forced Expiratory Volume in 1 second (FEV1) and Forced Vital Capacity (FVC) data of patients. In order to speed up the computation process, hybrid parallel data processing architectures with dynamic scheduling mechanism have been employed leading to a speed up of approximately 12 times. The processor implemented on the FPGA can perform fuzzy inferencing at a speed of approximately 5.0 MFLIPS. The whole system is realized on Altera Cyclone EP1K6Q240C8 FPGA chip requiring 5,865 logic blocks. The system has been designed to be inexpensive, portable and user friendly for occupational health care applications in developing countries.Using the system, approaching pulmonary disorder of patients has been predicted with an accuracy of 95.83%.

Assessment of Lung Efficiency of Individuals Exposed to Various Foundry Industries in Satara City

“…Sterilization of mouthpiece was done every time before use. Severity of the pulmonary functions was determined as per Chowdhury et al, (2008) Hence, it shows that people of the large industry have comparatively intense respiratory problems as it is a highly polluted area than that of medium and small industries. Hard time breathing due to smoke 28 % 13 % 08 %…”

“…Air pollution exposure also triggers several cases of asthma, exacerbate (worsen) a previously-existing respiratory illness, and it leads to development chronic illnesses including lung cancer, emphysema and chronic obstructive pulmonary diseases (Kurt et al, 2016). For the manifestation of pathological condition, spirometry is a method through which measuring various lung volumes and airflow rates in and out of lungs (Chowdhury et al, 2008). Hence, spirometer is used to assess pulmonary function effectively.…”
