Wireless Low-Cost Bioimpedance Measurement Device for Lung Capacity Screening
Abstract:
This paper presents the development and implementation at a prototype level of a wireless, low-cost system for the measurement of the electrical bio-impedance of the chest with two channels using the AD5933 in a bipolar electrode configuration to measure lung volume variation. 15 volunteers were measured with the prototype, and the acquired signal presents the phases of the respiratory cycle, useful for the breathing rate calculation and for possible screening applications.

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
