Low - Cost

Current spirometers on the market often have retail prices of over $1,000. As a result of this high cost, many physicians practicing in developing countries lack the resources to purchase spirometry equipment. The development of a low-cost, reliable spirometer would allow these physicians to make more quantitative assessments of their patients' pulmonary health. A standardized coaching program that would instruct and motivate patients through spirometric maneuvers would also prove beneficial to the reproducibility of results. To address these issues, three different spirometer designs have been proposed, all of which include a coaching procedure. By assessing the performance of each option in a variety of areas, our team selected a design and will pursue the manufacture and testing of it through the rest of the semester.
