Handheld Spirometer

Abstract

It is estimated that between 200,000 - 250,000 Norwegians are subject to theincurable disease COPD (Chronic Obstructive Pulmonary Disease), whichcounts for around 8.5% of the adult population. Only about one third of thoseare diagnosed, and need to go regularly to the doctor in order to monitor theprogression.The goal of this master project is to build a prototype circuit board that can beused to monitor those patients at home instead. Dierent methods for constructing such a device have been examined, and the solution consists of a spirometerthat can measure the reduction in vital capacity and send the measurements toa computer. Using the device will make the doctor spot the progression of thedecease, instead of only a one-time measurement. This project has constructed a user friendly, cheap and simple device, that is hopefully going to make the life of this patient group a whole lot easier.
