A multitude of clinical research studies have validated the superiority of impulse oscillometry (IOS) over spirometry because it is far more sensitive in the detection of pulmonary diseases and since it is effort-independent, it can be successfully used in children as young as six-months old. By miniaturizing the IOS to be a hand-held and portable device, the present invention takes IOS technology out of the exclusive environments of the research lab and specialty Pulmonology office. Also by advancing the technology, the manufacturing cost is greatly reduced thereby making the device affordable and available to the average primary care physician for use in their office. In addition, as the present invention becomes available as a home-use device, it will significantly improve the home management of complex respiratory diseases, i.e., Asthma and COPD. The present invention, being a miniaturized and electromagnetically piston-driven IOS, is truly unique in its concept and technology.
