Measurement of Lung Function Using the Magnetometer System.

Abstract

In the last few years, several investigators have studied the idea of estimating lung volume by measuring the dimensional changes of the chest and abdomen during respiration. The prospect of being able to know the value of lung volume from information obtained noninvasively was intriguing. The most common method of measuring the dimensional changes is to use magnetometer pairs. For the purpose of this report, it is sufficient to note that magnetometer pairs generate a voltage that is proportional to the change in their separation distance. The relationship between voltage and the change in separation distance is essentially linear over the separation distances measured in this study.
