In this paper we present an atypical method for measuring respiration volume. We infer heart rate variability (HRV) from an electrocardiogram (ECG) and present results from a pilot study of 6 participants to validate measuring respiration volume from HRV in comparison to the Cosmed K4b(2). We show a qualitative correlation and trend between the known respiration volume as measured by the Cosmed K4b(2) and the new method for measuring lung volume. From these results, we propose guidelines for an in-depth study of measuring respiration volumes from heart rate variability.
