ABSTRACTBackgroundAmong the most basic measures of respiratory function is the total lung capacity (TLC). TLC is the pulmonary gas volume at maximal lung inflation, which is the sum of the volume of gas that can be exhaled –the vital capacity (VC)– and the volume of gas that cannot –the residual volume (RV). Determination of VC requires only spirometry whereas determination of RV or TLC requires body plethysmography, gas dilution or washout, or thoracic imaging, each of which is more complex than spirometry, and none of which is suited to routine office practice, population screening, or community medicine. To fill this gap, we describe here a new approach to determine TLC without plethysmography.MethodsIn a heterogeneous population of 434 volunteers (265 male, 169 female; 201 healthy, 170 with airflow obstruction, and 63 with ventilatory restriction), we determined TLC in the standard fashion using conventional body plethysmography (TLCpleth). In the same individuals, we also determined TLC in a novel fashion using the MiniBox ™ (TLCMB). To obtain TLCMB, population-based data from traditional spirometry together with flow-interruption transients were subjected to data mining and machine-learning to create for each individual subject an unbiased statistical determination of TLC.ResultsFor the combined heterogeneous population, we found TLCpleth = 1.02TLCMB −0.091 L, adjusted r2=0.824. For the heterogeneous population as a whole, and for each subpopulation, TLCMB closely tracked TLCpleth. For 26 healthy subjects measured on different days, the coefficient of variation for repeated measurements in was 3.3% for TLCpleth versus 1.6% for TLCMB.ConclusionsThese results establish the validity and potential utility of a new method for rapid, accurate, and repeatable determination of TLC in a heterogeneous patient population, but without the need of a plethysmograph.
