title: Radiographic total lung capacity determination aided by a programmable calculator.
abstract: This report describes a method that was used to determine total lung capacity from routine chest radiographs, using a programmable calculator to facilitate computation. The results correlated closely with those obtained by a computerized method. The technique was rapid, inexpensive (the necessary equipment cost less than $400), and could be used in any pulmonary laboratory or office. The program is listed, and an example provided.
