Ambulator mobilization against thromboembolism.

CHEST/85/5/MAY,1984 713 value, befure bronchodilation, the same expressed as the percentage predicted, the measured values after bronchodilator, and the percentage change. Although this is a large amount of data, we think that the form we have chosen is clear and easy to interpret (Fig 1). Two graphs showing flow/volume loops are given on the report. The first depicts the predicted loop, plotted at predicted lung volumes, with, superimposed, the pre-bronchodilator loop, plotted at the measured long volume. The latter is replotted on the second graph for comparison with the post-bronchodilator loop, again plotted at the measured post-bronchodilator lung volume. Any test not required for a particular patient is left blank. The full report, as shown, is printed by a dot matrix printer in less than 2 minutes using data stored on a floppy disk. We think that our format, which presents the full range of standard pulmonary function tests, demonstrates that a combined numerical and graphic form can be used to provide a report which is easy to interpret.
