The newest card-programmable calculators are more flexible and powerful enough to process a variety of complex data, derive appropriate variables, and print the titles of the values and the results. These capabilities make the information derived from aggressive cardiorespiratory monitoring more usable, and specifically, have increased the benefits from the use of pulmonary artery catheters and techniques such as phonocardiography. A program using 800 steps and 20 memory registers and an illustration of the value of both the monitoring and calculator in ICU care are presented.
