title: Programmable calculator: a program for use in the intensive care unit.
abstract: A program has been prepared for use in a small programmable calculator to allow the rapid and accurate determination of derived data. Changes in oxygen availability, deadspace and shunt fraction can be obtained in a few seconds and therapy altered accordingly. FIO2 required to produce a desired PaO2 can be obtained using the iso-shunt concept.
