An excerpt from USE OF A PROGRAMMABLE CALCULATOR IN CARDIOPULMONARY PERFUSION , Cardiovascular Diseases, Bulletin of the Texas Heart Institute, Vol. 5, Number 2 (pgs. 156-166)
" This study describes a hand-held, battery-powered, programmable instrument (Calculator Model SR-52) that can be taken directly into the operating room by cardiopulmonary perfusionists. Three programs are described in detail:
1) Cardiopulmonary perfusion parameters and estimated blood volume;
2) blood gas parameters and saturations, with temperature corrections;
3) cardiopulmonary oxygen transfer and oxygenator efficiency.
This inexpensive calculator allows perfusion personnel to manipulate easily-derived data into values which heretofore have required elaborate nomograms or special slide rules-or were not available within a reasonable computational time. "
FULLY documented.
BEST!
