We have investigated the effect of oxygen flow rate on pre-oxygenation in pregnant patients at term using a circle system. Twenty patients presenting for elective Caesarean section maintained tidal volume breathing through a standard circle system for 3 min. Subjects were pre-oxygenated using oxygen flow rates of 5 l.min(-1), 10 l.min(-1) and 15 l.min(-1)(More)
This tutorial will present the highlights of the SIMSCRIPT II.5 approach to building discrete event simulation models. The approach will be to construct a small example problem, implement the program in SIMSCRIPT II.5, and then to display the modularity which is possible with SIMSCRIPT II.5 by adding several “real-world” complexities to the(More)
There are at least three levels of abstraction to a simulation programming language. SIMSCRIPT II.5 is making significant progress on all three levels of abstraction. First, at the conceptual level, the long-established “world-view”—consisting of entities, attributes, sets and discrete events—has been extended to include processes(More)
The SIMSCRIPT 11.5 and MODSIM II programming languages are described. SIMSCRIPT 11.5 with its integrated graphical interface, SIMGRAPHICS, subst antially reduces time and effort in simulation model development. Its English-like syntax improves readability y of the code and. substantially reduces the need for documentation. MODSIM II is a modern(More)
