DISCUSSION 
N. P. Ching, St. Vincent's Hospital, New 
York City: It seems as though your system is 
really the routine hospital lab computer. If I 
were doing, say a dog or we had a patient being 
monitored over a one hour period, can your sys- 
tem handle the various variables, like blood gas, 
cardiac output, etc. ? 
Mr. Uretz : Yes, basically our processors are 
called as needed. You would never sit with a 
program in for an hour. We're in the process of 
doing the equivalent of what Sam Topham was 
talking about for routine long-term monitoring. 
This means that we will be building additional 
software so that periodically the appropriate 
program gets called upon and loaded-in to do 
the job. We've gone about this in the other way, 
going to the lab data first. We have on some 
demand physiological measurements and later 
we will add this other capability. But the basics 
are there. It's just a new structure to be built on 
top.
