Dr. Ching : What kind of a load can you han- 
dle, in addition to this other, numerically? 
Mr. Uretz: When you say a load I'm not 
quite clear what you mean ? 
Dr. Ching: Well, if we have the patient 
being monitored continuously and then for spe- 
cific moments during the day, can we call it in ? 
Mr. Uretz : Yes. 
Dr. Ching: Is there a limit to the number of 
times we could call it in ? 
Mr. Uretz : No. there would be a limit to the 
number of channels you can monitor at one 
time. We have a maximum sampling rate of 500 
samples per second and we can do about ten 
channels at that rate. If you go down to 100 
samples per second, you can be monitoring 
about 50 channels. And probably while it's going 
on, all these other tests will be handled with no 
more than perhaps a slight sluggishness, if you 
had a tremendous number of terminals. The 
main thing that could slow you down is to sample 
to many channels to fast.
