WARNIN
Anaesthesa systems have the capablty to delver mxtures
of gases and vapours to the patent whch could cause nury
or death unless controlled by a qualfed anaesthetst
There can be consderable varaton n the effect of
anaesthetc drugs on ndvdual patents so that the settng
and observaton of control levels on the anaesthesa system
does not n tself ensure total patent safety
Anaesthesa system montors and patent montors are very
desrable ads for the anaesthetst but are not true clncal
montors as the condton of the patent s also dependent
on hs respraton and the functonng of hs cardo-vascular
