IMPORTANE OF PATIENT MONITORIN
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
system
IT IS ESSENTIAL THAT THESE ELEMENTS ARE MONITORED
FREQUENTLY AND REULARLY AND THAT ANY
OBSERVATIONS ARE IVEN PREEDENE OVER MAHINE
ONTROL PARAMETERS IN JUDIN THE STATE OF A
LINIAL PROEDURE
Before usng any montorng system or devce, the user must
check that t conforms to the relevant standards

WARNIN
If no ventlator s connected to the absorber, care must be
taken to ensure that the bag/ventlator swtch s kept n the
‘Bag’ poston, to avod gross loss of gas from the breathng

3.4 Adjustable Pressure Limiting (APL) Valve
The APL valve (1) s a sprng loaded plastc float wth a rubber
seal, provdng breathng system pressure control, and excess
pressure relef
The sprng pressure can be vared by rotatng the control
knob on top of the valve In the fully counterclockwse poston
the mnmum pressure s 10 cmHO at 6 L/mn Ths can be
ncreased by clockwse rotaton to 60 cmHO
As shown n the graph, further clockwse rotaton causes a
rapd ncrease n openng pressure so that n the fully closed
poston, the valve functons as a 60 cmHO excess pressure
