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

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

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
