IntroductionThe SCHILLER SP-1 is a stand-alone pulmonary function testing unit that features fourmodes for the measurement of inspiratory and expiratory values. The unit incorporates aliquidcrystal display o instantlyshowthe test results. An integral high quality herm al printe rprovides clear and comprehensive result analysis in a number of differen t formats and anRS-232 interface is provided for transmission of test results to a PC. All tests and settingsare initiated via an easy to use keypad with ded icated test keys. Test indicators show thecurrent test be ing carriedout and function LEDs provide visual indication or func tions suchas power, sensor disconnected, paper tray empty and paper am. Measurementsare madewith a lightweight and hygienic open pneumotacho sensor. Two senso rs are available. TheSP-20 open pneumotacho sensor incorporates a disposable filter and is easily dismantledfor cleaning and sterilisation. The SP-150 sensor has a disposable, single patient senso r/filter assembly eliminating he need o clean the sensor after each use. The SP-1 has thefollowing features:

Direct function keys for measuring the following:FVC Forced Vital CapacitySVC Slow Vital CapacityM W Maximum Voluntary VentilationMV Expired or Minute VentilationLow weight and compact dimensionsBuilt-in rechargeab le battery for mains-independent useSelectab le printing ormats with integrated quality thermal printe rPatient memory for up to approximately 100 single measurements (op tion)Choice of 6 anguages for display and printing

LocationAs with a ll med ical units, the following general rules are to be noted:

The unit should not be stored or operated in a wet, hum id or dusty env ironment.The unit may not come into con tact with acidic steams or liquids.The unit should not be set up near radiology or diathermic systems, or near largetransformers or electrical motors. Ensure that a minimum distance of 1 meterbetween the unit and the mains supply is maintained

Potential Equalisation

In certain circumstances interference can be caused by external electrical equipment orradio equipm ent. Connect the earth potential equalisationconnection at the bac k of the SP-1 to the hospital common ground or, if acomm on ground s not present, to a metal ramew orke.g. the be d rame. Note that all other electrical equipment in close proximity should also beconnec ted o the same comm on ground. The part number of the po tential equalisationcableis 2. 310 005.

Power SupplyThe unit can be operated fromthe mains orfrom he built-in rechargeablebattery. The mainsconnection is on the rear of the unit. The mains indicator lamp is always lit when the unit isconne cted o the mains supply. A battery indicator lamp confirm s battery operation. Whenthe batte ry capacity is limited, the indicator flashes. To recha rge the battery, connect theapparatus to the mains supply by means of the supplied power cable. A totally dischargedbattery needs less than 15 hours to be fully recharged (60 in less than 3 hours).

A fully charged battery lasts approxi-mately 2 hours of normal use. Theunit can remain connected to themains supply without any danger ofdamage to either the battery or theunit.

Switching On and OffThe SP-1 is switched on and off withthe ON and OFF keys.

Wait 1 second.Press the START key

Note: Make sure that the flow sensor is kept still during the pumping operation.While pumping, the unit records the volume being pumped through the flow sensor andindicates it on the display.

Connect the calibration pump to the sensor. Ensure that there are no air leaksPress the CAL key - th e m enu is displayed as shown on the previous pageThe cursor is positioned at temperature. Enter the ambient temperaturePress ENTER when the correct temperature entered

* The predicted values (%)given on the printout may differ slightly from the values thatwould be obtained if manually calculated. The reason is that the measured a ndpredicted values on the printout are rounded to two decim alplaces, the processorhowever,uses the actual values -measured o three decimalplaces - to calculate heof predic ted value.

The post-medication ests are carried out in the same way as the premedica tion ests (threemeasurements stored). The printou t following post-medication ests will give the curves ofboth pre and post-medication tests (the premedication curve is bold). The measurementresults are shown as the best results (pre/post), results as a percentage of those predicted,(both pre and post) and the percentage change (i.e. difference) between pre and post-med ication results.The diagnosis resulting rom the premedication est is also given on this printout.

Diagnosis


59/82

The diagnostic interpretation is dependent upon the country. The factors used in theevaluation or diagnosis are automatically included in the respective language softw are anddescribed in the following chapters.Diagnosis Setting InternationalNote: When International i sset, diagnosticnormsarepredictedusing the VCvalue(if taken). If VC values are not recorded, FVC is used. T hat is:

%VC100 * NC /F VC predicted= 100 * VC NC predicted (when VC measurement taken ), otherwise

FEV% = 100 F E V lN C (when VC measurement taken), otherwise100 * F E V l / N C

Poss ible respiratory problems are diagnosed on evaluation of the following factors:

IObstructive I - I


60/82

Moderate ObstructionSevere ObstructionMild Restriction

Diagnosis Setting AmericanFor the USA and Canada, diagnosis of possible respiratory problems is bas ed on the ITSinterpretation standard which uses the LLN (Lower Limits of Normal) calculations . Thesecalculations apply to patients between the ages of 5 and 85. The LLN FEV1% value iscalculated as follows:

FEVl/FVC% s40 to 60% of LLNFEVl/FVC% s ~ 4 0 %f LLN/FVCpredicted is 60 to 80%

I IAdolescent I 19 to 25 yrs: IPredicted FEV1%x 0.848 19to 20vrs: IPredicted FEV1%x 0.805

Severe Restriction

I IChild Ie l8 yrs: I Predicted FEV1%x 0.826 I el 8 yrs: IPredicted FEV1%x 0.791

%FVCpredicted is 4 0

Using this LLN value , the diagnostic statements and their criteria are as follows:Diagnosis I CriteriaNormal limits I FEVl/FVC% predicted is >80% I
