STANDARD SPIROMETRY (SLOW AND FORCED)The Spiro’Air ® incorporates all the functions and performancesneeded to measure slow and forced vital capacity.The flow is measured by the pneumotachograph and the volume ismeasured by true volume displacement.Tests under bronchodilator or bronchoconstrictor are simplifiedby the specifically adapted software functions (comparison table,effect-dose curves, test protocols, ...)Additionally, incentive spirometry assists the measurements withchildren. Post visualisation and Post treatment give a convenienceof use particularly appreciated: Choice of graphical representation,selection of calculation points, alignement of the flow / volumecurves on RV, time evolution of measured parameters by numericalor graphical representation, deletion of poor effort, ...FRC HEThe Spiro’Air is fully equipped for FRC measurement by theclosed circuit He dilution technique with CO2 absorption and O2compensation. The latter is required to compensate for burnt up O2during breathing.This technique is fully automated and requires minimal userintervention.During the procedure, 2 fast moving fans fill up the Spiro’Air bellwith a mixture of room air, 100% He and 100% O2 (2 gas cylindersare needed).The recording of the ventilation and the gas concentrations isviewed in real time, during the test, to facilitate the understandingof the measurements.As for spirometry, all the software functions needed for the measurements,under the best conditions, are integrated in this option.MEASUREMENT OF DIFFUSION CAPACITY DLCOUNIQUE the only manufacturer offering the choice of 4 diffusionmethods :Single Breath using the helium trace gas HeThe well known technique described by J.E. Cotes based on theJones Meade method. Using a bag collection system the subjectcan be controlled for inspiratory volume, washout (discard) volumeand sample volume. This method has proven repeatability and themethod was the same as that used to collect the predicted valueswe use today.DLCO-NO (TRACE GAS HE) NEW & EXCLUSIVEMembrane diffusion and capillary blood volume (Dm & Qc)measurement.Regarded as the ‘True’ diffusion characteristic and the most usefulindicatorof membrane thickening, this measurement takes on anew lease of life. The powerful Exp’Air software makes the calculationspainless, the combination of NO and CO follows the work of Prof.Guenard of Bordeaux. Simple to perform and rapid results add thistest to the list of favourite studies undertaken in routine practice.Additionally, this measurement can be performed in conjunctionwith NEP,the pulmonary blood flow and its ability to recruit fromthe capillary reserve can then be evaluated.Single Breath using Methane trace gas (CH4)Using fast gas analysis, this method collects the exhaled breathdirectly as a high resolution data array. This has the advantage thatpost test analysis can be performed aligning the start of sampleonto the alveolar plateau after the clearances of all the deadspaces. A sample as low as 50 ml can be used to calculate thediffusion. This can overcome the volume limitation of other systemsand methods.Intra Breath diffusionThe sample is taken during a slow and constant exhalation in therange of 200 – 500 ml/sec. Applying linear regressions to the dataarray of the expiratory gas, the alveolar concentrations are calculated.As this method requires no breath holding, it will greatlybenefit some subject groups.Steady State diffusion Tlco ss NEW & EXCLUSIVEMedi-soft has taken a new look at this method, using fast gastechnology and replacing the older bulky instrumentation this is a“NEW” method for a new age of diffusion measurement. Requiringminimal subject effort, this method is especially helpful for obtainingmeasurements with children and reluctant subjects. Performedat a steady state breathing condition, the measurement is valid assoon as the subjects ventilation is uniform and stabilized.NEP (option) EXCLUSIVEA new and very sensitive test that is specific and reproducible fordetermining the degree of expiratory flow limitation both at restand during exercise, particularly with subject’s known to haveobstructive lung disease. The test applies a negative pressureto the mouthpiece during the expiratory phase, this permits thecomparison of the flow volume loop with the tidal efforts whenreviewed as a flow volume loop display.This method also allows the indirect measurement of the resistance(R Nep) which provides a good alternative to the standardscreening method.RINT (option)RintMeasurement of the total pulmonary resistance by the method ofairflow interruption (during 80 to 120 ms) at each respiratory cycle.• Visualization of the mouth pressure in real time with calculationpoint for each cycle.• Choice between 3 mouth pressure calculation methods.• Averaging of the value with rejection by “Gauss’s curve” method.• Automatic functions indentical to the spirometry ones for testwith bronchodilator and bronchoconstrictor.• These measurements are taken in passive mode.VENTILATION MECHANICS (option)• MIP - MEP : Maximum Inspiratory and Expiratory Pressure.• SNIP : measurement of the maximal nasal inspiratory pressure.FENO (option)External module for the measurement of exhaled endogenous NOby the off-line methodprovo ii (option)Equipment for fully automated bronchochallenge tests with automatednebulizer . This option provides full control of products anddoses used and of test performing criteria for bronchochallengetesting.
