MasterScreen Body Diffusion

Economically oriented, bodyplethysmographic measuring system with integrated diffusion unit.

Economically oriented, bodyplethysmographic measuring system with integrated diffusion unit for the determination of:

• Slow and Forced Spirometry (inspiratory and expiratory Flow-Volume Loop and Tiffeneau Test)
• Partial Lung Volumes by Bodyplethysmography: Intrathoracic Gas Volume (ITGV, FRCpl), Residual Volume (RV) and Total Lung Capacity (TLC)
• Airway Resistance, Conductance and specific Resistance (Rtot, Reff, R0.5, Rmid)
• Closing Volume
• Lung Subvolumes by inert-gas methode: Functional Respiratory Capacity (FRC), Residual Volume (RV) and Total Lung Capacity (TLC)  
• Diffusion Capacity of the Lung and Krogh-factor

Security test according to DIN IEC 601-1 and VDE 0750

Bodyplethysmograph

• Fully glazed box with integrated sensors for box and mouth pressure as well as easy-to-exchange, heated Jaeger pneumotach for an exact determination of flow and volume and a quick shutter
• Maximum patient comfort by height-adjustable seat and easy-to-handle support arm
• Compensation box for optimum artefact suppression

Support Arm

• Demand valve unit for direct breathing from pre-mix gas container (no inspiratory bag)
• Very precise and durable gas analyzers for carbon monoxide (CO) and Helium (He), mounted inside the Body-box

Signal Processing

• High integrated interface card with 12 bit A/D converter and programmable preamplifiers. Computer-controlled zero adjustment and BTPS compensation.

Patient Data

• Entry of patient data and saving of this information in the data base.
• Calculation of predicted values, either according to ECCS or US standards, with graphical and numerical display during the measurement and in measuring reports.
• Very fast access to all patient data through an optimized storage algorithm including automatic data decryption
• Backup of data either on floppy disks (standard) or automatically with streamers (option)

Data Recording

• JLAB software with modules for measuring, organization and communications. Contemporary user environment based on Microsoft Windows including easy operation by mouse- or keyboard including text editor and graphics package. The flexible software facilitates adjustments to measurement routines, selectable protocols with a choice of parameters, predicted values and graphics in a pre/post comparison or as provocation series.
• Storage of all patient data, measured curves (e.g. of Spirometry, Flow-Volume, Bodyplethysmography etc.) as well as all calculated parameters. The capacity of the data base depends on the size of the used storage medium, i.e. it is possible to store 30.000 - 50.000 tests on a 500 MB hard disk.
• Functions for easy deletion of selected (time criterion) patient records

Parameters

• Slow Spirometry: VT, BF, MV, ERV, IC, IRV, VCin, VCex, VCmax, Ti, TE, Ttot ...

• Maximal Voluntary Ventilation: MVV, BF_MVV, VT_MVV
• Bodyplethysmographic Resistance: Rtot, RtIn, RtEx, Reff, ReffIn, ReffEx, R0.5, Rmid, Gtot, sRtot, SReff, ...
• Partial Lung Volumes (Bodyplethysmography): ITGV (FRCpl), RV, TLC, RV%TLC ...

• Lung Subvolumina (Inert-gas Methode): FRC (He), RV, TLC, VA ...

Report

• Up to 100 free defined protocols available with individual selection of parameters, predicted values and graphics in a pre/post comparison or as provocation series.
