The diagnostic value of spirometry as a tool for the early detection of chronic-obstructive pulmonary function restriction and other heart diseases is high. However, with the constant rise in the number of patients there is clearly a need to conduct pulmonary function tests on a routine basis. SCHILLER combined the two most frequently used cardiac/pulmonary function tests in one single unit: the CARDIOVIT AT-2 plus offers ECG and spirometry all in one product. This innovative device can be used for quick and easy initial clarification, for routine examinations of affected patients, and to monitor the progress of therapy. This "double winner" scores high, due to its low purchasing costs, its economic operation and the possibility of "double" reimboursement (for ECG as well as spirometry).

• 6-channel print-out in realtime at 5, 25 or 50 mm/s
• Automatic print-out function for 6 and 12 channels on one or two sides of the paper
• Fast, reliable, computer-aided ECG interpretation program including complete measurement for adult and pediatric ECGs (optional).

• Two tests in one – meaning double reimbursement from health insurance schemes
• Two different instrument functions – but only one operating system
• Easy to transport due to low weight and compact dimensions
• Maximum quality and absolute reliability
• The built-in printer supplies A4 print-outs in ready-to-file cardex format
• Print-out with diagnosis guidance and all measurements in less than 20 seconds
• Integrated rechargeable battery
• Expanded print-out possibilities and unlimited copying function
• Splash-resistant alphanumeric keyboard with direct function keys makes it quick and easy to enter patient data
• Possibility of saving test results for more than 60 patients (optional)
• Interface enables data transmission
• The curve quality of all 12 leads can easily be checked on the integrated 3-channel monitor – saving both time and paper!
• The repetition rate is cut to zero because the curve quality on the print-out is optimized using the SSF SCHILLER Smoothing Filter and the SBS SCHILLER Baseline Stabilizer.

• The unique SP-250 disposable sensor minimizes the risk of cross-contamination
• Compact size and low weight
• Calibration is simple and fast
• Inspiratory / expiratory tests: FVC, SVC, MV, MVV as well as pre and post medication tests
• Predicted value tables are stored for free selection.
• A4 print-out within seconds
• Visual patient support due to realtime curves and measurement information on the large screen.
