File Link is on the 1.6.2 CD Release Tools such as File Link, DB2MDW, BDT, and Patient number checkers were previously removed from the 1.6.1 CD release. They have now been returned to the 1.6.2 CD. The latest version of File Link 3.0 is on the CD. Database Version Change CPWS 1.6.2 has an updated database version. This means that databases constructed from previous versions of CPWS (including 1.6.0 and 1.6.1) will need to be upgraded before the 1.6.2 software can access them. Databases can be made compatible by installing the 1.6.2 database on the database server or executing DBBuilder.exe on the Database server. Enhancements: o Resting ECG Changes New Pediatric interpretation The algorithm is the same as the CP200: o Can handle both Standard and Pediatric lead set (V3R, V7 for V3, V5) o Adult vs. Pediatric algorithm is now always chosen on the basis of age (used to be based on lead set) o No separate license option for Pediatric anymore: if interpretation is enabled, Pediatric is also enabled. Customer Service no longer has to worry about selecting the Pediatric interpretation option. o Note: Pediatric lead set implementation in CPWS is still the same as it was, and is therefore different than CP200. 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 3 of 14
Pediatric Lead Set differences: CPWS vs. CP200 CPWS expects the user to apply the electrodes in the appropriate locations, and then attach the leads in sequence from right to left. CP200 uses standard lead placement for most leads, moves V3 to the V3R position and V5 to the V7 position. Pediatric Lead Placement Anatomical site (Right to Left) V3R V1 V2 V4 V6 V7 Lead wire CPWS V1 V2 V3 V4 V5 V6 Lead wire CP200 V3 V1 V2 V4 V6 V5 Added an auto-restart option for the Resting ECG acquisition to increase the chance of taking a good ECG. When any of the following issues happens, the recording will restart so the captured ECG will be clean: Framing-type errors caused by serial communication problems, for instance; on thin clients. Lead-off conditions. This new feature is active when recording 10-sec ECGs without pre-trigger. 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 4 of 14
If you re stuck in this resting ECG restart mode because of continuous errors, you can override the restart feature through a new button: ECG printing will automatically select thicker lines on high-resolution printers (also for Stress): 1.6.1 1.6.2 Can also still use Pen.Width = 2 in.rtm files 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 5 of 14
o Exercise ECG Changes METS interpolation METS values change gradually after load changes. Setting for minimum last stage duration has become obsolete with this improvement, but was not removed. 1.6.1 1.6.2 Interpolation slope can be changed in registry, HKEY_LOCAL_MACHINE\SOFTWARE\Cardio Control\MDW\Modules\Cardio Perfect ST\METS, TimeConstant_Treadmill, default = 120 TimeConstant_Ergometer, default = 40 ST bar chart colors follow ECG curve superimpose reference and current colors. Fixed bug that would delete stress variables from all tests when only one test was deleted. 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 6 of 14
o Spirometry Changes CPWS 1.6.2 meets ATS2005 compliance acceptability and repeatability Real-time curve display improved Centering and scaling used to be problematic for large volumes Exhale timer (Note: The Duration timer is designed for timing an effort per ATS guidelines. This is not a total effort timer and will reset to zero when backflow is detected.) Start of expiration fixed on x=0 Mild restriction was not always diagnosed correctly. Fixed reports where long parameter list was truncated. Flow values in best composite effort will all be from the same effort, volumes from whatever effort has the best value for that parameter (ATS spec) Improved end of expiration detection. For obstructed patients, 1.6.1 could underestimate FVC: 1.6.1 1.6.2 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 7 of 14
If there is more than 1 inspiration, the one with Max(FIVC+FIV1) will be part of the FVC loop. (1.6.1 used only PIF) In this case, 1.6.1 would have selected the wrong inspiratory part because the PIF is larger. Tidal V/T and F/T curves added: Tidal V/T Selected V/T 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 8 of 14
Parameters used for FEV1% calculation will always be shown: Interpretation strings will now show the translation. Interpretation also includes reversible airflow obstruction and bronchodilator response Fixed scaling on Social Security report. SVC predictions added to Hedenström. Post effort with long medication string was not saved. This has been corrected. Pre and Post curves are better distinguishable in Black and White report prints. SVC final result sometimes showed more than only best pre and best post. Corrected. Wang prediction norm has been added. Calibration data is saved for all users recalibration is no longer necessary when someone else logs in. 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 9 of 14
o Database Changes Fixed issue where Vista Sync Center would close CPWS database connection MS SQL 2005 compatibility CPWS 1.6.2 can connect to SQL 2000, SQL 2005, SQL 2008 servers. During installation, customer can choose between SQL 2000 MSDE (max. 2GB) and SQL 2005 Express (max. 4GB) for free local database engine installation. The reason for this choice is that 2005 Express can take up to 20 minutes to install. Use the SQL 2005 Express option for connecting to SQL 2005 or 2008 servers. Be aware that with the SQL 2005 Express option installed, there is no longer the option run or schedule backups within the Administrator tool. Backups may be possible with third party software. Tolerance for intermittent network When connection to the database is lost, CPWS will automatically try to reconnect. If saving data to the database did not succeed, a local.mdw file will be generated (ECG, Stress, Spiro) in the My Documents folder. Stored procedures for HIPAA log on/off now switch only the HIPAA-log related triggers. Pre-1.6.2 would also disable CPSAPI triggers. Added and changed Spiro norms. o Installation Changes During installation, US defaults is automatically selected when in US locale 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 10 of 14
Installation can be pushed out through Windows Active Directory installs automatically on many workstations from one central server (refer to the Install manual on the CPWS CD). Note: It is expected that the customer using this option will have a qualified IT systems engineer on site that has knowledge and experience to follow this install process. 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 11 of 14
o FileLink Changes FileLink is now a plug-in: Adds PDF and XML output capability Plug-in makes it compatible with thin clients Preferences are set-up through a menu on the FileLink plug-in Manually save tests by clicking the button on the FileLink tab in the module area. 20011473 - TSB - CPWS 1.6.2 Software Release Rev A Page 12 of 14
