Merge hemo provides a single server for multiple facilities and departments and allows the user integrate data collection, waveform analysis, inventory control, patient charging and procedure reporting into a single system.This results in a cath lab that is more streamlined, efficient and cost-effective.The touch-screen interface and user-defined workflow eases the transition for physicians and staff.The customer contacted merge on (b)(6) 2012 to report that the tabs have locks on them, but when selecting the lock no hostname is displayed.Merge fixed the error in sql so that case folders where no longer locked by a phantom workstation.Merge explained that this is no longer an issue in later merge hemo releases.The system is designed to allow users to lock a study or tab within the study to make changes.This ensures that two users can not make changes to the same study at the same time.However, in some instances the system will lock tabs within a study even when a second user does not have the study open on a different workstation.This "phantom" lock mimics the behavior described above except the lock is not caused by a second user but by the sql table.The lock might prevent users from calculating certain calculation that are required during the procedure since height and weight might be unavailable.(b)(4).
