Innovations in intra-aortic balloon pump management: computer modem technology

The computer modem technology being developed by Datascope Corporation for the purpose of off-site intra-aortic balloon pump (IABP) monitoring was clinically evaluated in 30 patients requiring IABP support. The Datascope System 95 model IABP with built-in modem was used on all patients. Remote communications via a personal computer with modem were conducted under both routine and emergency settings. The Datascope PC IABP software was evaluated for its user compatibility, efficiency, diagnostic capability and overall usefulness as a clinical tool. During the eight month evaluation period, 87 remote communications were conducted for both routine and emergency IABP evaluation checks. Adjustments were recommended on 22 occasions relevant to balloon timing, trigger mode selection and augmentation volume settings. Eight communications were initiated in emergency settings due to a variety of patient conditions. Emergency intervention was successful in diagnosing and resolving critical situations including atrial arrhythmias, pacemaker timing, low cardiac output syndrome, loss of trigger source, catheter malpositioning and poor augmentation. The diagnostic capabilities and efficient means of data collection by the computer software provide the clinician with a valuable tool for routine IABP clinical monitoring, as well as emergency problem resolution.
