Monitoring monitors.

A centralized, remote alarm system was implemented to alert nursing personnel when patient monitors located in isolation rooms go into alarm. The design includes a method of confirming the ON/OFF status of individual monitors to avoid operator error. This system utilizes low-cost individual patient monitors and includes interface devices, an alarm panel, and indicator panels. The design logic is based on the need for nursing personnel to also be alerted in the event of any abnormality associated with the patient monitors, the alarm panel itself, or with the interconnections. The system will also accommodate infusion pumps, respirators, or any other devices equipped with a remote alarm (nurse call) output.

Development of a high-precision continuous extracorporeal hemodiafiltration system.

A high-precision hemofiltration system appropriate for use in neonatal, pediatric, or adult patients has been developed. The system incorporates computer-monitored and -regulated pumps for control of blood, dialysate, and drain solutions and weighing scales for measurement of fluid infused into and removed from the patient. The overall accuracy of the fluid infusion and withdrawal is +/- 3.5 grams. The system incorporates four pressure transducers to monitor pressures. It includes alarm limits for pressure, solution volumes versus time, temperature, air leak, and blood detection in the drain effluent. The computer stops all pumps in alarm conditions. The system also can be easily adapted for other extracorporeal procedures such as hemofiltration, ultrafiltration, plasmapheresis, and extracorporeal membrane oxygenation.
