Promising Anesthesia Monitoring System

An anesthesia monitoring system, PSA 4000, that serves as an early warning device enabling an anesthesiologist to monitor and manage a patient's level of consciousness during surgery was found promising by investigators in a clinical trial.

The study was conducted during cardiac surgery at the German Heart Institute in Berlin (Germany), which has extensive experience in consciousness monitoring. The investigators concluded that even "in the stressful surrounding of a cardiac theater, it (the PSA 4000) represents a promising monitor for depth of sedation of the second generation.” Following its evaluation, the institute elected to continue using the PSA 4000. The study will be presented at the 5th International Conference on Memory, Awareness and Consciousness in New York (NY, USA) in June.

The PSA 4000, called the Patient State Analyzer, is the product of Physiometrix Inc. (North Billerica, MA, USA). The system incorporates sophisticated signal-processing electronics and proprietary software. The company, which has received the CE Mark of approval and also ISO 9001 certification, believes the PSA 4000 has the potential to enhance patient care, improve recovery times, and save lives in hospitals around the world.
