Abstract
In the anesthetic management of critically ill patients, sequential and invasive monitoring system particulary for hemodynamic change of the patients are exceedingly needed and the monitoring equipments will require to maintain an electrical safety for the patients and to provide the definitely stable and accurate information of hemodynamic variables during surgery.
Therefore, we have studied about the electrical safety and clinical applicability of the fiber-optic electrocardio-graphy and blood pressure measuring system, and the following results were obtained;
1. It has been recognized that the fiber-optic method yields a high degree of an electrical isolation effect from the electromagnetic disturbances associated with use of electrosurgical unit.
2. It has been confirmed that this method are extremely useful for the electromechanical analysis of the sequential changes of the extremely amplified P-wave and right atrial pressure waves which were obtained during surgery.
