Experience of using analysis methods of heart rate variability in anesthesiology practice

This paper aims to develop a means to estimate the practical efficiency of heart rate variability (HRV) analysis in the perioperative period to help define the adequacy of anesthesia. By monitoring the patient´s status with the help of the indicated agents, the adequacy of anesthesia can be estimated and early diagnostics of complications originating during an anesthesia can be provided. For the anesthesiologist, it gives possibility to appreciate the various pathologies and possibility to take action for accident prevention. It is necessary to notice that in perioperative period the real-time usage of this calculation method requires control over sensors quality and level of noise. The fact is that the high level of industrial and surgery noises can decrease all advantages of this method.
