Critical incidents can be occurred during anesthesia which may lead to death. These events can be detected using pulse oximeter; an instrument that produces photoplethysmogram, a signal represents volumetric measurement of an organ. During anesthesia, heart rate is commonly measured using photoplethysmogram. In this study, two different methods of measuring heart rate from photoplethysmogram were...
This paper presents a novel method in determining the respiratory rate from the photoplethysmogram signal of anaesthetic patients. The respiratory rate is important to be monitored when the patient is in anaesthesia state since the patient loss all sensations during this state. This study compares two methods of determining respiratory rate; peak detection and Fast Fourier Transform. The methods were...
