Autor: S. Mustola, T. Parkkari, K. Uutela, M. Huiku, M. Kymäläinen, J. Toivonen

Publikováno v: Anesthesiology Research and Practice, Vol 2010 (2010)

The performance of recently introduced Surgical Stress Index (SSI), based on heart rate and photoplethysmography, was estimated during sevoflurane-fentanyl and isoflurane-fentanyl anesthesia during surgical procedures. Forty ASA I–III patients were

Surgical stress index as a measure of nociception/antinociception balance during general anesthesia

Autor: K. Uutela, Johanna Wennervirta, Markku Hynynen, Anna-Maria Koivusalo, M. Huiku, Anne Vakkuri

Publikováno v: Acta Anaesthesiologica Scandinavica. 52:1038-1045

Background: No validated monitoring method is available for evaluating the nociception/antinociception balance. We assessed the surgical stress index (SSI), computed from finger photoplethysmographic waveform amplitudes and pulse-to-pulse intervals,

Comparison of skin conductance with entropy during intubation, tetanic stimulation and emergence from general anaesthesia

Autor: Johan Raeder, Hanne Storm, A. C. Gjerstad, R. Hagen, Erik Qvigstad, M. Huiku

Publikováno v: Acta Anaesthesiologica Scandinavica. 51:8-15

Background: The number of skin conductance fluctuations (NSCF) expresses sympathetic skin nerve activity. The response entropy (RE) measures electromyographic and electroencephalographic activity in the forehead. The state entropy (SE) measures mainl

Skin conductance or entropy for detection of non-noxious stimulation during different clinical levels of sedation

Autor: M. Huiku, R. Hagen, Hanne Storm, Johan Raeder, A. C. Gjerstad, Erik Qvigstad

Publikováno v: Acta Anaesthesiologica Scandinavica. 51:1-7

Background: State entropy (SE) measures electroencephalographic signals, whereas response entropy (RE) also includes frontal electromyographic activity. In the presence of electromyographic activity, the RE index is larger than the SE index, the diff

Publikováno v: Proceedings MEMS 98. IEEE. Eleventh Annual International Workshop on Micro Electro Mechanical Systems. An Investigation of Micro Structures, Sensors, Actuators, Machines and Systems (Cat. No.98CH36176).

For the first time a silicon IR-source and CO/sub 2/-chamber system for measurement of CO/sub 2/ concentration is presented. This new miniaturized infrared sensor is specially designed for the measurement of respiratory gases present in patient airwa
