The purpose of this study is to compare the values of Surgical Pleth Index (SPI) and Nociception Level Index (NOL) measured simultaneously during cardiac surgery.
Participants are given oral and written information about the course of the trial, associated risks and benefits and about the handling of the personal data on the day before the surgery by one of the investigators. Participants are also given written information about patient's rights and insurance, the aim of the trial and its course. 40 adult cardiac surgery patients will be recruited for the study. NOL and SPI values will be measured during the cardiac surgery procedure. All patients receive oral premedication and standardized anesthesia.

SPI values measured at several timepoints during cardiac surgery
SPI (Surgical Pleth Index) - index measuring nociceptive response based on pulse and pulse amplitude.
Time frame: Values are measured during the course of the cardiac surgery procedure
NOL values measured at several timepoints during cardiac surgery
NOL (Nociception Level Index) - nociception index based on heart rate and its changes, pulse wave amplitude, skin impedance and its changes, temperature and their variations
Time frame: Values are measured during the course of the cardiac surgery procedure
