Estimation of the depth of anaesthesia from interacting physiological oscillators

Nowadays, physiological monitoring is imperative for the safety of medical operations. However, systems which monitor the depth of anaesthesia are still far from reliable, such that still some patients may experience the trauma of remaining conscious under ...

Consideration of the effect of the anesthesia in the thalamocortical assemblies

Martin Hasler, Kumiko Oshima, Borja Ibarz Gabardos

Despite intensive research efforts, the effects of anesthesia on brain physiology and function have not been satisfactorily explained yet. Nevertheless, from what has been discovered up to now, we can attribute the effect of the anesthetics to changes in c ...

State Change Detection Using Multivariate Synchronization Measure from Physiological Signals

Martin Hasler, Cristian Carmeli, Kumiko Oshima

The cardiovascular system can be macro-modelled as a collection of coupled oscillators. Recently, the use of mutual couplings of these oscillators to characterize the state of the system during anaesthesia has been proposed. Assuming that the synchronizati ...
