The study of hemodynamics in critical patients under intensive care unit conditions

Studies of hemodynamics in critical patients under intensive care unit conditions have been a very difficult task until now [1]. There are a number of reasons for that. No instruments capable of noninvasively recording data on hemodynamics and metabolism, as well as the cardiovascular system performance, could be used. Of course it is reasonable that, according to the relevant methodology, all the data should be recorded on the 'here-and-now' basis, in real time, to enable rapid decision-making in order to save the patient's life.
