Increasing numbers of monitors at the anaesthesiologist's workplace, providing more than 20 different parameters of the patient's condition, have already made it impossible to record all the values in a handwritten form. Consequently, this most common method of record-keeping must be incomplete and inaccurate. In recent years computerised data-acquisition systems have been introduced into clinical practice in order to produce more reliable records. ⋯ Based on more than 30,000 values for each parameter, the incidence of artifacts was 3%-7%. However, only 0.1%-0.5% of the artifacts could not be eliminated by the filter. The method described here provided acceptable graphic printouts of the most important haemodynamic parameters (Figs. 1b and 2b) and would also be suitable to serve as an input filter for automatically running anaesthesia data-examination processes, which are currently being developed in our clinic.
