Interactive computer program for the analysis of cardiovascular polysomnographic recordings

A computer program for the analysis of blood pressure, heart rate, oxygen saturation and some other polysomnographic signals is presented. The program analyzes the signals, digitized by using a 100 Hz sampling frequency, in one second resolution. The analysis and calibration periods can be entered to the program by pointing at the appropriate positions of the displayed signal with a mouse. As analysis results the program can produce statistical tables or graphical representations of the measured variables as a function of time. The program can be used in routine polysomnographic cardiovascular analysis and due to its flexibility also in experimental studies.
