Monitoring Capabilities of PulmoVista 500
时间窗: Day 1
The cross-correlation between the volume curve of the ventilator and the global impedance curve of PulmoVista 500 was expressed by the cross-correlation coefficient R. The cross-correlation coefficient is a measure to quantify the relationship between the volume curve and the EIT curve. The correlation coefficient R can assume values between \[-1, 1\] to describe the relationship between the two curves, as is usual for a correlation. To calculate the correlation coefficient, a phase shift between the two curves was taken into account, so the cross-correlation between them was calculated. The phase shift or delay occurs when the signal from the fan is transmitted to the PulmoVista500. The cross-correlation coefficient is determined by calculating the correlation coefficient for the curves within a narrow range of Lags(-15 to 15 ) for each pair of curves and using the maximum value as the value of correlation coefficient (therefore it is called cross-correlation coefficient)
