Figure 3From: Quantification of compensatory processes of postnatal hypoxia in newborn piglets applying short-term nonlinear dynamics analysis Illustration of SPPA indices for cardiov ascular interaction. Graphical representation of indices from segmented Poincaré plot analysis (SPPA) for cardiovascular (BBI and DIA) interaction from one piglet's normoxia phase. Numbered column and row indices are indicated while the width is determined by SD1 (row) and SD2 (column) calculated by standard Poincaré plot analysis (PPA).Back to article page
