Invasive and Ultrasound Based Monitoring of the Intracranial Pressure in an Experimental Model of Epidural Hematoma Progressing towards Brain Tamponade on Rabbits
Figure 7
(a) Optic nerve sheath diameter (ONSD) in mm plotted versus the ICP (mm Hg); the scatter plot displays a positive exponential relation (slightly different compared to the PI plot) between the two parameters rather than an exact linear relation. (b) Regression analysis model: the “dots” represent the actual measured values, while the blue line in the middle represents the estimated values by the model and the dashed lines represent 95% confidence intervals. (c) Goodness of fit for the model-driven prediction equation calculating the proximity of the predicted values (dots) to the actual measured values (dashed blue line).
