Fig. 3. Example study with MATLAB software analysis. The top panel shows a representative planimetry plot showing diameter changes over time during the 3 different balloon positions at 30, 40, and 50 mL balloon inflation volumes. The bottom panel depicts volume and pressure changes over time. Note (in blue) the phasic pressure variations (oscillations every 3 seconds) throughout the study. The black line is a weighted pressure average which reduces phasic oscillations. Also note the distinct pressure decreases as the balloon position changes from the proximal position to the middle position, then to the distal position in each balloon volume inflation time period.
