WebMar 15, 2024 · Three concepts important in understanding the haemodynamic effects of PPV are: (i) Changes in intrathoracic pressure created by ventilation are transmitted to the heart, pericardium, intrathoracic arteries and veins. PEEP and pressure greater than PEEP impose supra-atmospheric pressures on these structures throughout the respiratory cycle. WebNote: these criteria apply to any technology using SVV/PPV to guide fluid management. Modified from Hofer and Cannesson. Inspiration during mechanical positive pressure ventilation results in increased intrathoracic pressure and a reduced venous return. Preload decreases, followed by stroke volume (SV) and pulse pressure (PP) once the blood ...
