ICU Physiology in 1000 Words: The Mean Systemic Filling Pressure – Part 2
www.pulmccm.org
Jon-Emile S. Kenny MD [@heart_lung] Briefly, part 1 of this reflection on the mean systemic filling pressure [Pmsf] considered an analogy for volume status as the vastness of an ocean beyond the hull of a leaking ship; I argue that looking only inside the hull of the ship cannot tell you the volume of the ocean – just as an echocardiographic volume assessment of the IVC or ventricle cannot establish the blood volume of a patient. Thus, an objective measure of volume status is described – the mean systemic filling pressure. Yet, like any pressure surrogate, relation to volume is complicated by the properties of the container in which the volume resides [i.e. the compliance of the chamber].
