1/4 Mean systemic filling pressure (MSFP) refers to the pressure in the venous system that drives blood flow to the right atrium. Think of it as being equivalent to right atrial preload x.com
2/4 MSFP is affected by the volume of blood within the veins AND the compliance of those veins. This is important because we often think of “increase preload” = “give IVF” x.com
3/4 The other way to achieve this is to simply give a vasopressor. This decreases venous compliance and leads to a higher MSFP. This is key in patients who have low MSFP from systemic vasodilation rather than volume loss and is a way to avoid flooding your patients with ++ IVF x.com
