Excellent #KIDNEYcon session by @criticalbeansmd about MAP and other perfusion pressures.
👉 Blood pressure is not the same as blood FLOW.
Under normal conditions, pulse pressure wave precedes flow volume wave. #KIDNEYcon
In sepsis, vasodilation can lead to decreased speed of pressure wave and increased speed of flow wave.
#KIDNEYcon
Hence increasing MAP as isolated target, may not be reliable index of flow 👉 organ perfusion.

But don't forget about the venous pressure and consequences of volume overload.

A state often misinterpreted as 'total body overloaded, but intravascular depleted' ... resulting in more volume administered 🚫
