The STARLING CURVE :
- describes the relationship between the cardiac ventricle and its potential for ejectability of its volume.
- describes the status of the cardiac sarcomere.
pictured above : the basic / generic curve.
above : how to read : draw a line from the x-axis to the curve.
(more to follow at a later date).
follow the line up to the curve.
once you reach the curve, go directly (perpendicularly) left.
keep going till you hit the y-axis.
read the value on the y-axis (3L/min) – for this patient at this time at this current volume status.
back to the x-axis, start giving 1L of IVF (intravenous fluid) challenge.
based on the units on the x-axis, go to 1L of IVF moreso then before fluid challenge.
follow the line upward … till you hit the curve.
once you hit the curve, go directly (& perpendicularly) leftward.
read the new value on the y-axis … this is the new cardiac output after getting a 1L IVF challenge.
