How do you set up pulse pressure variation (PPV) on the monitor? This, of course, requires an arterial line.
Here, @lillieannamd #CleClinicRespiratory shows us how it's done, quickly, on a Phillips monitor. After, we'll talk about uses wrt preload responsiveness... #tweetorial

PPV leverages the changes in preload owing to mechanical ventilation, effectively testing where the pt is on the starling curve. A positive response (threshold 12%) suggests they are on a dynamic portion of the curve. 
There are key assumptions which must be met for this to be valid. Namely:
(1) Patient must be PASSIVELY mechanically ventilated
(2) In sinus rhythm
(3) Tidal volume 8-10 ml/kg.
