Which hemodynamic parameters can be used to titrate positive pressure ventilation in preload dependent settings such as RV failure, cardiac tamponade, HOCM or hemodynamically significant PE?  

As this question alludes, the application of positive pressure ventilation influences cardiac hemodynamics. Key principles of these cardiopulmonary interactions are outlined nicely by Alviar and colleagues (1) in a well-done review. In contemplating this question, it is important to consider the sep...

Congratulations on an excellent question! Unfortunately, excellent questions do not always have equally excellent answers - and that is the case here, in my opinion. It is absolutely reasonable to assume that the institution and application of positive pressure ventilation (PPV) (whether invasive or...
