Any literature advising use or contraindication of HFVO in acute pulmonary hemorrhage? Would persistent respiratory acidosis be an indication to discontinue HFVO?

I don't remember about contraindication (I didn't check new literature)...usually HFOV (and its high maps) helps in a pulmonary hemorrhage.

Usually I treat a persistent respiratory acidosis with HFOV, of course it depends on etiopathogenesis of acidosis and if patient needs ventilatory support or not...

 

....but I suppose that your question is more complicated than my answers...
