In case of pul interstitial emphysema, there is hypercapnea, if I don't have high frequency......how can I manage.

In that case,try gentle ventilation with permissive hypercapnea,use min.PIP n PEEP,n. Low ti.avoid further VILI.n if single lung involved try selective single lung venti.or affected lung lobectomy at end.
