In my region we give 0.4mg ntg every 5 minutes as long as bp remains above 100 systolic. We can also add an inch of ntg paste as an alternative or in addition to ntg spray with the same bp requirements. Lasix is 40 mg or twice the Pt's single dose, up to 160 mg. We used to have morphine in the protcol but they took that out recently. I always thought the morpine really helped with the bad CHF'ers. We are now looking at adding C-PAP.
