My desired wt is 60kg/
concentration Remember to multiply concentration by 1000, measurements must be the same |
|
D/H (Q)= R

|
How do you calculate flow rates for manually regulated IV in gtts/min?
|
V/T (C)=R
C=Conversion factor (gtt factor) V=Volume R= Rate |
|
Solve for gtt/min
|
ml/ h (gtt facto r constant)= gtt/hr
Volume=ml C= gtt factor) time=hour Don't forget to convert hrs to min if question asks for gtts/ min |
|
