What is the formula for IV drug calculation?
and the following formulae can be useful:
VOLUME (mL) =RATE (mL/h) x TIME (h) RATE = VOLUME REQUIRED = x. DRIP RATE (DPM) = 150/0/mL x 20/ VOLUME REQUIRED = 750. TIME = 2000. 160mL. 160mL. There is 10 mg morphine in each stock ampoule, so you need 3 stock ampoules (3x10 mg = 30 mg) to get the required 30 mg morphine. 27mL.Most macro sets are either 10, 15 or 20 drops to make 1 mL.
The other drip set is a micro set, and it either takes 45 or 60 drops to make 1 mL.
When giving most medications via continuous infusion, micro drip sets are the preferred method.
How do you calculate IV solution?
The formula for calculating the IV drip rate is… total volume (in mL) divided by time (in minutes), multiplied by the drop factor (in gtt/mL), which equals the IV drip rate in gtt/min.
Let's try an example.
