How do you calculate IV concentration?
To calculate the millilitres/hour we first need to work out what dose is contained in one millilitre of the infusion dosage. We can do this by dividing the volume of the dosage by the weight of the medicine it contains. In this case 500ml/500mg = 1ml/mg.

How do you calculate IV fluids?
If you need to set this up on an IV infusion pump, use the formula, volume (mL) divided by time (min), multiplied by 60 min over 1 hour, this equals the IV flow rate in mL/hr. Using this formula, 100 mL divided by 30 min, times 60 min in 1 hr, equals 199.9, rounded to 200 mL/hr.
How is GTN infusion rate calculated?
The volume of each cannula was calculated (length multiplied by radius squared multiplied by Π) in mm3. This was then converted to millilitres (1 ml = 1 cm3 = 1000 mm3, therefore 1 mm3 = 0.001 ml). The rate of infusion in millilitres per hour was divided by 3600 to convert it to millilitres per second.
