How do you calculate flow rate in nursing?
How do you calculate flow rate in nursing?
To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.
How is percentage calculated in nursing?
Strengths and concentrations
- % w/v = percentage weight of a substance by volume measured in grams in 100 millilitres.
- % w/w = percentage weight of a substance by weight measured in grams in 100 grams.
- % v/v = percentage volume of a substance by volume measured in millilitres in 100 millilitres.
How many drops is 100 mL per hour?
Reference Chart of Drops per Minute

| 20 | 100 | |
|---|---|---|
| 10 DROP/ML | 3 | 16 |
| 15 DROP/ML | 5 | 25 |
| 20 DROP/ML | 6 | 32 |
How does a nurse do titration in a hospital?
During an emergency, nurses can quickly locate a specific medication infusion to discontinue or check if infusing in a patent line. Although nurses may administer vasoactive medications in numerous hospital areas, the titration of these drugs is usually a criterion for intensive care admission.
How to calculate IV titration in mL / hr?
yExample 1 To lower BP, nitroprusside in dextrose 5% in water is to be titrated 15 – 200 mcg per minute. The IV solution was prepared by adding 50 mg of nitroprusside to dextrose 5% in water. The final solution contains a total volume of 250 ml. You should infuse the IV solution at a rate of ___ to ___ ml per hour.
How to calculate the infusion rate for a patient?
First you need to convert the mg per kg into total mg by multiplying it by the patient’s weight. So for a person who weighs 70kg, 0.5mg per kg is the same as 35mg. Once you have calculated this, the infusion rate can be worked out as in the Type B calculations. At what rate (ml/hr) do you set the pump?
How often should a nurse do the dosage calculation?
Even with the programmable I.V. pumps used in many clinical settings, it’s advisable for the nurse to verify the correct dosage by calculation once during the shift; more often if a medication is being titrated or changed.
