44#(20kg) 5 mcg * 20 kg = 100 mcg per min. and x 60 for hours = 6,000 mcg needed per hour. If strength on hand is 0.2 milligrams per mL or in micrograms: 200 mcg/mL And you use the “dose needed divided by dose on hand” rule: 6000 (needed) divided by 200 (on hand) ..the answer 30 mL/hr. 30 mLs needed every hour to deliver the 6,000 mcg per hour. or in minutes, divide by 60: (6000/60). So every minute, at this rate, you’d be delivering the 100 mcg per minute we need i.e. the mcg/kg/min ordered. The answer is most definitely 30mL/hr. Not 1.8
I got the answer 30mL/hr without using 16.67 by taking into account the concentration which is 0.2 mg/mL, and a few conversions to cancel the other units. But I guess your way is much faster since conversion is no longer needed.
Hey I want to ask something if the dose rate is given in total dose for example in avilin (pheneramine maleate) in my drug compile book the drug dose is written as total dose in ML - 0.5-1ml but this drug has a concentration of 1ml contain 22.7 mg How can I know for which body weight I need to give within this range of 0.5-1ml
For this formula method to work, R has to be ml/hr and the other units have tobe as shown in the video. This is because of the units on 16.67 as discussed in the comments below. Several us also got 30 ml/hr as you did. She didn’t need to convert mg to mcg. The 16.67 mcg hr/mg min took care of that already.
1000 mcg/mg * 1 hr / 60 min. =16.67 mcg hr / mg min. Not sure we needed to do the 200 mg to 200000 mcg conversion. The 16.67 works if M W D V R are in the exact units shown in the video. ((5mcg/kg min)* 20 kg * 1000 ml) // (200 mg * (16.67 mcg hr/mg min)) = 30 ml/ hr or 0.5 ml/min say * 60 gtt/ml = 30 gtt/min or 1gtt every 2 sec. If the drug is a liquid, say 200 ml, then we would have to remove 200 ml of LRS to make room for the drug to be added to the 1 liter bag.
Woop woop, just finished the video. 1.8 mL/hr? That seems too low. If you don't convert the mg to mcg, you'll get 30 mL/hr. Which seems more appropriate.
Thank you 🤗🤗🤗
is your formula sheet posted to the public some where?
Top explanation
44#(20kg)
5 mcg * 20 kg = 100 mcg per min. and x 60 for hours =
6,000 mcg needed per hour.
If strength on hand is 0.2 milligrams per mL or in micrograms: 200 mcg/mL
And you use the “dose needed divided by dose on hand” rule:
6000 (needed) divided by 200 (on hand) ..the answer 30 mL/hr.
30 mLs needed every hour to deliver the 6,000 mcg per hour.
or in minutes, divide by 60: (6000/60). So every minute, at this rate, you’d be delivering the 100 mcg per minute we need i.e. the mcg/kg/min ordered.
The answer is most definitely 30mL/hr.
Not 1.8

Please show how to find "M" Thank you!
R has to be in ml/kg/hr, surely? So that last bit equivalent to 30 ml/hr?

Where did the 16.67 come from?
did you ever find an answer for where 16.67 comes from?
1000 mcg/mg * 1 hr / 60 min. =16.67 mcg hr / mg min. Not sure we needed to do the 200 mg to 200000 mcg conversion. The 16.67 works if M W D V R are in the exact units shown in the video.

From the hell

1,8 ml/h. Absolutely wrong. It will take 555 hours to drip 1.000 ml. Poor patient would die before the end of the drip. 30ml/h
Anyone needs formule to calculate drugs.
