Nursing Math: Dobutamine Titration & IV Pump

- Critical Care Drip Calculation Dobutamine Drip!
Dobutamine is used For the short-term inotropic treatment of low blood pressure
caused by:
congestive heart failure
septic shock
cardiogenic shock
or following cardiac surgery
I will note that In septic shock especially - fluid administration is the first treatment - but if that does not work a medication like dobutamine may be used.
Dobutamine = inotropic agent which increases myocardial contractility - specifically cardiac contractility - which in emergent situations will help increase cardiac output.
This is a Critical Care Medication because It must be titrated based on hemodynamic response,
Which include: blood pressure, urine output, heart rate, and (whenever possible) measurements of cardiac output like central venous pressure.
In this video you will hear me say that the the patient is unstable and the doctor has increased the rate. The increase would be based on these hemodynamic responses.

🎯 The correct order should be: *"5mcg/kg/min"* and it's not by *"hour".* Then her calculate could be right.
Yeah, I was wondering why I couldn’t use my own method. Way too. high
omg...i was killing myself trying to figure it out. i was like , something is wrong. that's it. thank you for clarify.
These drips are per minute, not hour.. do not watch this video it messes you up if you are studying for NCLEX
Now this video I can appreciate in comparison to the cardizem one. Great information and way of showing how to come up with the calculation & info needed. Thank you
Best demonstration, excellent work, thank you!
Yes!!! Please keep doing these videos!! So helpful!!!
Thank you! So helpful and interesting. I can't wait until I get into a nursing program (:
Why does this have 3 dislikes? She's trying to help us! Thanks Caroline!
🎯 Because. She commited a big error. Didn't notice it?
What’s the sense of converting to min(which I can’t understand if we are looking in per hour where is the given is already per hour)
I love your videos but the answer for this calculation would actually be 0.325 mL/hr if done correctly as follows:
Order of 5mcg/kg/hr can just be multiplied by the kg's of 65, so 5*65 = 325 so you're left with 325 mcg/hr.
Then you would make it look as follows:
mL 325mcg 250mL 1mg
___ = ________ x ________ x _______ = 0.325 mL/hr
hr hr 250mg 1000mcg
...The step you did that was incorrect was multiplying 5*65 and then by 60 minutes (there was no need to translate it into minutes, it was already in hours).
Love your videos but just wanted to make you aware of this!!
dose of dopamin and dobuatamine are in microgram /kg /min not per hour
THANK YOU. she already had 5mcg/Hr there was no need to further convert it
I definitely love you and your videos 😊
How do I know when to increase rate? Is there a protocol to tell me to I crease rate?
Love it 👌🏼
Where is the link to the dimensional analysis video you mentioned? Thanks in advance
Hi Heather! Here tis: ruclips.net/video/DsTg1CeWchc/видео.html

Why do you change the hour to minutes when finding out how many mcg/kg/hr? That's the part I'm not understanding.
The order should be 7mcg/kg/minute not per hour. Then,
65kg x 7mcg/kg/min x 60 min/hr = 27,300mcg/hr
The answer is 19.5ml/hr, correct? I replaced the first part with minute instead of hour and still got the same answer she got!!!
I am sorry but it must be per minute, not per hour. Hope you can fix the mistakes so that if someone who is not good at calculating can fix themselves. Anyway, thanks so much for making a very helpful video like this.
The order is 5mcg/kg/“HOUR” yet to you multiplied it with 60mins? Now that’s medication error.
Is the order 7mcg/kg/min? If it's 7mcg/kg/hr, what do you time 60 for?
I was wondering the same
It is suppose to be 7mcg/kg/minute. They are never 7mcg per kg per hour.. that is way too little.
Her very first line she wrote was wrong (should be O: 5 mcg / Kg / min the first time, and 7 mcg / Kg / min the second time, and 10 mcg / Kg / min the 3rd time), but everything else was right. To get it in terms of an hour (which is what the pump shows (mL/hr) she had to multiply by 60 because ((1/min)x(60min/1hr) = 60 notice how the minutes cancel out ... that's dimensional analysis). She must be doing it by muscle memory because she corrected for her mistake in the next 2 lines by 60 to get it in terms of an hour, again 3 different times, without giving any indication that she had made that error on the first line. It *is* a very bad habit ... the kind where in a passdown could result in dosing by 60 times too low by the next shift. She should annotate this is a mistake in this video.
Sorry but this video needs to be taken down because its more confusing than anything. Order is not even correct to begin with.
And then she proceeds to not even convert from what we have to the order. She skipped straight from mcg to ml. WAT lol
if you will be using these DO and numbers she'd given , it all came to me as :
on the first equation the answer is =0.325ml/hr
and the second equation comes to 0.455ml/hr
some thing is wrong with either the digits given , or her calculation .
im sure its the unit and computation that could be wrong here, coz it cant be this low..
well this is base on my computation using dimensional analysis ... been doing this for years .
but i could be wrong , please correct me if i am .
so as I tried to make some analytical testing here, I've got the answers to my question.
the doctors order should be
DO: 5mcg/kg/minute
DO: 7mcg/kg/minute
in order to derive to her answers of 19.5 mg/hr and 27.3 mg/hr
:) I hope I somehow help you guys
It's 0.325ml/min making it 19.5ml/hr. So she is right, her method is just long
There is a mistake in the order because she multiplies by 60. It is clear that the order was 5mcg/kg/min.
Yes 👍
She made me confused
Once multiple by 60..it is now mcg/kg/MINUTE...not hr. The pump set up in per min.
Same question
Confusing
Not subscribing when multiple times wrong calculation because the order was written down incorrectly
This video needs to be taken down or redone or someting
*Exactly*
I appreciate the use of the pump, but I think that you should review your own math problems. It can be confusing.
WRONG! It competitively
binds and stimulates α- and β-receptors (β1 > β2 > α), resulting in the major effects of increased contractility and heart rate, with mostly neutral effects on blood pressure.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. John 3:16 KJV, Ephesians 2:8-9, Jesus Christ is the only way...
I am sorry but it must be per minute, not per hour. Hope you can fix the mistakes so that if someone who is not good at calculating can fix themselves. Anyway, thanks so much for making a very helpful video like this.
I am sorry the first portion of the calculation is wrong. firstly, dobutamine dosage is only by mcg/kg/min not hr. secondly, if you already started with mcg/kg/hr, you dont need convert to min because you want to get to ml/hr. and the concentration of the available drug is basically 1mg/ml. the correct calculation should be: 5*65/1000=0.325ml/hr.
