BEST WISHES!!!
Start with 5 ft = 50 kg
Then add 2 x the inches left over
Example: 5' 8'' = 50 kg + 8(2)
= 50kg + 16 = 66kg
This is quick and approximate math and its what's being taught in my Kettering book.
Absolutely. Thank you for sharing alternative ways to calculate IBW!
Wait this works for both male and female?
So this will be ± 2?
This was great! I’m RT that left the field for 10 years and now back again. This has been very helpful
thank you so much! I’m in RT school and I just found your channel and already I’ve gotten a lot of concepts cleared up. you’re making a real difference I hope you know that
You are so welcome! Best wishes in RT school. Glad you find the channel helpful. Thank you for watching and kindly commenting!
This teaching is so much easier to digest than even the Kettering lectures. 🙏🏾 thank you.
Thanks! Keeps me from always second guessing myself! Really easy to understand and follow! YOU ROCK!!!! 🤘🤘🤟
Thanks, Tonie! Never second guess yourself, but do, when in doubt, think through things twice. There's a difference. Thanks for watching!
Yo thank you so much for the help man you’re a blessing . A trick I do for the 6’0 + patients when trying to find IBW for example : if the male is 6’4 I just multiply the 4 by itself which gives me 16. If they are 6’5 I multiply the 5 by 5 which will give me 25. Etc etc you’ll always get the answer in the parenthesis.
You’ve made learning MV a breeze! The explanations make sense now!
Cool! Thanks for watching and commenting, Mayra!
I was just getting on here to see if you had a video on this AND here it is!!! 👌🏽👌🏽👌🏽 thank you!!
Cool! Thank you for checking in and watching!
I've been an RT for 2 years and I still go back and listen to your videos to refresh on things. Thank you for your content, I hope u keep putting out videos. I wish there was a way to show my support!
Your kind comment shows plenty of support! Thank you, Justin!
6 years and I still come back like I never left. Anesthesia school next so I gotta be on point with everything
This has been awesome thank you! Been on maternity leave and needed to brush up before heading back to work!
This is awesome! Congratulations on your little one. Get back at it (when you're ready) and go be great!
You are a savior mann....I have an exam tomorrow and I m binge watching your videos😂
thank you so much your method of explaining and formulas made it easy to understand and calcuate
Thank you so much for the simplicity of the concept.
You're very welcome! Thank you for watching!
Thank you for helping me refresh my formulas and calculations, I retired after 30 years and decided to return PRN during COVID, I wish you existed 33 years ago, school would've been so much easier! LOL!
Lol. Strong work returning to help out. I admire that. Thank you for watching and kindly commenting! I appreciate you.
Congratulations on your retirement Ms Robin you don't look a bit over 30 girl okay
This has helped so much!! Been looking for a review over this
Cool, Thomas. Glad you found us. Thanks for watching and commenting!
You are awesome, Thank you so much for helping me understand mechanical ventilation
Glad to help! Thank you for watching and kindly commenting!!!
Same question in my mind has been answered...thanks coach😊
Thank you so much. I am in my fourth semester and this video really helped me a lot
These videos are literally helping me so much I wish you could come be a speaker for my class my teacher figures out how to explain it us using all your videos
I’m watching your video in new year night 2023, my first video of the year
Thank You, These breakdowns are great.
Loving these videos
God bless you for saving a situation 🙏
Thank you for all of these videos! Very helpful for me as a recent grad. I think the reason why we start at PEEP of 2-6 is because when the patient is intubated, it takes off the normal physiologic PEEP which is around 2ish. Ive read it somewhere, but correct me if I'm wrong.
That's exactly the correct answer. Congratulations on recently graduating!!! Go be great!!!
You have been a tremendous help during my respiratory program. Can do a video on the oscillator and setting?
This video is awsome, great job.
Glad you liked it!
Good explanation, next video on indication and initial pressure-control settings.
Thanks and Regards.
Yes!!! I was struggling know this makes sense
Best teacher, thank you so much
Thank you so much for watching and kindly commenting! GO BE GREAT!
You are the man.
Very helpful, thank you!!
Do you have a video of what to do after setting initial vent settings after receiving abg results I struggle with this the most
Thank you this make a lot of sense 😊🙏
You're very welcome. Glad it helps! Thank you for watching and commenting!
Love your videos and love what you're doing with educating future Respiratory Therapists. One quick question, I know your channel is aimed towards students, but is there any way you could make a video for therapists who precept and things we can do better to be better preceptors? Also would love to hear input from current students as well. Thank you so much!
Hey Matthew! Thanks for the nice comment. And yes, I'll see what I can put together for preceptors. The fact you still watch, learn and grow as a practicing RRT, tells me that you're probably a damn good preceptor. Stay tuned!
Hey Matthew. Requested some insight from students today. So I'll be gathering that I'm the next few days for your video. Also, when you say being a "better preceptor", are you precepting students, new grads, or both?
@@RespiratoryCoach hey thank you so much, that means a lot! Any way I can contribute or help as well, let me know. I train both students and new hires, but I mainly precept students, which I really love to do. So any input from students is greatly appreciated!
“Shortcut”: IBW (kg)=50+(2x inches over 5’)
Then add a zero to end of kg (this is the max Vt)
Range: Then kg/2 = min Vt
Ex: I’m 5’7 sooooo 50+(2X7)=64kg
Add a zero- 640kg
640/2= 320kg
My mechanical vent range is 320-640
Learned this shortcut from Kettering and is a good “guesstimate” for Vt setting on vent..so far with all my practice test it’s been working.
Also, this is based on a 5-10 ml/kg range
Cool! Thanks for sharing!!!
Very useful sir
Me and my friends are currently studying for our Board Exam 🤣 and we’d do rationales together and some of our classmates would go “how did you guys come up with that???” And the 3 of us who’s watching your videos for help goes “oh, Respiratory Coach said it on one of his videos about mech vents” and they’d go “who????” And we’d send them your youtube link 😂 you’re such a great help! I think there are 5 or 6 of us who’s currently watching your videos to help us with our board exam review 😁👏🏻
I love it when we would agree on a subject and then we’d insert the phrase “This is all thanks to Respi Coach” ☺️😂
Lol...you're too kind. Glad the videos help.
@@RespiratoryCoach some update coach! We passed our RTLE!!! 2 of my friends were topnotchers and we watched your videos together!! THANK YOU!!!!!
great explanation sir , concept is crystal clear , thank you for the lecture sir , sir how do we calculate the IBW for a child , neonate , is there a difference sir, sir teach us about initial vent settings to a child ( paediatric) , neonate , sir teach us about neonate vent meathods , modes , settings ,
You are the best
Very informative sir...
Glad you think so, Akshay! Thanks for watching and commenting.
You explain very well. I wonder if you could do a video explaining co2 retainers, what their arterial blood looks like and what the chemoreceptors respond to.
Hi Nesssita! I'll work on that for you!!
Thank you so much
Other methods
Male 106 + 6(H-60)
Female 105 + 5(H-60)
Or
Male 50 + 2.3(H-60)
Female 45 × 2.3(H-60)
It’s such a shame that we cant claim your lectures for CEUs !!
Hi, Adrienne! Interesting thought. I might just have to look into this.
😊5😊44😅
In the new 2020 Lindsey Jones they're saying that female is 45.5 kg+(2.3*(height(n)-60))
Can you show me how to solve this 4'11
I'm really hoping someone can pls answer this within several hrs. Question: When setting up an aerosol face mask or ATM, AFT, etc....with a SVN inline..how would this be set up? Would I attach the Svn clear tubing to an O2 flowmeter or utilize the Med air..at 6-8 L/min? If I use an access O2 flowmeter how would this affect Fio2? I understand that w/COPD PT ..I would utilize the med air.. I hope this question makes sense the way I explained it. Thank you ahead of time.
Thanks coach
You are so welcome, Scaria! Thanks for watching!
Thanku so much i was so confused!! 😁🇿🇦
Hello, Kay. Glad it helped to clarify things! Thank you so much for watching and commenting!!!
Yes u did veryyyyyy well. Im still need to get the I:E ratio... i know you have a video but Im not getting it.🤯🥴
Thanks!
Hi dear! Can we use this formula RR X Vt X 6 for flow
Thank you
I love your videos! Would you mind doing one on Time Cycled, Volume Cycled, Pressure Cycled and Flow Cycled?
Absolutely, got in on the list. Thanks for watching and for the kind comment.
Here you go! czcams.com/video/wGb4qGmKRhI/video.html
How about adding dead space to initial vt, 400 initial VT minus dead space is less than 400 for an adult?!?.
Would you please offer a video about trigger setting on mechanical ventilation ;
Thank you....
Absolutely! Got it on the list! Stat tuned and thanks for watching.
This is great. I finally got the whole picture now. Do these formulas also apply to pediatrics and neonates? Thankyou so much for these videos.
Absolutely not! Neo/pedi is a whole another world. Working on getting my neo/pedi expert to join me for a video or 5. This applies to adults only. Thanks for watching, Kyle.
Neonates use their working weight to get ur ibw
@@twinstarr6635 Thank you for sharing this info.
Twin Starr how does that work with overweight kids?
What is the patient’s Vital Capacity expressed as ml/kg? thanks you are great teacher.
VC is expressed in either L or mL.
Where can i learn about deadspace ...what is that 😬
❤️❤️
Would you mind making a video on calculating a pts spontaneous Vt and spontaneous minute ventilation? Thank you, your videos have helped me so much
Absolutely, got it on the list.
Here you go...czcams.com/video/1Iai-VCGQbU/video.html
Hope it helps!
Could you explain dead space and the calculation more.
Also expand on peep and what that is
How do I see what other videos you have done as your video is excellent
Hello Pam. Below are two videos that might help. You can also use the search bar within my channel to find videos on other topics. Just use key words.
Deadspace - czcams.com/video/kAmpPaYW7oI/video.html
PEEP - czcams.com/video/nP9DDRdGmPw/video.html
Hope this helps. Thanks for watching and commenting.
So if it is 60" or less, you simply leave it at 106+6/2.2? Or 105+5/2.2? So the lower end is always fixed to either 50.9 or 50? Then of course multiply to get your volumes...
Or are you still subtracting - so, like for a 4'8" female - 105+5(56-60) --> 105+5(-4) --> 105+ -20 = 85 --> 85/2.2=38.6 --> so initial Vt would range from 231-308ml
Correct, Mike. Still subtract and apply the negative value.
@@RespiratoryCoach thank you!
I don't understand how you got 6X61 is 367 because I get 366 and 61X8 is 488 I don't understand how you got 490 Please advise
Should be noted that I:time should be adjusted for actual rate rather than set rate.
For sure! Thanks for that contribution to the discussion. And thanks for watching!
Can you please make video on ventilators modes.
Hi Maria. I have a few already, but planning for some new ones soon. Thanks for watching and commenting!
👏👏🇵🇭
What if person is less than 5 feet.
Very good explanation but this does not include the calculation of IBW that is under 5 FT
Thanks, yugioh! I'm not aware of a different formula for less than 5 ft. Same formula but the second part becomes negative and works down from 105 for female or down from 106 for male. 105+5(58-60) = 105+5(-2) = 105-10 = 95 pounds IBW for a 4'10" female.
What if he’s 6ft?
I would have to go back and watch the video, but if it's just talking about IBW, then you would calculate IBW based on 72 inches. 106 + 72 = 178 / 2.2 = 81 kg means we would target a tidal volume in the range of 486 - 648 mL.
IBW = 50kg + 2kg per inch over 5 feet
5’4” 50 + 8 = 58kg IBW
Thank you Davidson! Does it matter for male vs female? Seems like it would?
Respiratory Coach works for either. Used the formula on the helicopter. Scene flight and critical care transports. Using the 6-8 ml/kg IBW gives a good window to work with.
Respiratory, forgot to say but the original formula was 2.3kg instead of 2kg. But still works well.
@@davidclifton5033 Cool man! Thanks for the contribution to the channel. I appreciate you watching and commenting!
What about pt over 6 feet? Does this formula still works?
Sorry, I can't understand why so much initial precision, even requiring a calculator to obtain a value with decimals, if you end up multiplying by 6 or 8 to get the final value. This last calculation grossly modifies the previously obtained values.
Unfortunately in Saudi Arabia we use cm for hight so this video wasn’t useful but thank you anyway
