@10:33 : Don't you think the loop for 1-'restrictive' disorders should shift right (as RV decreases) and 2-'obstructive' disorders left (as TLC increases) ?
This is literally one of the best videos I have seen taught on this material. thank you so much for your help and clarity in understanding this stuff :)!!
Excellent clinical and physo explanation which I could not find on other resources. Formality is not an issue .You are clear and eloquent no matter if the audience is English first or second language .
thank you very much great efforts & beautiful logical presentation note : the flow loop for restrictive pattern ( minute 10 ) should be shifted to the right because there is reducing residual capacity *.*
Thanks so much for this video! At 12:09 when you give etiologies for the various upper airway obstruction patterns, as all 3 list "airway tumor", I would find it very helpful to have you elucidate the characteristics of the tumor in each scenario, that would cause it to elicit the type of pattern shown. Thank you. :)
Thanks for your fantasitic videos. My question is if FVC and VC are the same ( FVC is VC which is expired forcefully) why their amounts are different on the spirometry paper ?
I had one of these the LPN yes, LPN, gave me a complete PFT test incorrectly! did not tell me to take deep breath and blow hard...nor did I have a seal around the mouth piece which was the size of a galaxy cell phone, honestly .... the equipment is extremely old the techs will admit it....I am stuck with a diagnosis....it's like Hotel California!! they will not give me another test as the only pulmonologist in this area is egotistical, money hungry nightmare, that the hospital is afraid of due to his ethnicity, yes that's what I was given at a meeting with the CEO of the hospital and the board of directors. So thank you....for the graphics....I do believe, mine are normal looking. Thank with blessings.
Hello, what dosage should we give salbutamol aerosol for post dilation test? How many puffs? Is 4 puffs not dangerous? Usually obstructive patients get maximum 2 puffs at home for their Asthma treatment.
I cannot say with words how helpful is this video. Thank you so much!!!! (BTW How could I Reference this in a presentation? Found it really helpful and would like to show where I got some of the basic info you teach here
my resting oxygen drops down to 80 and I was diagnosed with plurisy/pneumonia at xmas 2017. I had an x-ray and the hospital said there was nothing wrong with me and sent me of saying good luck... I'm still not able to go to work 4.5 months later. I have chest and back pains still months later.
thanks for the video! just a quick note, you are pronouncing "expiratory" as "ex-pah-to-ry" instead of "ex-pI-Ra-to-ry" (you are missing a syllable). People do this often with respiratory and incorrectly say "res-pah-to-ry" instead of "res-pir-a-to-ry"
Appreciate the point, however, and maybe this is just us crazy laid-back Californians, but I actually find ex-pah-to-ry to be the more common pronunciation among my peers - though this is not to say that it's the "correct" pronunciation per se.
I just took my first PFT today for a job. I was confused why I had to exhale for six seconds when it felt like I emptied my lungs after just a few seconds. The last few seconds were discomforting and painful. I'm pretty sure nothing came out the last few seconds. Is it possible to exhale the lungs in a few seconds and then just hold that position for the last few seconds and still come out with an acceptable reading?
+Bryan Gaston I don't give out the PowerPoint files any more because I ran into too many people blatantly plagiarizing them. However, if you send me an email, I can send pdf versions of the videos (essentially high-res screen shots of each slide, stitched together in one document)
@@StrongMed Hi, would you be able to send me the PowerPoint files by any chance? I'm currently writing them all by hand and this material is very helpful!
Thank you very much for very clear and very professional explanation. Is there any difference regarding technics of testing depending on type of spirometer device?
I'm sure there are differences, but unfortunately, I know little about the specific technical aspects of actually performing the tests themselves beyond what is presented in the videos. A respiratory therapist would be a better resource for that information than I.
Akhmetzhan Sugraliyev I'm so sorry, just seeing this follow-up response now! I have no idea if this makes a difference, but I avoid posting my email address directly on TH-cam comments out of concern for increasing spam. Instead, my email is listed here: med.stanford.edu/profiles/eric-strong
Hello, my pulmonologist won’t call to tell me about my tests. I get the worst cough at times. I have a nebulizer and Advair generic. I have no plan or diagnosis. Why would I go take tests if he won’t explain them? I explained my view before last week’s test, but I think that he was writing his grocery list.
John Michael, thanks for the message. I go back and forth with myself regarding the level of formality in these videos. On one hand, I totally get that a lot of viewers may find it easier to pay attention and connect with the video if the overall tone and style is more similar to Khan Academy, or on the other extreme from me, Crash Course. However, a significant number of my subscribers are from places where English is not their first language. I've always been concerned that speaking too rapidly, and adding more colloquialism and asides might make it more challenging for them to follow. Also, one of my goals with these videos has evolved into a desire to post the didactics of an entire medical school curriculum (yes, I realize that is insanely ambitious), and thus, this is meant to replace an in-class lecture. The problem with less formal approaches to complex material is that it risks not being as comprehensive as it needs to be in order to fulfill this goal. But I do sincerely appreciate your suggestion!
Errata: @1:52, "functional RESERVE capacity" should be instead labeled "functional RESIDUAL capacity"
@10:33 : Don't you think the loop for 1-'restrictive' disorders should shift right (as RV decreases) and 2-'obstructive' disorders left (as TLC increases) ?
This is the most comprehensive and complete PFTs lecture for students !
I must say... your series on PFT's is probably one of the best out there...you have elucidated it so well. Kudos.
Doctor Eric,
I can safely say that you are one of the best teacher I ever met. Thank you for being an amazing.
u said this 5 years agoooooo? wow
This is literally one of the best videos I have seen taught on this material. thank you so much for your help and clarity in understanding this stuff :)!!
wow. its the first time in my life that I actually understand this. I'm full of gratitude:)
I really loved the way you slowly incorporated each line and plot point rather than showing an overcrowded picture and graph
Excellent clinical and physo explanation which I could not find on other resources. Formality is not an issue .You are clear and eloquent no matter if the audience is English first or second language .
When i saw This for the first time it was like reading chinese .... But when i read it again and again it became easy :) Thanks a lot DOCTOR
Thank you Dr Strong. I seem to get from second listening , and it is wonderful that you point out Gold system lack predictive value for individual.
Just started learning this in class last week with the spirogram..I finally understand this :) thanks.
thank you very much
great efforts & beautiful logical presentation
note : the flow loop for restrictive pattern ( minute 10 ) should be shifted to the right
because there is reducing residual capacity *.*
Lol Don Draper as the patient with abnormal PFT's thanks to his smoking history. Lovely touch to an amazing channel.

7:17 FEV1/FVC ratio: decr'd in obstructive & NORMAL TO INCR'D in RESTRICTIVE dz 9:34 6 Flow Volume Loop patterns
Very high quality teaching. Tons of thanks!
Great videos. I use them to understand the basic concepts found within our lectures.
very informative and usefull ,thank you very much
dr.Ali attaee from Iraq
So well explained and such a calming voice. I bet he's not hard on the eyes either!
Wow beautifully taught video. Thank you for your wisdom!
Dr.stong, thanks a lot! Around 09:40，"... and flow versus time on the bottom", I guess it might should be "...flow versus volume on the bottom" ?
i have a test tomorrow. i hope this will help! thanks!
Wow, so informative. Thank you so much
Thanks for your fantasitic videos.
My question is if FVC and VC are the same ( FVC is VC which is expired forcefully) why their amounts are different on the spirometry paper ?
Thank you sir..
But at 09:38 --- will it not be 'flow vs volume' ??
Your explanation is excellent
Very very helpful! Makes it quite clear: thank you for the video.

obtain a copy of your test and file a lawsuit. :)
Shouldn't there be "flow versus volume" at the bottom graph at 9:35?
I loved the Bach intro!
Thank u so much that was actually helpful in understanding the basics
Absolutely brilliant

Your presentation was very helpful to understand PFT. I would aprreciate if you provided me with some referneces to this content.Thank you
what is the bronchodilator dosage for after dilation test ?how many puffs salbutamol to give?
Спасибо огромное за качественное объяснение сложных моментов!👍 Рисунки понятные!
When they say "reversible obstruction" is it FEV1/FVC from 0.7, or FEV1 from 80%?
Best video ever
Thank you so much 👍👍👍
Excellent lesson! Thank you

***** get off his back
How does spirometry measure the flow-volume loop if it does not measure the residual volume? I don't understand that part
amazing piano into/outroduction. I would love to know what that is!
It's Bach: Prelude in G major (BWV 860). (I know the music credit at the end is incorrect...)
Awesome! Thank you, thank you, thank you!
excellent teaching thank you
awesome video! I think you meant vocal cord dysfunction and not vocal cord paralysis
thank you so much... from egyptian med student
Thanx 👍 u made it so clear 😊

This is great information however I have a delima , my spirometer only measures FEV1 and PEFR. how can I calculate my FVC??? Please Help :(
I like it but in our country online
is so interrupted.
Nice to give time .
Exceptional Elucidation
Muchas gracias. Muy bueno.
Sir how to flow the air in spirometer like ballon or any other method
I'm really sorry but I don't understand the question.
what is the piano piece at the end of this?
