Pathophysiology of COPD 

I’m currently a nursing student and one of my module tutors has suggested watching all your pathophysiology videos. I have now managed to watch most them and I’m delighted to say that you are doing a wonderful job 👍! Thank you so much for all your help and for taking the time to explain these diseases!

Returning to practice and reviewing the chronic diseases-thank-you for the clarity. Matching clinic symptoms to the pathological process is YOUR talent. Very appreciated!

I have copd, and I wondered if there was a direct relationship between the results of a spirometer test, and how breathless you are on your worst days. Brilliantly explained video, thank you so much.

Absolutely love how you bring this down to earth and make the explanations so simple. Watch these over and over!!

Am studying for my oncology nurse certification test, and am finding your videos to be a great addition/ refresher for pathophysiology. Thanks for making this as painless as possible!

As a Respiratory Therapy Student I appreciated the explanation and illustration clarity. The presentation was direct, succinct, well spoken and very digestable for students at many levels. THANK YOU! Alan D. Bosch, RT Student TTC, MUSC Respiratory Dept.

I've spent 4 months in my second to last nursing semester and you explained COPD more clearly in the first 14 minutes than my instructors have all semester.

I'm a nursing student and this was very helpful. I always need to wrap my brain around the process in order to remember things and you present the process very well.

I been living with Asthma COPD for 7 years, its very similar to the one called Enphazema and bronchitis, but COPD basically means lung damage, and if you have Asthma it goes through all the same stages, it is really a delight that this knowledge and information is out here and especially on RU-vid. Thanks!

in my second year of RN school. I wouldn't have made it this far without your videos. I love, love everything about them. Often I find myself passing exams and HESI tests with simply watching your videos and making notes right along with you. Please please don't stop posting them. Sincerely, O heck... my name is Teresa!!!!

Thank you so much for explaining this. My partial diagnosis is COPD, yet I find that in the summer, with sufficient moderate exercise my symptoms largely disappear. I use Albuterole and Asmanex. The symptoms I have do not include throat constriction, just excessive coughing. Now I understand the etiology of my condition much better.

Hi, thanks for helping me prepare for my Pathophysiology of Disease finals. I'm studying for a BSc in Physical Activity and Health in Scotland, and your videos are a huge help in understanding this complex subject. Thanks very much.

Your lectures are fantastic, thank you for doing them. I have pathophysiology online this semester and my teacher doesn't offer audio for studying. Your lectures have really helped my understanding of the material.

I have been struggling to understand the pathophysiology of COPD, it just wouldn't sick in. I finally get it, thank-you so much.

Thank you so much for these videos. They're helping me get thru nursing school. The pace and clarity of your explanations are so helpful.

NP student here. I have learned about COPD many times but you hit on some points that never seems to click. Thank you!

Absolutely brilliant Andrew, I am a nusing student in Western Australia who was struggling to understand COPD, but wow ! you have hit the nail right on the head. Many thanks for this production.

Thank you for this. I'm also a nursing student trying to get a better understanding and you've done a better job than all the vague answers my instructors have given.

Top man …… such a great explanation……… I have sat through class trying to understand spirometry and PFT's ………now I get it

Excellent lecture! I work in biologics R&D, in part with pulmonary therapeutics. This video is one of the best overviews of COPD I've come across. Can't wait to view the rest of your contributions at youtube!

Andrew just wanted to give kudos on your willingness to post these lectures, donation of your time, and utilization of technology in furthering the understanding of pathophysiology. Speaking for myself I have really enjoyed your teaching style and look forward to watching more from you, thanks and all the best. ~Zachary

I am a visual learner and find your videos so helpful in understanding these complex diseases and their associated patho. Thank you for the great tools :)

Thank you for helping me understand my disease more,i am a 24 year old that got diagnosed with COPD 4 months ago,my life has made a 360 turn,its been hard,especially knowing that my case is a 3 in 100,i have AAT deficiency.

Sir, thank you. You have clarified for me so much I didn't understand before watching your video. I have COPD, & it really helps me to understand what's happening.

Short and to the point many thanks, I am an anesthetist and preparing for the oral part of my exam, your lecture is very helpful

I am currently studying an MSc in physiotherapy and find your videos very useful, thank you!

You do such a great job at explaining how and why things work the way they do. When I understand it like this, I'm much more likely to be able to retain in long term. Thanks so much for posting it!

thanks andrew. i ami aclinical pulmonogist since 25 years. i am now teaching at mauritius univ.your approach is clear and i have adopted your style.thank you

Awesome video! I am a second semester ADN student and we are currently studying oxygenation and related diseases and this really helped. I plan to share it with my classmate. Thanks so much! Look forward to more of your videos!

Dear Andrew Wolf, you are awesome. I am preparing for my test and ever since i started watching your videos I know that i really understand well. Just a suggestion there are a number of diseases with most prevalence but I cant find them in your channel. overall Great

Thank you for taking the time to make this video and many others, it has helped me understand COPD much more clearly

Best vid in youtube about the pathophysiology of COPD. Thank you for sharing.

Big thank you Andrew ..I have a sister with COPD and you have explained this progressive illness very clearly.

Great summary! I am a nursing instructor and this is a great resource for me to recommend to students! Thank you!

Excellent work. The cilia is definitely key and most forget to mention that even focusing on the lung function thereby showing their lean towards pharmacology technology rather than biological function. Except that they also know some people go bald, sweat less or not at all, loose cilia, and other factors such as Alpha-1 genetically are related as well it seems like. I'm not a Dr. but everyone I know that has has COPD has a complex mixture of many of these factors indicating a definite genetic predisposition. Thank you for that word about Fibrosis too.

i work as a medic and your videos were very informative.

You are the reason I will pass my national exam. Thank you!!

Extremely helpful and easy to understand! I am an NP student and your video is part of our studies.

currently doing an assessment about COPD and i stumbled upon this video, just wanna let you know you've cleared ALOT of my confusions with this video and would like to say that you're doing a great job :D!

1st year nursing student here... Your video help soooooooo much!! Thank you!

Thanks for this video, I am doing a presentation on COPD in relation to epigenetics in a couple of weeks. This has helped me a lot in my understanding of the disease.

This video is fantastic, thank you so much for this. you have made this very easy for me to understand and now i can get a good grasp on this disease and how it works. Keep the videos coming!!

This video is excellent!!! I actually got a better understanding of COPD. Andrew you are an excellent TEACHER. The demonstrations were made to be understandable. Thank you so much, i will be looking for other material that you teach !!!

can't believe this video received a thumbs down.... awesome informative and step by step explanation of the disease.. thanks!

Terrific video, very very informative while also not delving too deep into terminology so as the confuse. Currently doing a university assignment on the effectiveness of indacaterol on COPD and this has helped make sense of a lot

Having been a ore RU-vid Learner and of the You tube age, I really really REALLY appreciate this

great video. Thankyou so much for discussing it like that.. I would want to know a little more about the cells and mediators driving the inflammation and compare it with the cells and mediators in asthma

Thank you so much for this video! I'm a nursing student, and this video has really helped me understand COPD.

Thank you very much for the explanationof PFT and alveoli function and structure with surrounding environment.

Awesome - quick, complete, interesting (very calming voice), and I feel like a better prepared student! Thank you!

I have a nursing exam tomorrow on this. This is so great! helped me heaps. :)

I enjoy all of your videos. Thanks for your time and commitment.

Your videos are amazing and easy to follow. Very happy I stumbled upon this.

Thanks for this terrific explanation. Big help for my paramedic panel assessment coming up.

Hi i am from germany, and I appreciate all of your videos. In germany these instructional videos are not so perfect, so i prefer looking a video even in a foreign language - and by the way you teach me english. So if I want I could even go abroad an still work as a nurse! THX for all!

Thanks! Great explanation and so much easier to understand as I study and prepare for National Boards for advanced practice nursing and NP🙂 certification

Very nice, clear voice and the explanation is easy to understand. wish i had professors like you. nice drawings too. using a wacom tablet or something?

By the way. I love the way you present the concepts. Very easy to understand.

Good overview. I'm an old school resp therapist, and I was taught that asthma is also a part of the COPD disease group, albeit very different in origin from ch bronchitis and emphysema. That said, much of the treatment is the same.

Your videos are great!I I really appreciate all the effort you go to. Thank you, please keep up the good work.

Great video. You've basically covered everything that I was confused about.

very well explained, I understood what you were saying even when you were using clinical terms, thanks....

Thanks Andrew! It started a bit slow . . . I almost navigated away. I am soooooo glad that I didn't. My doctor just informed me that I "may" have either chronic bronchitis or emphysema. I had no concepts about either. It may have made more sense for him to note that I likely had COPD Thanks again for the very informative video.

one of the best videos for the laymen I have ever seen! great job !

Audio was perfect, and well worth the watch! Excellent, well explained lecture. Thank you

Great intro to the pathopyhs of COPD. Thank you, Andrew!

Excellent overview on COPD Dr Wolf. Will also be sure to complete the survey that you mentioned.

Great video, very informative, and you kept it basic enough without dumbing it down. Great job.

You explained it better than my professor. Thank you!!!

this really helped me a lot to understand COPD and your good at explaining. thank you

Absolutely fantastic video - extremely informative and well presented. Well done!

Hey man, awesome lecture! Your work is highly appreciated. What I like the most is your well-structured way of explaining the pathophysiology behind each symptom. I love you (no homo).

Really enjoyed your video. Was a great refresher of information that was easy to understand. Thank you!

this was awesome! great great video and i love the clinical add ins and details. Perfect for USMLE Step 1! you rock! In COPD what happens to the RV, TLC, ERC, IRC, VC and TV

this video was very helpful in clearing up the gaps my physio prof left in this subject- even though I am in vet school and animals dont smoke! but still can get COPD from chronic allergies!

great video! Very easy to understand, without dumbing it down too much. Thank you!

Thanks for the GREAT video It really helped me, I hope you've made one on pulmonary embolism.

This is amazing. Thank you so much!! Respiratory Therapy Student

thankyou, i found your explanation easy to understand for a nursing student.

Very informative and Great for a visual learner. Thank you

Fantastic video!!!! Im actually starting to understand some of these concepts! Cant thank you enough!!!

fantastic video- really explained things clearly and succinctly

Excellent video. Very explanatory!!! I have a better understanding of COPD and its pathophysiology now. Thanks for making this video

Very well explained, easy to understand. I liked it very much. please keep posting more. thanks you so much Andrews!

This was fantastic, thank you very much for this great explanation!

Great video. Will be checking out more during this semester in nursing school.

Such a good explanation, i have an exam on Tuesday, this has helped a lot! Thanks :)

awesome vid, as usual. However, what is the mechanism for destruction of elastin and collagen fibres with emphysema?

So would the use of a bipap machine be better for a patient with just emphysema when compared to the use of a cpap machine? and vice versa for a patient with just chronic bronchitis?

Andrew, I'm a COPD Patient of 3yrs now and I thought I was pretty well versed on my disease but I learned so much from your discussion, Thanks! My ? is the following: My blood count sometimes gets as high as 27. Is this due to the Hypoxemia? Is it trying to compensate for the Co2 poisoning, or just trying to get more oxygenated blood to circulate? I get it pulled once a month to keep it in ck. Trying to get a better understanding. Thanks!

Fantastic video Andrew!!! I appreciate your videos so much!!! Very well done.

Great vid. Now i'm going to studie the books. This is a great introduction and visual information.

Thanks for the video. Great addition for my studies. Greatful!

This is by far the best explanation of copd! Great great work Andrew. Any Plans of doing video of CPAP in Hypercapniac ARI ? Best Regards from a german Paramedic.

can you please make another lecture relating COPD to fluid, elctrolyte and acid base balance? thank you

Your videos have been very helpful to me! Thank you

Andrew, great video. Very informative and easy to understand. I have been recently diagnosed with COPD from a chest X-ray in which my diagram appeared flattened. I have not had follow up breathing capacity testing yet but will soon. I have never smoked or had exposure to chemical pollutants. You referred often to the explanation of causation due to smoking - what is your knowledge of those in my situation who were not smokers or had the pollutant exposure? I have no cough or breathlessness.

Thank you very much for the video. I found it very informative and appreciate it. This may be out of your area of expertise but just wondered if there is not a way to clear some of that mucus out of your lungs so it does not restrict air movement to the smaller airways? I remember quitting smoking years ago and recall coughing up a significant amount of mucus for quite some time after quitring and it seemed my breathing improved afterwards.

I am preparing my PPMM formative assessment, very helpful, well done

Can you explain co2 retention and why we don't want to bring O2 saturation to high in acute exacerbation
