Respiratory | Spirometry: Lung Volumes & Capacities 

Seriously, what do schools have against speaking like a normal person? Hearing these capacities and volumes in simple terms makes them so much easier to understand, especially when you have to explain the results back to the patient!

This video was very detailed. My professor took 4 hours to explain this in which I didn't understand, while this only took 20 minutes for you to explain and I fully comprehend. Thank you, you are most definitely a life saver.

This channel is a gift from God

7:45 The sound I made when I took my first quiz in med school 🤣

6 years later I find your videos so helpful. This is evergreen content right here ❤

I REALLY want to give you a big hug... possibly cry on your shoulder... you have been SO HELPFUL... I GET THIS!!! BECAUSE OF YOU!!! THANK YOU, you are wonderful.

16:25 when it's 12 am and u see how many slides you still have left

having sat through 3 hours of med school lectures on this concept, I can say that you not only crushed this topic in 22 minutes, but you have made this EASY. Thank you thank you.

thanks for explaining this. you may not be able to work math out in your head but you have the gift of teaching. very helpful, thank you. keep up the good work!

not all heroes wear capes! Thank you!!

This channel is fantastic. Myself and my three roomies are med students and use all your videos as great review tools in preparation for exams. Succinct and to the point! Why cant all professors teach like that? Keep us the awesome work

Excellent! It took me 12 years to finally understand this! Each time I would learn it, I forgot it, but it sticks now...Thank you! Thank you!

I love his teaching style! I wish I had him as a professor in person. Thank you for this video!

The definitions that my professor gave me were so complicated and they all sounded pretty much the same. Zach just came in and enlightened me like it was child's play. You're truly impressive, sir.

It's 2020 and I'm a first year medical student here in the Philippines. I just want to let you know you are literally saving my time from pointless reading that I couldn't comprehend easily. Thankyou!

Have a Respiratory physiology exam tomorrow. Watched your breathing mechanics videos, your compliance and elasticity videos, and finally this lung vol and capacity video and it helped SO MUCH. You truly are an amazing teacher. Thanks so much for taking the time to explain thing so well!

This is EXACTLY what I needed. You are a GEM! Thank you for putting it in terms anyone can understand.

Nicely done. I am a respiratory therapist and I have worked in the PFT function lab doing spirometery and pulmonary function tests for over 30 years. This is one of the most misunderstood and underrated diagnostic tests ever. 👌

I've finally understood this when my Physiology exam is just 12hours due...Thank you Ninja, I really appreciate!!!

This guy makes me understand anatomy on a different level!!! i just have to study now. I hope I get a good grade on my exam. This guy loves his job and it shows! thank you!!!

These videos are saving my life trying to do vet school in the reign of COVID online teaching. I appreciate you!

Wow!! You have simplified something so complex (or so I thought ) into an amazing 22- minute video. Thank you so much!! You are a Rockstar!!

I am a PTA student getting ready to take my boards, this has been one of the more challenging subjects for me. This video really broke it down and made it make sense! Thank you !!

Simply love this guy and the Ninja Nerds videos.You helped me understand this respiratory field that i am pursuing.Thank you for giving us your time and day. Your the best and im a addict for your teachings...

Thank you so much for making this video. You help me understand all of the concepts I need to master to do well in my nursing program! I can't thank you enough!!

Looking at a spirogram was initially quite daunting, but your explaination was clear and easy to understand. Thank you!!!

Thank you! There is no better feeling than understanding! I was really feeling discouraged. Now, to watch the next video.

Amazing, just amazing, no such words can describe my admiration and appreciation towards this channel ninja nerd and this outstanding teacher.

Thank you so much for such a wonderful, easy to understand explanation. I've covered this topic numerous times throughout my education but could never grasp it - finally, thanks to your efforts in breaking it down and REALLY explaining it, I feel like the light bulb went off in my head. I appreciate you and your team so, so much. Much love!

i got lightheaded watching this cause i started breathing all sorts of whack. but great video!

My girlfriend is battling through PA School virtually (primarily) right now, and these video lectures have been a lifesaver. Thank you for breaking these concepts down into terms that are easier to understand!!

I know I'm a little behind on watching your videos, since it's 2020, but I am doing remote learning due to the COVID-19. I really appreciate you taking the time to explain EVERYTHING!!! You have made this concept so much easier for me to understand!!!

I wandered so much for this particular topic but I was back to you Ninja Nerds as always. 😊

Thank you!!!! for all your videos and for going in depth in different subjects, and making them easier to understand in order to memorize.

you hold a special spot in my heart

U r an inspiration, i am a Clinical Instructor working in India, and all my students are very satisfied with the classes i take, all thanks to u Sir, keep going much much love from India

I love you sooooo much Team Ninja herd. Med school is easy just because of you. You're helping us become great doctors with better understanding of the concept in simple language.

As always, you saved the day. Thanks for sharing your gift of teaching!

literally the best video so far! you are excellent at pedagogy too!

Simplicity is just the way to go sometimes, ya know? This was a really great video. Really helping me with my studied in med school

I am glad that I found you. You made everything so easy.

Because of your videos i started loving physiology.. thank you..well explained ..

Thank you so much Zachary! I just couldn’t get this concept before. You make it make sense!

You are amazing 😍 Now my concepts are crystal clear. Thanks a lot for making such an amazing content❤️

Thank you so much! I'm taking physiology now & even though my professor explained it pretty well, your video really helped to put it all together for me.

This was great! We are six lectures behind in A&P2 and have only three lecture classes left till finals. Our lesson was basically, "here, learn this". Thank you!

very efficiently explained. I never had a chance where I need to rewind the video to understand again, it was going so smooth and simple.

It would be an understatement to say I love this channel!

amazingly thorough, perfect explanation. using this to study for my NPTE. thank you!

I have physiology exam in 2 days and you saved me a lot time my dude! Thank you and keep up the good work!

My physiology exam is tomorrow and i was confused how to do this respiratory hell of lectures but here i am getting everything inside my brain easily through your videos , We are all lucky to have you thank u so much :)))) >3

Simple, clear and passionately taught. Thanks so ;much for sharing your expertise with us.

Have gone through this topic so many times but only got it after watching your video! Very grateful for your talent in teaching :)

Watched three videos on this topic, all were helful but yours was the most clear and helped the most! Much appreciated.

Ur classes are amazing!!! On everytime while I read this lung volume concept I am very confused . But this time it is easy for me .Thank you very much for ur wonderful class

Thank you so much for explaining this in so much detail. I couldn't understand the lecture during my lab at school and you are making it so easy and simple.

Thank you again my lifesaver, seriously! Not only did I understand, but I enjoyed the whole 22 minutes too and didn't feel the time! Much respect to you! p.s. This time I didn't slow down the video! I was able to catch 90% of what you said with ease! Big progress!

Helpfull and interesting as always. The perfect exam prep!

Thank you so much sir for making Respiratory physiology easy. Be blessed

Yes! So helpful! My textbook had me completely confused, but thanks to this video I think I will be able to pass my exam tomorrow:)

I loved this video . Easy for me understand a difficult content!! The graphic help me a lot !!

You're so perfect teacher. Blessed to have you.Loads of Love from India 🇮🇳

one of the best explanation i have ever seen. thankyou , add more knowledge by giving more lectures .

Lung disease patient very grateful to be able to understand all this, thank you xx

In my favorites now. Great explanation. Thx!

This video explains it perfectly! Very helpful getting ready for NPTE, thanks!

A real ninja teaching the lesson, what a master!!

Thank you Zach for this. I had to skip the pulmonary function test chapter while studying because of all the maths. I'm so happy I opted to use a video now, I can study it with so much ease now🌹

Loved it.Really I can’t explain how much I have struggled earlier to mug up these definitions but thanks to u dude🤗

best lecture of lung volumes and capacities so far... lecture delivery is done very well.Finally i got that 🌼

As a med student I find I have every resource available to me, except TIME! You make difficult concepts feel very doable in a reasonable amount of time and so this hopeful future doc THANKS YOU for all of your hard work! Keep em coming!

I wish I could give this video a 100 likes. Bless you man for being so awesome. I also need to thank my colleague that got me watching your videos. So informative and super useful!!!

Great video! This was one topic I always struggled to comprehend. But, the video made it easier; explanatory and simple to understand.

Video keypoints: -peak- Tvi (inspiration) / Tve (expiration). -normal 500 ml + forceful inspiration -> inspiratory reserve volume (IRV) (2800-3100 ml) (5800-3000) -forcefully exhale -> expiratory reserve volume (ERV) (1200 ml) -tidal volume - ~500 ml (in and out) -Air remains in lungs, so they don't colapse (alveoli remain open). -> Residual volume (RV) (1200 ml) -Inspiratory capacity- IC- total volume you can bring in. Tidal volume(i) + IRV = 500 ml + 2800 ml = 3300 ml -Expiratory capacity- EC- amount of air you can breathe out. Tidal volume (e) + ERV = 500 ml + 1300 ml = 1800 ml -Functional residual capacity- FRC-- in normal breathing the air in the lungs is ERV + RV = 1300 ml + 1200 ml = 2500 ml -Vital capacity- VC- Tidal volume + IRV + ERV = 500 ml + 2800 ml + 1300 ml = 4600 ml -Total lung capacity- TLC- Tidal volume + IRV + ERV + RV- total volume lungs occupy. = 5800 ml Test- forced spirometry - next video in detail. Determine pulmonary function- restriction/obstruction. -> If you found this resume useful, subscribe to my channel :)

sending virtual hug! thank you for simplifying this concept.

Thank you so very much this absolutely informative and nicely illustrated and even the math. had been used meaningfully and thoughtfully ... I'll keep following your great presentations in the other videos ....

Excellent presentation. Ist time in my life that I have an absolutely clear understanding of lung volumes and capacities.

You are just the best of the best, you made my work easier Ninja👏🏽👏🏽👏🏽

you are a very good teacher. Thank you for your time

Very easy to understand, thank you! I have a practical on this in the morning and feel ready already!

I love your videos they help so much as I'm in medical school and one of my teachers are the worst at explaining everything so this is very helpful !

My new favorite channel for stuff like this! Definitely subscribing!

I wish i get you in my first years of medical school .you are my inspiration . Thankyou

Really great video. broken down so well. Thanks for helping me pass my exams!

Speechless....simply amazing how you explain. Thank you

What an explanation. Absolutely loved it.

Thanks man, I appreciate your lectures. Its very helpful.

Thank you so much for your excellent clarification about lung functions and capacities !

Super great video; smooth and lovely explanation that just goes straight away to your mind.

I just keep coming back to Ninja Nerd Science when I go on a course for something new to get me a refresher. Great stuff!

Excellent description; thank you 🙏

This was the best video ever! THANK YOU!

Best video! very well explained. Thank you!

Awesome sir ,I never heard such a beautiful explanation of graph....thank you for clearing this vital concept such a easy manner...

Thank you so much for this video! I was so stressed about understanding this, but your video made it all clear!

I love you will you. I never thought I would be able to understand this.

Im Currently in nursing School And im taking anatomy and physiology right now and Ninja Nerd been a Huge help for me my score average is about 90% per test and quizzes all because of your videos. I really appreciate your content and how you dedicate yourself to teach the YT Community . Thank you👌🏽💯

God bless you. I have read this for almost 2 hours without understanding. You used just 20 minutes. I understand now. Thank you

What I don't understand about our education system from preschool to PhD, why are educators required to have so many degrees and still cannot teach effectively. I had someone tell me you needed a degree because otherwise are not a good educator. NOT TRUE! I had an English teacher in high school say you don't truly understand something unless can explain in simple terms. This is it here! I have had professors with doctorates and no one by the end of class understood a word. I just don't understand. This is what a teacher exemplifies. Fantastic class.

Thanks for the lecture. I was just confused about this topic since my school. You explained it well. Thank you...
