Pulmonary Volumes & Capacities

A brief introduction to pulmonary volumes & capacities including tidal volume, inspiratory reserve volume, vital capacity, and total lung capacity.

[@ishagupta6514]

awesome! reading from text book was tough..u made it easy thankyou!

[@clairemckenna9358]

You just somehow made this all make sense, I was so confused before!

[@bwm258]

Studying for the NPTAE and I think I FINALLY got the formulas for breathing! Thanks!

[@sherylrox4867]

I couldn't understand anything in my textbook but when I watched your video and then read it again , I was able to understand all the volumes and capacities except functional residual capacity..... well , thankyou for recording the video...!!!

[@LWard-vo5wh]

Thank you--studying the physiology for anesthesia school--most helpful!

[@LWard-vo5wh]

***** done!

[@mennaghareeb159]

Hi thanks for the great video but isnt the total lung capacity = vital capacity+ residual volume ??? Cos in the video its a minus

[@edgarlozano6534]

Thanks for the explanation! I understand it way better now!!

[@HealthEdSolutions]

Glad it helped Edgar!

[@christianswanson3515]

Very helpful. Thank you, Andrew.

[@HealthEdSolutions]

Thanks Christian!

[@kpash22]

The residual volume is actually included in the total lung capacity. Great video! It was helpful seeing all of this in 1 place!!!

[@bearmimi99]

I was struggling with these lung volume terms. Glad I found your video. Explained the basic concepts clearly! Thank you!

[@HealthEdSolutions]

Glad it helped!

[@TruthReviews]

Wow, you are soooo much better than my lecturers at explaining things. Love your videos. THANK YOU!

[@TikiJeepSam]

Well thank you for this! It cleared up reading and rereading this section in my A&P book for the millionth time and not quite decoding the words! :) And Your drawing matches the graph in my book exactly so It was really easy to follow and learn.

[@HealthEdSolutions]

Thank you Samantha! Glad it helped!

[@benjojola8424]

Gina that is great to hear!

[@mcods2001]

I liked the simple explanation along with the color coding.. better than my under grad schooling.. keep it up. cheers.

[@tombarciaptdptatc6795]

Great introductory video. Very clear instruction and encompassing.

[@HealthEdSolutions]

Thank you Dr. Thomas for your kind words!

[@skipTogether]

I was having a hard time visualizing the volumes and sums. This video helped me finally understand -- Thank you!

[@HealthEdSolutions]

Really glad it was helpful!

[@anikixvi]

Thank you so much!! You make it sound so easy and logic thinking, i dunno why the docs at college love to use Big Words. I know that's more scientific and all but...that only confuses me....
So Thank you!

[@TammyOluyole]

Excellent video!

[@RawadNasr]

Thank you for the video, very clear and concise.

[@AliJ23]

Lol I when you said minus in the end I was like huh then the annotation popped. XD

VEry helpful thank you!!

[@juwelen6168]

wow!!... nice working I like it

[@HealthEdSolutions]

Thank you!

[@asenatful]

Still there is (Functional residual capacity) it's RV + ERV , you forgot to mention

[@HealthEdSolutions]

Good feedback. Thank you!

[@MoveInSilence2444]

Thank you so much sir, your explanations are so easy to understand!

[@armanmoradi5096]

Great video 👍

[@HealthEdSolutions]

Thank you!

[@charlenekinsella5065]

Fantastic video, thank you! :)
Quick question, when a person inhales to their maximum capacity, the extra volume of air is known as the _______ volume? I'm stuck on this question. Thanks a lot!

[@mjmjcp83]

THANX!!!!!!!!!!!!!!!!!
helped a lot.

[@adityabansal619]

very very good explanation
thanks

[@HealthEdSolutions]

Glad it was helpful!

[@MrBesart5]

@Charlene Kinsella-The answer to your question (I believe) is the inspiratiry vital capacity(IVC).

[@queendiamond1969]

This was a good simple explanation for the points mentioned but I noticed that functional residual capacity wasn't included. Any reason in particular???

[@eugeneciccone9783]

Is not the total lung capacity the Vital Capacity "+" the residual volume?

[@haydengolay4647]

Yeah, he messed up

[@johnnyappleseed5476]

WOOOO GONNA ACE THIS PHYSIO EXAM NOW THANKS

[@HealthEdSolutions]

You're welcome!

[@NurseNeoHealth]

thanks mr wolf

[@srishankarbharati]

this topic is otherwise easy to understand but difficult to remember ....this video helps us clear our concept and help us memorize very easily.

[@HealthEdSolutions]

Thanks so much for the feedback. Glad it helped.

[@anjali1826]

what is functional residual capacity

[@cinusmitha]

Well said...

[@megatfitriaziz]

Hi you mentioned that TLC = VC- RV , isn't it supposed to be TLC= VC+RV or VC= TLC- RV? But however, you can't really measure the RV unless assumed, 1200ml in a normal healthy person, right?

[@Theodinsson]

we did this in physiology and the instructions were : use the spirometer while sitting.
Isn't this totallay wrong ? Limiting the mesures ?

[@anasissa8555]

Nice explain

[@dionnawalton6069]

thank you!

[@HealthEdSolutions]

Thank you for watching Dionna!

[@emilydecicco9347]

excellent.

[@HealthEdSolutions]

Thank you Emily!

[@chharia1]

great thanx

[@salimalalani2000]

This should become part of the khan academy videos for the mcat

[@HealthEdSolutions]

Thanks so much!

[@inurihettiarachchi9780]

OK so vital capacity is the max possible volume available in lungs for both inspiration and expiration. Am I right?

[@HealthEdSolutions]

Thank you for the question. We have passed this along to the medical review board at Health Ed Solutions.

[@neveradullmoment6]

What if your tidal volume is less than the anatomical dead space? This would technically mean the alveolar ventilation is negative given the equation. (tidal volume-dead space) x respiratory rate. But I don't believe the ventilation can be negative. lets say tidal volume is 100 ml/breath and dead space is 120 ml.... shouldn't each inhale direct 100 ml of air into the lungs?

[@HealthEdSolutions]

Thanks for your input. We've passed this along to our medical review board. Sorry for any delay as this comment went to the spam folder.

[@chelsiecasey4872]

Is the total lung capacity vital minus residual or vital plus residual?

[@HealthEdSolutions]

Thanks for your question Chelsie. We have passed it along to the Health Ed Solutions medical review board. Thanks for watching!

[@animhaom]

great! thanks!

[@HealthEdSolutions]

Thanks for watching!

[@kaylathompson8539]

thanks

[@HealthEdSolutions]

Thank you Kayla!

[@spongebobooo1]

Thank You so much, i cant find this topic in my syllabus book xP

[@HealthEdSolutions]

You're most welcome!

[@danielg6542]

sharingggggg

[@kavitasudhakaran3306]

total lung capacity is vital capacity +residual reserve volume not minus reserve volume

[@wajeehakhan7436]

im confused about total lung capacity

[@HealthEdSolutions]

We will be rolling out new lessons soon. Keep watching, we appreciate the support!

[@Naamtey94]

thank you~ >/\<

[@psychosadat]

Awesome video but I think TLC=VC+RV

[@sharry2327]

TLC= vc+rv. Very good video though.

[@nedywbuny4614]

TLC=VC+RV.. Not minus. But cool vid. :)

[@seanhe6948]

so good.

[@HealthEdSolutions]

Thanks Sean!
