Flow Volume Loops - Respiratory Physiology - Pulmonary Medicine - Pulmonology Playlist

Flow-Volume Loops of the lungs…Respiratory Physiology…Pulmonology. The flow-volume loops can help us distinguish among obstructive lung diseases (e.g. asthma, emphysema, chronic bronchitis “COPD”, bronchiectasis) and restrictive lung disease (e.g. interstitial lung fibrosis, sarcoidosis, asbestosis, coal worker pneumoconiosis,…etc.)

I was crying studying this by my own, but when I opened your video not only I fully understood the concept but also burst out laughing. Thank you so much

[@MedicosisPerfectionalis]

My pleasure 😇 Thank you so much for watching! Good luck 🍀, Dana :)

[@carolinefallon1625]

Great lecture. The case answer is "A". Phrenic nerve injury acts as a restrictive flow pattern. Trouble with inspiration, can't get as much air in, decreased TLC. No scalloping in exp phase.

[@fredoneazx3106]

Man I really wanna thank you so much. I HAD MY EXAM today and got a massive A thanks to you. Your work is amazing

[@MedicosisPerfectionalis]

Thank you so much!

[@elijahappau1936]

Thanks a lot. I will go .for 'A' for Case 15.. Diaphragm is a powerful muscle for inspiration..hence inspiration is affected (Restrictive) ... shifts its shape to the right of the normal.

[@samfru22]

The coving in obstruction loop is due to the first part being effort dependent which is normal so straight line while the second part is effort independent expiration which is affected in obst lung disease also called "dog leg/scooped out pattern"

[@tripunk]

Thank you for explaining this!!

[@nuttamonthongyot195]

at 12:05 i think the blue TLC line should reach from volume zero to volume 6 not from volume 1L to volume 6. otherwise youre showing fvc not tlc. otherwise great video!

[@jkadbhjadhboa]

Great lecture! I just wanted to point out that the back extrapolation volumes on those flow-volume loops are unacceptable and would be considered unusable per technical standards. I don’t mean to split hairs but I think it’s important that any viewers who may be involved in interpreting PFTs be able to recognize acceptable testing maneuvers. I look forward to watching more of your content.

[@42-sandeepmalthumkar72]

The answer is “A” and u r a life saver🙏🏻

Thank you for the video! I am a bit confused about maximal flow rate... our prof told us that the max flow rate happens at the equal pressure point which is a bit after that peak. But it's not the highest flow... how does that make sense? Thank you so much in advance.

[@SarkisKlinik]

i see in your flow-Volume graph that volume values in the horizontal axis goes from higher to lower numbers like 5 , 4 ,3 , 2, 1 ... But in my machine it is the opposite , it starts from zero and goes higher. is this problem ?how to interpret when i focus on this area or how to know if RV or TLC is increased according to my graph curve ?

[@miriami7]

SHUKRAN , you are the BEST!

[@MedicosisPerfectionalis]

You’re very welcome 😊

[@bagadimusic2086]

Can anyone tell me where idls fvc in graph. Is it the area under the loop of expiration or just number on x-axis

[@SarkisKlinik]

in flow-Volume graph , what is the reference values of RV and TLD by liter?I see in your graph curve RV is 1,2 and TLC is 6 L . is this value applicable to everybody ?

[@horschiday9449]

[@MedicosisPerfectionalis]

Thank you 🙏

[@cherrrriii]

thanks alot for this! i have a question though, why does the TLC increase during obstructive lung disease, i though if RV will increase and FVC will decrese wont that keep TLC normal?

[@arwinraj861]

My guess would be C sir , cuz the diaphragm contributes to respiratory but there are other inspiratory muscles that can compensate, so the graph will be similar to a normal graph in shape but reduced in all other aspects in term of amplitude. Am I right?

i have tried FVC test on myself, The inspiratory loop on flow volume loop did not arrived to starting zero point , it ended shorter on curve , is this problem ?while doing the FVC test , should we always close the curve of inspiratory loop completely bring to zero point by inhaling with stronger effort?

[@tulipflower37]

what isthe answer of the last question? could it be a restricitve pattern as air cant get in due to diaphragm dysfunction?

You are always saving my graphs doc thanks for real

[@MedicosisPerfectionalis]

You’re always welcome, Menna!

[@kavi7845]

You explained it really well. Thanks a lot sir.. I think the answer is 'a' for the case15.

[@gilaurusalcoran]

Amazing lecture. Thank you

[@SarkisKlinik]

in flow volume loop , is the end point of expiratory loop is considered RV ?my machine does not calculate RV parameter, but my machine has flow volume loop graph. So from graph, i can myself know the real value by liter of RV , right?

[@tashprincess11]

How do we differentiate intrinsic vs extrinsic restrictive lung disease using flow-volume loop?

Is answer of q 15 option C as diaphragm is failing to contract and so it's extrinsic restrictive lung disease ?
