Dear you are the common sense doctor I like and I wish I would know you more and share a lot.You said." medicine makes sense when you explain ." I liked you so much I like reading Guyton,medical physiology text book for it really make you sensible doctor.I call a bit out of fashion for I despise these question and answer type of study purly directed at passing an exam,I know some times it hurts but honestly medicine is so great that way.Thank you for your superflowing explanation with ease.

@hussam7033 4 года назад

hello dr. I hope you do answer questions here. I am having a bit of a problem in understanding why in obstructive lung diseases there is decreased ventilation. I know that it is very intuitive to understand why but I clearly recall that the problem in obstructive lung diseases was in expiration not in inspiration. Perhaps it is wrong to associate inspiration and ventilation together but for some reason I am associating them.

Thank you from the bottom of my heart! You are a savior!!! I have a question in 19:14 isn't that supposed to be BRONCOconstriction instead of VASOconstriction??? As you explain in the next sentence, the purpose is to narrow the BRONCHUS (not the VESSEL), when hypoperfussion takes place... Or am I wrong??? I dont know, thats why I ask my savior! Thaaaaaaanks again!

Hi medicosis! i had a question about 10:48 when you mentioned emphysema leads to decreased V/Q ratio. What you say makes sense; however, everywhere online Ive seen that emphysema is an example of increased V/Q mismatch. Currently watching Dr. John B. West's resp phys lectures and he states that emphysema leads to higher V/Q inequality due to some ventilation but little perfusion in the destroyed lung tissue. Again, id like to say that both your reasoning and his makes sense to me, so its a bit difficult to piece things together lmao. Love your videos man, hope you can help! -a young M1

@svetlanakhaimchayev7894 3 года назад

The V/Q mismatch will always be mismatched, the closest that we will be to attaining 100% is in the middle of the lung? @ the apex we will have a higher ratio, and @ the base a lower, ratio? So when does this become a problem if it is always mismatched?

@zishanahmad7089 11 месяцев назад

Hi thankyou❤ Lower lobe infarction common due to more diffusion or more purfusion In your notes written diffusion while in your video speaking perfusion? Please explain

@manarabdelaziz6302 4 года назад

What happens to alveolar ventillation in theses cases 1- testrictive lung disease 2 -obstructive lung disease 3- airway collapse 4 increasing compliance ?!! Can you give me the answer as Unfortunately I cannot answer that

@Mikesco10 3 года назад

i have a question; i always see the equation written like this: Co2 + H2O H2co3 Hco3 + H ... y does it say co2 + water if CA is removing the water to form carbonic acid? another question; in decreased ventilation shouldn't the PaCO2 go up? or is normal because its corrected by increased respiratory rate?

can ventilation defect cause hypercapnia? less o2 is in the alveoli so i thought Paco2 would be higher

@MedicosisPerfectionalis 4 года назад

Hypoventilation can cause hypercapnia. Also, hyperoxia can cause hypercapnia.

@adityapaudel6016 4 года назад

Emphysema has low V/Q right? Damaged Alveoli causes loss in ventilation with same perfusion which will result in low V/Q.

@MedicosisPerfectionalis 4 года назад

Excellent

@abulmuslimchartaev8017 4 года назад

5:34 there is maybe a mistake. Part where “normal apex”. If I’m not right, explain pls

@MohammadYounos 4 года назад

Yes, you are right. At the apex of the lung both perfusion (Q) and ventilation (V) are decreased, but the decrease in Q exceeds the decrease in V, making the V/Q ratio relatively high. Otherwise, it is really a perfect video.
