Drbeen this is by far the most amazing lecture for me on this Topic as it has been very difficult to comprehend. Your style is gold. I watch from Nigeria in Africa. Thank you for the impact on the medical students and doctors here in Africa

As a Physiologist I appreciate your great service to medical professional throuhout the world. I am in India. I was able to finish MD physiology through your and Dr Najeeb's concept oriented lectures. I request you to post a lecture in compliance and elastance of lungs.

@DrBeenMedicalLectures 7 лет назад

Great to hear. Happy to help. Dr. Najeeb is my big brother. Definitely a great instructor, world's best if I may. Lung compliance and elastane lecture will be uploaded soon. It is already on drbeen.com site though.

@shilparsoni427 6 лет назад

It was here you on dead space and ventilatory rates topic, but at 33:07 minutes you have done the calculation which shows 500*4/40= 50 butit would have been 500*1/10=50. thank you

@drYK786 6 лет назад

Sir, watched your video..it's really awesome.. Question: what happens to air which goes to defected alveolus or alvelolus which doesn't function for exchange,is total volume of air exhaled or is there a same condition as in functional alveoli????

@inam9661 6 лет назад

Ayush bang disease copd ,pulmonary fibrosis,pneumonytis ,physio logical dead space can increase because distarvation in either ventilation or perfusion....

@ihsanullahstanikzai8905 5 лет назад

dear sir, Why a normal AV is less than effected alveoli volume. Effected AV +anatomic dead space become 200ml . If Effected AV not avilibale the anatomic dead space alwaye avilable that equal to 150ml. So ot can 50 ml ???

@mjgalatas 4 года назад

Help me understand why at 27:00 you define Alveolar ventilation as (Vt - Da)*10, where Da is anatomical dead space resulting with a value of 3500ml, and then at 32:00 you define it where Da is alveolar dead space with a resulting value of 4500ml. I don't understand how there are two different definitions of the same term with two different results. How are the two values used clinically if they are different?

@humblehumanbeing3956 4 года назад

Hi sir; Please answer... 35:00 How can be alveolar ventilation 450 Anatomical Deadspace was 150 ml Also if physiological Deadspace includes the anatomical one; it should have been highter than 150 ml How can it be 50 ml as according to our calculation

@wakylaugh 4 года назад

Physiological dead space is the total dead space in the lungs

"Terminal bronchiole "is not a part of respiratory zone it's a part of conducting zone

@zakariaalkishik 5 лет назад

there is respiratory bronchioles that have some alveoli

@beautyofnandl3149 5 лет назад

Zaharia is right bro

@stargirl7963 4 года назад

Yeah it's respiratory bronchiole.

@vimikoolwant8499 6 лет назад

Hello sir It's a great lecture but I didn't get one thing How can the alveolar ventilation be 4500ml/min if one segment is providing dead space Should it not be 200ml dead space? Because 50ml added up with the anatomical dead space of 150ml Would be great if you could clear it out

@ada5435 6 лет назад

i thought the same ....there is something wrong in his calculations....AV in normal is less than in affected alveolis

@FaizanKhan-nw8ku 6 лет назад

I'm writing this to ask for a clarification... at approximately 22:50, when the alveolar contents were being drawn, Dr. Syed mentions that the content of 150mL that comes back in from the deadspace has the same composition (and then he points to the 1st alveoli drawn) and says CO2 = 40mmHg, and O2 = 100mmHg. Then he proceeds to mention that the 150mL that came in will NOT participate in gas exchange because it has the same contents as VENOUS blood. But the CO2=40mmHg and O2=100mmHg is ARTERIAL blood composition... so which is it...?? Will it not participate in gas exchange, upon entering the alveoli, because it has venous composition or arterial? Because if it had arterial, as was stated in the video, then the air is O2 rich and should want to participate in gas exchange... but if it is venous then it's O2 content will be low and CO2 content high, preventing it from participating in gas exchange. Your help and knowledge is greatly appreciated. -Faiz

Apologies, it's at about 22:00 onwards... somewhere within that area.
