Best video regarding this topic sir,thank you soo much🙏
these videos are like watching episodes of netflix , one gets hooked on it when he starts watching until video ends
Exuberant titan Thanks for finding the videos to be so engaging. Yes, I shall try my level best, and upload more and more videos (GI reflexes and others) as and when the students demand those topics. And , with greater frequency too.
Thanks again,
Regards,
Thank u sir for simple explanation 🙏🙏
Thank you sir
Sir please make one video on decorticate rigidity ,decerebrate rigidity 🙏
thank u for ur effort , these vidoes more help full for me sir
Thanks!
I am like addicted to your lectures please guide me how can I get your lecture's thank you sir
Zaheer Ahmad I think didn’t see the comment earlier. So , pardon me for the delayed response. Soon, i’ll make a plan for how to watch these videos topic by topic, and shall organize in a better way. Thanks,
Regards,
In copd high o2 not given can you explain
You are best sir!!!!!
Thanks! Teachers derive motivation to do better and better, from the students and great reviews....!
Regards.
Love from Nepal❤️❤️❤️❤️
Thanks!
Sir kindly upload deep sea physiology ..will be grateful😊
Yes. It's coming up next.
Thanks.
sir, please make a detailed video on cyanosis
Exuberant titan point taken. Shall upload cyanosis (and indeed more of clinical physiology topics). However, i’ll finish the pending topics first.
Thanks...!
Sir why breathing in pure O2 does not give 100% haemoglobin saturation at all altitudes?
Consider oxygen to be a continuuum - from air, to respiratory passage, to lungs, and finally blood, where it first dissolves in plasma and the enters the RBC to saturate the Hb. In hypoxic conditions, such as at high altitudes, the low PO2 of atmospheric air would cause a lower amount of O2 (and hence lower PO2) in plasma. So, when 100% O2 is inhaled and it goes to alveoli, there will be a large PO2 gradient from alveolus to plasma. Hence, it will diffuse rapidly and reach equilibrium from alveoli to plasma (dissolved O2). This will provide O2 with lesser time to enter red cells and saturate Hb. So, Hb saturation may not be complete. [Anyway, maximum saturation of Hb can be up to 97%, as some forms of Hb do not take up O2.]
Sir , Your video helped me a lot to understand the mountain physiology.
Thank You.

Hi. I am glad the videos are helpful. Please let me know if any other topic is needed.
Regards,
sir how can I access to you lectures.
There is a prepladder app - “physiology by dr Vivek Nalgirkar”. You may subscribe to it. Another app is “physiology guru”. It has my lectures. Plus, this channel will continue to have regular uploads of my lectures. Regards,
There is no audio sir
I checked on 3-4 different devices. Audio is there.
Could you please check again?
Thanks.
Now it's working sir
Thank you 🙏
