Acid base disorders with case discussion

Metabolic acidosis
Metabolic alkalosis
Respiratory acidosis
Respiratory alkalosis

Acidosis
decreased pH

Alkalosis
increased pH

Metabolic acidosis
primary defect- decreased bicarbonate

Compensation - hyperventilation by lungs

Causes

High anion gap metabolic acidosis
DKA
lactic acidosis
renal failure
organic aciduria
aminoacidurias

Normal anion gap metabolic acidosis
Diarrhea
RTA
intestinal fistula

Metabolic alkalosis
primary defect- increased bicarbonate

Compensated by Respiratory mechanism- hypoventilation

causes

vomiting
upper git obstruction
adrenal tumor
Cushing syndrome
glucocorticoid excess
mineralocorticoid excess

Respiratory acidosis
primary defect- increased pCO2

Compensated by renal conservation of bicarbonate

Causes
pneumonia
COPD
asthma
Narcotics and sedatives
paralysis of respiratory muscles

Respiratory alkalosis
primary defect- decreased pCO2

Compensated by - renal excretion of bicarbonate

Causes
Hypoxia
High altitude
Hysteria
hyperventilation

This is the best youtube channel for biochemistry lectures, myself got so much educated by your lectures sir, HEARTY THANKS TO U SIR 👍👍

[pritam_medico]

Thank you sir... In my medical college they only use PPTs... And most of their lectures are boring.... Thank you for chalk and talk method... Much needed... We need more videos thank you again sir😌

Sir, you’ve been a life saver for me. Studying one night before the exam with the textbook opened in front of me, and listening to your videos. Correct correlation 👍🏻. Thanks a lot !

[secrettripuri]

I am mbbs student sir, I very appreciate on your lecture, keep on, because In our college teachers not teaching like writing on the board, the teacher only giving lecture by the computer.IT IS VERY VERY HELPFUL TO US, THANKS SIR

Meta. Acidosis(hyperkalamia) - respiratory alklosis
Meta. Alklosis- respiratory acidosis
If h+ increase, ph decrease(meta. Acidosis) so lung do blow out pco2 so Decrease pco2 ( respiratory Thank you sir
-In Diarrhea basic substance come out from body, git become acidic
-In vomiting acidic substance come out from body, git become basic

Hello Sir
I watched this video during my first year University examination and today watching to study in my finalyear medicine posting
Your work is wonderful Sir
Thanks a lot❤

[Gundleefamily]

acid base was so difficult earlier but with your lecture, now I understand the concept. thank you again and again

[prateekkumar]

Finally ..! my concept of acid base imbalance disorders is cleared
Thanks a lot sir

[SameerShaikh-wjui]

The lecture was in simplified form and i understood it properly my concept are crystal clear. Thank u sir.

[arpasr.]

Amazing lectures! Why didn't i find them earlier!! 😊

[raksha]

watching this before my biochemistry quiz, I don't why I wasted my time attending lectures when I can just watch your amazing videos THANK YOU

[ghostify]

Sir you are just saviour💪 for us ty for teaching us biochemistry the subject which i had never touched and finally i ahve completed it in a month unknowingly by just listening to ur vds and making handwritten notes ty sir 🙏 🙏🙏🙏

[koduripravallika]

Really u r videos made more interest in biochemistry sir 😌 lots of respect 😇 thank u sir

[ayushi_]

Thank you sir. You made this concept a piece of cake to learn. I spent days understanding this but always ended up confusing and mixing everything. Finally happy 🤩 yayy!

[hariharasudhang]

I am continuously following your lectures after my college lectures

[ananyashukla]

Case study- metabolic acidosis and respiratory alkalosis ( compensatory)

[ritikaprasad]

I can't thank you enough to make this topic so clear to us

[stringomyelin]

Thank You sir! You're the BESTEST BIOCHEMISTRY TEACHER

[umerrajpoot]

Literally mn sakht depression mn tha is video se phle phir mn ne ap ka chemistry of protiens suna aur phir ye yaqeen manain muj jaise naiq ko b samaj aa gai Sir Thankyou very much Allah ap ko duniya aur akhirat mn kamiyab karain ameen.🤲🤲

[mohsinfayaz]

The only reason for studying and understanding biochemistry!
