Case scenarios: When you don't give patients 100% O2 and why

Clinical scenario #1: Chronic lung disease patient.

The ventilatory drive of patients with chronic lung disease is primary due to their hypoxemia, rather than CO2 levels. This is because pCO2 receptors are adaptive. Chronically elevated pCO2 makes central receptors unresponsive in COPD patients. Administration of a high O2 mixture to relieve the hypoxemia is contraindicated because this removes the hypoxic drive, leading to severe hypoventilation.

Clinical scenario #2: Drug overdose where central receptors are blocked.

Healthy food: Salads

Hey everyone!

I thought of sharing something that inspired me.. It's about nutrition (Not my regular study post!)

In this age where cardiovascular problems and cancer have been on the rise like never before, it has become essential for us to eat healthy. We need to cut down on bad cholesterol and encourage fiber, nutrient rich, natural, unprocessed food.

Recently, there was a salad making competition held in my mom's school. Children of the second grade helped their mummy's make salads in the school.

Iris repositor has a straight or bent "blade" with blunt edges.

IOL dialer has a bent "tip".

Human developmental index and physical quality of life index mnemonic

For Human Developmental Index remember, "Humans LIKe development"
So it takes into consideration: Life expectancy, Income & Knowledge.

Physical Quality of Life Index, "LIL physical quality"
It takes into consideration: Life expectancy, Infant mortality, Literacy.

For remembering the I in both mnemonics, I think that development is linked to money (income).
LIL should remind you of the little one, that is, the kid & hence infant mortality!

Mnemonics on nutrition

Hey guys!
These are some mnemonics I made on nutrition which is a part of my Preventive & Social Medicine (also known as Community Medicine).
We'll keep updating this section.
Please, please, please feel free to add your mnemonics as well ^__^

Deficiency of vitamin B1:
Thiamine deficiency causes Ber1 Ber1 (B1).

Deficiency of vitamin B2:
"A2 B2 C2"
A2 - 2 ATPs (FAD and FMN are derived from riboFlavin)
B2 - Vitamin B2
C2 - Cheilosis, Corneal vascularization
Let’s call it ri-two-bo-flavin!

Innervation of the tongue, palate, pharynx & larynx with mnemonic

Hey everyone!
We are learning innervation of some muscles today! Yaay!

Glossal means pertaining to or near the tongue.. That's your starting point.

All muscles ending in "glossus" are supplied by hypoglossus
..Except palatoglossus.

Why? Because palate!

All musles of the palate are supplied by the vagus
..Except tensor veli palatani.

Why? Because it's a tensor!
All muscles in the head beginning with "tensor" are supplied by V3.

Pharynx and larynx is easy too.. All you need is a mnemonic!

Anti-platelet drugs, receptor and their deficiencies mnemonic

Aortic arch derivatives mnemonic images

I made these diagrams guessing they'll be helpful ^__^

Aortic arch derivatives

The greater part of the first and second artery disappear. In adult life first arch artery is represented by the maxillary artery and the second arch persists for some part of fetal life as the stapedial artery.
The mnemonic people use for that is, "First is max" & "Second is Stapedial" =)
