Happy friday everyone!
We’ll learn about obstructive and restrictive lung diseases today.
This is just a short summary for a quick review :)

Obstructive lung diseases - Characterized by airway obstruction
Increased compliance - Due to the loss of alveolar and elastic tissue
You have a problem getting air out of your lungs
Mnemonic: Obstructive Out

They breathe like “poof poooooof”
In and oooooout
They take infinity to get it all out =P
So, FEV1 / FVC is decreased

TLC and RV increased - Flow volume loop shifts towards left

Examples: Any pathology that decreases the ability to develop a positive intrapleural pressure
Chronic bronchitis
Asthma
Bronchiectasis
Emphysema
COPD

Restrictive lung diseases - restriction of lung expansion
Reduced compliance - lungs become fibrotic, lose their distensibility and become stiffer
You have a problem getting air into your lungs
Mnemonic: Restrictive Reduced compliance

They breathe like “poof pof”
In and out
They get everything out in one second =P
So, FEV1 / FVC is increased

TLC and RV decreased - Flow volume loop shifts towards the right

Examples: Any pathology that decreases the ability to develop a negative intrapleural pressure
Pulmonary fibrosis
Asbestosis
Sarcoidosis
Pneumoconioses
Kyphoscoliosis
ARDS
Polio
Obesity

That’s all!

I know you must’ve found the “poof” sounds pretty weird because that isn’t the way you breathe
But they are a funny and they help me remember so I put it up anyway ^___^”
Just like “lup dubb” are official sounds for heart beats.. Which sounds would you assign to inspiration and expiration?

Relevant for physiology exam next week!
