Pulmonary Edema X- Ray Findings

A - Alveolar edema (giving it a ground glass appearance)
B - Kerley B lines
C - Cardiomegaly
D - Upper lobe diversion ( increased blood vessels in upper lobe)
E - Enlarged hilar vessels giving a bat- wing appearance

Kronig's isthmus and Traube's space

Kronig's Isthmus is a band of resonance representing lung apex. It may also be remembered as the supraclavicular region.
Boundaries: Medially: Scalene
                    Laterally: Acromion process
                    Anteriorly: Clavicle
                    Posteriorly: Trapezius

Impaired dullness: Fibrosis, Upper Lobe Collapse and Mass
Hyperresonant: Emphysema, Hydropneumothorax

Traube's Space boundaries:
Superiorly: 6th rib
Laterally: Mid axillary line
Medially: Left costal margin

Dullness: Splenomegaly, Full stomach, Left Pleural Effusion, Carcinoma involving gastric fundus, Enlarged left lobe of liver, Achalasia cardia

Percussion myokymia

In a chronically wasted individual as in pulmonary tuberculosis, a percussion stroke close to sternum on the front of the chest, may cause a transient twitching of the muscle which is more marked on the side of the pulmoary affection.

Coin Test

Coin test:
Ask an assistant to put a coin on the anterior chest wall and strike the coin by another coin. Simultaneously auscultate using your stethoscope on the posterior chest wall. If you hear a bell like sound, it's due to pneumothorax.

Barrel Chest Anatomy/ Features

What are the features of a barrel shaped chest?

AP:Transverse :: 1:1

Anteriorly:

• Supraclavicular fossa is prominent
• Angle of Louis is prominent
• Cricosternal distance is reduced
• Obtuse subcostal angle  (due to horizontal placement of ribs)

Posteriorly: Kyphosis

Laterally:

• Ribs are horizontal
• Intercostal space widen
• Intercostal indrawing

Action speaks louder than words!
It takes a great deal to be an expert in anatomy. Tens and hundreds of pictures from all angles given in the book/ atlas can sometimes do nothing. So, here is a one stop website to learn basic anatomy and basic physiology of the respiratory system using animations.

Did you know just like an instagram for doctors, there is an youtube for medicos? And a kinda sorta wikipedia? Well, now you know!

Also, bookmark this. It contains some anatomy, histology and embryology.

This was in my drafts. Saved in November 2011. Posting it now for our new 1st and 2nd year medicos.
