Lecture 20 - Review Flashcards
Label the lung image 1:
1 = apex
2 = medial surface
3 = base
4 = diaphragmatic surface
5 = costal surface
6 = cardiac notch
How can you tell what are the airways in the lung hilum?
Airway = cartilage
What condition can you hear changes in apical lung sounds?
TB
Pancoast tumours?
What forms the costodiaphragmatic recesses?
Parietal pleura extends further down into the chest compared to the visceral pleura
What can accumulate in the costodiaphragmatic recesses?
What is this called?
Pleural fluid
Pleural effusion
Why is a normal relationship between the pleural layers essential for normal lung function?
The pressure in the intrapleural space should be maintained as negative with pleural fluid between them
It allows for both the chest and the lungs to expand or shrink simultaneously
Slide 5:
Which pressure is represented by the area shaheed in pink?
Intrapleural pressure
What statement describes trans pulmonary pressure on slide 8?
The difference between the intrapulmonary pressure and intrapleural pressure
What is intrapulmonary pressure?
Pressure within the alveoli
Look t slide 9:
Diagnose the most likely cause of the mans illness and why?
TB
Affecting apical portion of lungs (TB preferentially infects the well aerated areas of the lungs
Fever
Fatigue
Poor. Living conditions
If you suspect TB infection, what diagnostic approach is most appropriate:
Slide 11:
Obtain 3 sputum samples for acid fast bacilli smear microscopy and culture
What i s the point of an interferon gamma release assay?
Says whether the individual has been previously exposed to TB
What is primary TB?
Patient exposed to Tb and suffers symtpoms
What is latent TB?
When the infection is contained and isn’t symptomatic
What is post primary TB?
When latent TB becomes reactivated
