Q

What general signs are you looking for?

A
  • Age (for younger = asthma/CF. older = COPD or malignancy)
  • Cyanosis (peripheral vasoconstriction due to hypovolaemia)
  • SOB
  • Cough
  • wheeze
  • Stridor
  • Pallor (underlying anaemia)
  • oedema (pedal or ascites both associated with right ventricular failure) Pulmonary oedema is left ventricular failure
  • cachexia (malignancy or COPD)

Q

How to measure Jugular Venous Pressure?

A

Bed at 45 with patient looking left. Look at IJV between medial end of clavicle and er lobe under medial aspect of SCM. Double wave pulsation to differentiate against single of carotid artery. Measure highest point of pulse to sternal angle. No greater than 3cm in normal people

Also check the hepatojugular reflux test

Q

Causes of raised JVP?

A

This is venous hypertension caused by pulonary hypertension (right side heart failure from COPD). other cardio causes include congestive heart failure, tricuspid regurgitation and constrictive pericarditis

Q

What facial features are we inspecting for?

A

Plethoric Complication (red faced appearance associated with polycythaemia e.g. COPD, and T2RF.

Eyes: Conjunctival Pallor (anaemia) and ptosis, miosis and enopthalmos (from horners syndrome. Can be lung cancer e.g. pancoast tumour)

Mouth : central cyanosis and oral candidiasis (from steroid inhaler use)

Q

Chest inspection Scars?

A

Median sternotomy = CABG and cardiac valve replacement
axillary thoracotomy = Insertion of chest drain
Posterolateral thoracotomy = (scapula and mid-spinal line). used for lobectomy, pneuonectomy and oesaphageal surgery
Infraclavicular scar = pacemaker insertion

17
Q

What radiotherapy associated skin changes may you see?

A

Xerosis, hyperkeratosis, scale, depigmentation and telangiectasia

18
Q

What chest wall deformities may be present?

A

Pecus carnitus or excavatum. Asymmetry (pneumonectomy or thoracoplasty (TB)
Hyperexpansion (barrel chest from COPD

19
Q

Airway Test?

A

Assess tracheal position and crciosternal distance. This distance should be inferior border of cricoid cartilage to the suprasternal notch. Shoould be 3-4 fingers

20
Q

Causes of tracheal deviation and abnormal cricosternal distance?

A

Trachea deviates away from tension pneumothorax and large pleural effusion and towards lobar collapse and pneumonectomy.

<3 finger distance = lung hyperinflation (e.g. asthma and COPD)

21
Q

What Chest features for palpation?

A

Palpate apex beat in 5th ICS at MCL.

Assess chest expansion.

22
Q

Resp causes of displaced apex beat?

A

Right ventricular hypertrophy from pulmonary hypertension, COPD and interstitial lung disease. large pleural effusion and tension pneumothorax

23
Q

Causes of reduced chest expansion?

A 
Symmetrical = pulmonary fibrosis
Asymmetrical = pneumotroax, pleural effusion andf pneumonia
24
Q

What areas for percussion?

A

Supraclavicular for lung apices, infraclavicular, chest wall 3-4 locations bilaterally and axilla

25
Q

What percussion notes are there>

A

Resonant, dull (density from lobar collapse, consolidation and tumour), stony dullness (pleural effusion). Hyper-resonance (pneumothorax)

26
Q

How to test for tactile vocal fremitus?

A

Ask the patient to repeatedly say 99 and palpate areas of the chest.Increased vibration = consolidation, tumour, lobar collapse. Decreased = pleural effusion, pneumothorax

27
Q

Different quality of breath sounds?

A 
Vesicular = normal
Bronchial = harsh sounding with pause between inspiration and expiration.
28
Q

List the lymph nodes that need to be palpated?

A

Submental, submandibular, pre-auricular, post-auricular, superficial cervical deep cervical, posterior cervical, supraclavicular and in particualr Virchows nodes

29
Q

What is Virchows node associated with?

A

Upper GI malignancy

30
Q

What are resp causes of lymphadenopathy?

A

Lung cancer with metastases, TB and sarcoidosis

31
Q

What are final exam steps?

A

Check for sacral and pedal oedema (congestive heart failure). Assess the calves for DVT and signs of saphenous vein harvesting. Check for erytherma nodosum for sarcoidosis

32
Q

How to complete the exam>

A

Thank patient and ask if they need any help putting clothes back on. Dispsoe of PPE, Summarise.

33
Q

What further assessments may you do?

A

Check O2 sat and other vitals, sputum sample, peak flow assessment, chest xray, ABG and full cardio exam if indication
