Q

how would you prepare a patient for a resp exam after gaining consent?

A
  • Ask patient to undress down to waist behind curtain – can keep bra on, offer blanket

25
would do you look for at the neck within a resp exam?
JVP, heptajugular reflex, trachea deviation, cricosternal distance, neck lymph nodes
26
what would a raised JVP indicate?
cor pulmonale - right sided HF secondary to lung or pulmonary arterial disease >3cm is a concern
27
when would you do a hepatojuglar reflex?
in a healthy individual >4cm is a concern
28
how do you assess trachea deviation?
chin relaxed down - find lateral borders using three fingers
29
how do you measure crico-sterno distance ?
using three fingers (or patients own if difference in size) from sternal angel to start of cartilage
30
what would an extended cricosternal distance show?
hyperinflation eg COPD
31
how do you assess patients neck lymph nodes
stand behind sat down patient and feel along neck small pea like shape - inflamed
32
what do you assess within the chest section of resp exam?
inspection, palpitation, percussion, auscultation - quality of sounds, expansion
33
what do you do within the inspection part of chest resp exam?
scars and deformities
34
what would chest scars mean?
surgeries - CABG, VR, posterolateral/ thoracotomy
35
what would an asymmetric chest be a sign of?
pneumonectomy
36
what would a barrel chest - hyper expansion be casued be?
emphysema - COPD
37
what would right ventricular heave show?
visible or palpable - large pleural effusions
38
how do you assess chest expansion?
but thumbs iv V shape across midline and when patient breaths in and out - do they move same distance etc
39
what does symmetrically reduced chest expansion show?
idiopathic pulmonary fibrosis
40
what would unilaterally reduced chest expansion show?
pneumothorax
41
how would you check percussion of chest?
non dominant hand on chest wall, middle finger pressed against chest wall and briskly strike finger supraclavicular, chest wall x4 bilaterally, and to axilla
42
what would air sound like when percussing?
loud high pitched, high resonance
43
what would a solid structure sound like durng percussion?
dull low pitched
44
what would a hyper-resonant percussion suggest?
pneumothorax
45
what do you assess when hearing sounds during auscultation?
volume of sound quality (normal vs not) added sounds
46
when would the volume of auscultation be quieter?
pneumothorax/ pleural effusion - liquid/ air blocking normal movements
47
what type of sounds can be added and essentially abnormal?
wheeze, coarse, stridor, crackles
48
what would a wheeze indicate?
bronchoconstriction
49
what would coarse - brief crackles indicate?
pneumonia
50
what do crackles represent within ausculatation?
interstitial lung disease
51
what you check for on legs section within resp exam?
pitting oedema signs of DVT
52
how would you conclude and finish a resp exam?
- Thank patient - Cover them up with blanket/ sheet – allow time to for them to redress - Wash hands - Summarise findings - Suggest further assessments and investigations (usually 3) eg sputum sample, peak expiratory flow rate, CXR, ECG
53
what is arterial blood gases used for?
diagnostic tool - Used in emergency, intensivist, anaesthesiology and pulmonary medicine - Alveolar-arterial oxygen gradient is useful measure of lung gas exchange – can be abnormal in patients with ventilation-perfusion mismatch
54
is ABG quicker than FBC for electrolyte counts?
yes - takes minutes whereas FBC can take an hour
55
what is the main focus of ABG?
Respiratory gas exchange, acid- base balance
56
how can lactic acid build up?
Insufficient O2 delivery to mitochondria leads to anaerobic respiration which produces less ATP and lots of lactic acid
57
what is type I resp failure?
- Type I: low oxygen cell death due to hypoxia. Aetiology: shunt (pneumonia), diffusional (COVID), V/Q mismatch (PE), ventilation (coma) and altitude. - MORE SEVERE
58
what is type II resp failure?
- Type II: high carbon dioxide and can have lower oxygen as a result – cell death due to acidaemia
59
what is the partial pressure of oxygen in room air?
21kPa - like the gas % of air
60
what type of oxygen should you use when measuring ABG and why?
room air venturis - know percentage by colour so can compare
61
how much oxygen does a rebreather oxygen mask give?
percentage is unknown but allows for continuous rapid oxygen - 15L - good in emergency medicine
62
why is having unnecessary high FiO2 bad?
can causing wasting in lungs and respiratory depression - no need to breathe
63
in COPD patients do they respond to CO2 like normal physiology?
no as used to chronic CO2 exposure - more likely to respond to hypoxaemia
64
what is optimal pH?
7.35-7.45
65
what can acidaemia cause?
myocardial suppression/ arrhythmias, cell death, enzyme dysfunction, excitable tissue, hyperkalaemia
66
what can alkalaemia cause?
enzyme dysfunction, poor oxygen uptake by tissues, cell death
