Examination of the respiratory system Flashcards
what angle should the patient be at?
45 degrees
key elements of the general inspection?
bed side-oxygen/nebuliser/sputum cup
patient- accessory muscles/ distressed/LOC
noises- wheeze/hoarse voice/stridor
what does a wheeze indicate?
COPD
asthma
what does stridor indicate (rasping noise on inspiration)
obstruction of airways
normal angle between nail and cuticle ?
140 degrees
common causes of finger clubbing
intrathoracic disease eg fibrosis, empyema. bronchiectasis,lung cancer
what to observe for in the hands?
nicotine staining peripheral cyanposis finger clubbing small muscle wasting tremor co2 retention flap pulse resp rate
what may cause muscle wasting?
compression of the brachial plexus by peripheral lung tumours
what does a fine tremor indicate
beta 2 adrenoceptor agonist
eg salbutamol inhaler
extending wrists with eyes closed tests for what
checks for co2 retention flap
what does increased pulse volume indicate?
co2 retention
what does tachycardia indicate?
severe asthma
normal respiratory rate
12-20 per minute
inspection of face and neck
central cyanosis
anaemia in conjuctiva
JVP -elevated? pulsatile?
pale conjunctiva indicates what?
anaemia
patient with general cyanosis and warm extremities. what is the likley cause?
venous/arterial shunts
what can cause central cyanosis
lung disease
what would cause a non pulsatile JVP
obstruction in SVC due to tumour in mediastinum
what to look for in chest inspection
pectus excavatum pectus carinatum scoliosis over expanded scars
what is palpated ?
trachea
apex beat
chest expansion
what could cause tracheal deviation
towards lesion- fibrosis, pneumonetomy
away from lesion- massive plural effusion, pneumothorax
what does reduced expansion on one side of the chest indicate
lesion on that side
where should chest expansion be checked
2x front
1x back
where should percussion be done ?
middle phalanx of middle finger using other middle finger
what position should the patient be in when percussing the back?
arms forward
normal chest percussion sound
resonant
what does a dull percussion indicate?
consolidated lung
what does a stony dull percussion note indicate?
fluid filled area eg pleural effusion
what does a hyper resonant percussion sound indicate?
percussion over a hollow structure eg.pneumothorax
what should the patient do during auscultation
breathe in and out through an open mouth every time stethoscope moved
what side of the stethoscope should be used
diaphragm
how are normal breath sounds described
vesicular
what sound is described as vesicular?
breath sound increase in intensity in inspiration and fading in expiration
what due bronchial breath sounds indicate?
consolidation /fibrosis
what are the three ways the intensity of breath sounds can be described
normal
reduced
abscent
locally abscent breath sounds can indicate
pneumothorax
pleural effusion
what 3 sounds may be audible as added sounds?
wheeze
crepitations
pleural rub
