Q

describe wheeze

A

polyphonic wheeze in expiration; asthma, COPD

focal monophonic wheeze; localised area of large airway narrowing caused by foreign body or tumour

19
Q

describe crackles

A

early inspiratory crackles; chronic bronchitis, emphysema

late inspiratory crackles; base of lung, fibrosing alveolitis, pulmonary oedema

20
Q

what are the components of peak flow?

A

attach mouth piece
ensure peak flow is set to 0
ask patient to stand and hold meter horizontal
take a deep breath in and make a tight seal with their lips around the mouth piece
blow out as hard and as fast as they can; a fast blast is better than a slow blow
note the number where the sliding pointer has stopped on the scale
repeat x 3
record highest value in L/min

21
Q

describe the different types of inhaler

A

reliever; salbutamol
preventer; beclamethasone
SMART; Symbicort, both reliever and preventer
advise them to wash out their mouth after each use; oral candidiasis, side effects if contain steroids

22
Q

what things should you advise a patient to do before they use their inhaler?

A

device test; if it hasn’t been used for >5 days, remove the cap, shake the inhaler, release a puff into the air
check the dose counter if present
check the expiry date

23
Q

describe the procedure of using an inhaler

A

hold upright
remove the cap and inspect
shake well
sit/stand upright and tilt chin up slightly
breathe out gently and slowly away from the inhaler
put your lips around the mouthpiece, creating a tight seal
breathe in slowly and press the canister once
continue to breath in slowly until lungs feel full
remove inhaler and seal your lips
hold your breath for 10 seconds
breath out gently
replace the cap
rinse mouth with water

second puff; wait 30 seconds and repeat

assess the patients technique

24
Q

describe the procedure of using a spacer

A

prepare the inhaler as previous
attach the inhaler mouthpiece to the spacer
breathe out gently and slowly away from the spacer until your lungs feel empty
place your lips around the spacer to create a tight seal
release one dose of the inhaler into the spacer device
breathe deeply, in and out, through the spacer mouthpiece
administer a second dose if required

25
Q

what are the care instructions required for spacers?

A

washed with detergent/washing up liquid 1x month and left to air dry
never wiped dry; static causes drug particles to stick
replaced 1x year

26
Q

describe nasal cannula

A

24-30%
comfortable
non-acute ward use, if mildly hypoxic

27
Q

describe Hudson mask

A

30-40%

step up from nasal cannula

28
Q

describe venturi mask

A 
often used in COPD
blue; 2-4L/min
white; 4-6L/min
yellow; 8-10L/min
red; 10-12L/min
green; 12-15L/min
29
Q

describe non-rebreather mask

A

85-90% with 15L flow rate
bag with valves stopping almost all rebreathing
acutely unwell patients

Q

describe non-invasive ventilation (CPAP/BiPAP)

A

continuous positive airway pressure; keeps airways open in sleep apnoea or heart failure
bilevel positive airway pressure; used in COPD and atelectasis

31
Q

describe invasive ventilation

A

ventilation bag/machine is attached to an artificial airway to ventilation lungs
used in intensive care and theatre

32
Q

when should a patient be ventilated?

A

GCS 8 or less

33
Q

what are the aims of oxygen saturation?

A

94-98% in normal patients

88-92% in COPD

34
Q

how is chest x-ray image quality assessed?

A

rotation; medial aspect of each clavicle should be equidistant from the spinous processes
inspiration; 5-6 anterior ribs, lung apiece, costophrenic angles and lateral ribs visible
projection; AP or PA
exposure; left hemidiaphragm should be visible to the spine and the vertebrae should be visible behind the heart

35
Q

what do you look for in the airway part of the chest x-ray?

A

trachea; deviation
carina
bronchi
hilar structures

36
Q

what are the causes of tracheal deviation?

A

true;
pushing; large pleural effusion or tension pneumothorax
pulling; consolidation associated with lobar collapse
apparent; rotation of the patient

37
Q

what are the causes of hilar enlargement/abnormalities?

A

bilateral symmetrical enlargement; sarcoidosis
unilateral/asymmetrical enlargement; malignancy
pushed; enlarging soft tissue mass
pulled; lobar collapse

38
Q

what do you look for in the breathing part of the chest x-ray?

A

lungs

pleura; hydrothorax, haemothorax, mesothelioma

39
Q

what do you look for in the cardiac part of the chest x-ray?

A

heart

heart borders; right atrium and left ventricle

40
Q

what do you look for in the diaphragm part of the chest x-ray?

A

pneumoperitoneum; free gas under the diaphragm (bowel perforation)
pseudopneumoperitoneum; false impression of free gas under the diaphragm (Chilaiditi syndrome)
costophrenic angles; lost with fluid or consolidation

41
Q

what do you look for in the everything else part of the chest x-ray?

A

mediastinal contours; aortic knuckle, aorto-pulmonary window
bones
soft tissues
tubes, lines, valves and pacemakers

42
Q

what are the review areas of the chest x-ray?

A 
lung apices
retrocardial
behind the diaphragm
peripheral region of the lungs
hilar region
43
