Q

explain how you would palpate the trachea

A

before examining the patient, warn them that this can be uncomfortable

ask the patient to lean back (lower their neck slightly so their neck is relaxed)

place forefinger of your right hand at the suprasternal notch of the patient and push to upwards and backwards until the trachea is felt

= if trachea is in the midline then finger will not be able to progress further

excessive air | e.g. percussing puffed up cheeks
27
describe how lung percussion is carried out
percuss anteriorly: both apices, infraclavicular regions, 3rd, 5th and 7th intercostal spaces on both LEFT and RIGHT + right mid-axillary line percuss posteriorly: level of trapezius, level of scapular spine, 10th and 11th rib levels and laterally on right and left
28

pneumothorax hollow bowels COPD
29

pleural effusion (stoney dull) lung tumour (flat dull) consolidation (flat dull) lung collapse (flat dull)
30
which areas must lung percussion include?
apices of the lungs base of the lungs
31
what is auscultation?
listening to the lung sounds using a stethoscope
32
why are lung sounds heard?
due to air turbulence within the airways
33
what are the two types of normal lung sounds?
bronchial sounds | vesicular sounds
34
what are bronchial lung sounds?
high pitched notes
35
where are bronchial lung sounds heard?
anteriorly - normally heard over trachea, suprasternal notch, manubrium, sternal angle, and sternoclavicular joints (where alveolar tissue is absent) posteriorly - between C7 and T3
36
what are vesicular lung sounds?
low pitched notes
37
where are vesicular lung sounds heard?
normally heard over the rest of the chest area (where normal lung tissue is present)
38
describe and explain the difference between bronchial and vesicular lung sounds
bronchial sounds are from airways that are not surrounded by alvoelar tissue so the air turbulence can be heard unfiltered = HIGH PITCHED however vesicular sounds are from alveolar tissue which filters the sounds of air turbulence = LOW PITCHED
39
explain how lung auscultation is carried out
lie at 45 degrees, exposed from the waist up use the diaphragm to auscultate most areas of the chest, except the supraclavicular apical auscultation for which you will use the bell auscultate for bronchial breathing (!cannot auscultate over breast tissue!) compare results both anterior and posterior
40
in which locations is the lung auscultated on the anterior chest wall?
supraclavicular (bell) infraclavicular/2nd ICS (diaphragm) 3rd ICS (diaphragm) 6th ICS (diaphragm) AXILLAE (!!)
41
in which locations is the lung auscultated on the posterior chest wall?
level of trapezius level of scapular spine level of the 10th and 11th rib AXILLAE (!!) - only left
42
what must you remember when auscultating the lungs in females?
must not auscultate over the breast tissue
43
where is the apex of the lung auscultated?
supraclavicular region using the bell of the stethoscope
44
where is the superior lobe of the lung auscultated?
2nd ICS
45
where is the middle lobe of the lung auscultated?
4th ICS (just under the right axilla!) = as middle lobe only present on right side
46
where is the inferior lobe of the lung auscultated?
6th ICS
47
what can you do if breath sounds are inaudible?
ask the patient to take deep breaths in and out
48
where are the inspiratory and expiratory components of VESICULAR breath sounds produced?
inspiratory = lobar & segmental airways expiratory = central airways
49
describe the characteristics of vesicular breath sounds
low pitched length, intensity and pitch of inspiratory phase > expiratory phase no pause bw inspiration and expiration
50
give causes of the reduced intensity of vesicular breath sounds
shallow breathing airway obstruction hyperinflation pneumothorax pleural effusion pleural thickening obesity (i.e. if there is poor air generation in the airways or sound transmission through the tissues)
51
describe the characteristics of bronchial breath sounds
high pitched, hollow expiratory phase > inspiratory phase distinct pause bw inspiration and expiration
52
which pathologies are bronchial breath sounds heard over?
consolidation localised pulmonary fibrosis pleural effusion collapsed lung
53
when can the expiration phase become prolonged?
in obstructive lung disease e.g. asthma or chronic bronchitis
54
what is tactile vocal fremitus?
vibration of the chest wall during vocal sound
55
why does tactile vocal fremitus occur?
transmits from the larynx down the bronchial tree and into the chest wall
56
explain how tactile vocal fremitus is assessed
ask the patient to say ‘ninety-nine’ palpate across the posterior chest wall with your hands for changes in intensity you should feel the vibrations equally in both hands !! both posterior and anterior chest wall !!
57
what are the possible causes of decreased tactile vocal fremitus?
pneumothorax, COPD | due to decrease in density = increased/excessive air in lungs
58
what are the possible causes of increased tactile vocal fremitus?
consolidation in pneumonia tumour tissue in cancer (due to increase in density = replacement of air with another substance)
59
why is decreased tactile vocal fremitus caused?
decrease in density caused by an increase in distance between the chest wall and lungs (e.g. in pleural effusion due to fluid)
60
how are the cervical lymoh nodes palpated?
position the patient sitting and examine from behind use both hands to examine the lymph nodes on each side simultaneously use the pads of the fingers in a circular motion palpate across all the cervical lymph node groups, without lifting the fingers until the end
61
what is the order of cervical node palpation?
submental nodes – inferior to the chin submandibular nodes – inferior to the angle of the mandible preauricular/parotid nodes – anterior to the ear postauricular nodes – posterior to the ear occipital nods – base of the occipital superior deep cervical nodes – superior part of the sternocleidomastoid inferior deep cervical nodes – inferior part of the sternocleidomastoid supraclavicular nodes – superior to the clavicle
62
where are the submental nodes palpated?
inferior to the chin

superior to the clavicle
70
give four possible causes of cervical lymohedenopathy
lung cancer (metastasising to the lymph nodes) tuberculosis sarcoidosis respiratory tract infection
71
what is lung consolidation?
when air in the lungs is replaced by something else (e.g. inflammatory exudate, blood, pus, oedema)
72
what are the indications for a chest drain?
pleural effusion pneumothorax haemothorax
73
what is the most common position for chest drain insertion?
anterior to the mid-axillary line avoiding the long thoracic nerve lying behind the ‘safe triangle’
74
what are the four borders of the safe triangle for chest drain insertion?
posterior latissimus dorsi - posterior axillary fold anterior pectoralis major - anterior axillary fold inferior 5th intercostal space at mid-axillary line superior below apex of axilla
75
which ribs does the triangle of safety encompass?
overlies 2nd to 5th intercostal spaces
76
where can the needle be inserted for a chest drain?
once triangle of safety is marked out = needle may be inserted in the 2nd, 3rd, 4th and 5th intercostal spaces anterior to the mid-axillary line
77
why is the needle for a chest drain inserted in the upper border of the rib?
to avoid injuring the neurovascular bundle
78
what is the purpose of a chest drain?
the remove excess fluid/air from the pleural cavity
79
why is a tracheostomy performed?
to create an artificial air passage into the trachea
80
when is a tracheostomy performed?
upper airway obstruction respiratory failure
81
how is a tracheostomy performed?
opening is created on the anterior wall of the trachea between the 1st and 2nd tracheal cartilage rings infrahyoid muscle and thyorid isthmus retracted tracheostomy tube inserted and secured
