T4 Spinous Process
25
Pursed lip
COPD
Creates pressure and keeps airways open

Seen in Difficulty of Breathing, widened nostrils for air seen in infants
Nasal flaring

chronic finding
28
Accessory muscles of breathing:
sternocleidomastoid
scalene
serratus anterior
29
Anteroposterior diameter is increased due to air trapping
Seen in COPD patients
AP>Transverse diameter
Barrel Chest
30
structural deformity of the anterior thoracic wall in which the sternum and rib cage are shaped abnormally
This produces a caved-in or sunken appearance of the chest.
Pectus Excavatum
31
“pigeon chest”
Protrusion of the sternum and ribs
Pectus Carinatum
32
Configuration in whch one chest wall moves paradoxically inward during inspiration
Seen in 2-point fracture of the same rib
Distal and proximal ends of the rib
trauma
Flail Chest
Why? Inspiration – negative pressure – sucks flail segment out
Expiration – positive pressure – flail segment pushed out
33
Is it okay to ask the patient to breathe normally?
Never ask the patient to breathe “normally”
Patient becomes anxious or conscious, thus voluntarily change their breathing patterns and rates
A better way is to direct your eyes to the patient’s chest after taking the radial pulse
34
Seen in exercise, anxiety, and metabolic acidosis
Rapid Deep Breathing (Hyperpnea, Hyperventilation)
35
is deep breathing due to metabolic acidosis. It may be fast, normal, or slow
Kussmaul breathing
36
What to consider in Rapid Deep Breathing (Hyperpnea, Hyperventilation)?
Consider infarction, hypoxia, or hypoglycemia
37
Mechanism of Rapid Deep Breathing (Hyperpnea, Hyperventilation) in renal failure?
Usually in renal failure -> decrease in plasma bicarbonate -> acidosis -> compensatory increase in ventilation mitigates the fall in systemic pH -> blow off co2
38
An oscillation of ventilation between apnea and hyperpnea with a crescendo-decrescendo pattern
Periods of deep breathing alternate with periods of apnea (no breathing)
Associated with changing serum partial pressures of oxygen and carbon dioxide
Brain tumor, stroke
Pons
Cheyne-Stokes Breathing
39
Seen in brain tumors, stroke -> affected respiratory centers
Cheyne-Stokes Breathing
40
Begins with hyperventilation -> blow of CO2 -> triggers apnea ->Rise in CO2 -> hyperventilation recurs -> cycle repeats
Cheyne-Stokes Breathing
41
Characterized by unpredictable irregularity
Breaths may be shallow or deep, and stop for short periods
Causes: respiratory depression and brain damage typically at the medullary level
Most commonly seen in meningitis
Biot’s Breathing (Ataxic Breathing)
42
used to assess patients with CNS depression
Cheyn Stokes and Biots
43
– Medulla
Biots
44
– Pons
Cheyn Stokes
45
- Rapid Gasping + apnea
Biot’s
46
- Increase and Decrease + Apnea
Cheyn Stoke’s
47
“chest pain” may musculoskeletal –
costochondritis
48
How to do Chest Lag Test for Lung Excursion?
Place your thumbs at about the level of the 10th ribs, with fingers loosely grasping and parallel to the lateral rib cage
Slide your hands slightly medially just enough to raise a loose fold of skin
Ask the patient to inhale deeply
Watch the distance between your thumbs as they move apart
Check for symmetry
Localized pulmonary disease may cause one side of the chest to move less than the opposite
49
palpable vibrations transmitted through the bronchopulmonary tree to the chest wall as the patient speaks
Fremitus

Use the _____ surface of the hand in palpating fremitus
ulnar
51
Locations of palpating fremitus
Image
52
Transmission of fremitus is increased in what conditions?
in conditions that increase the density of the lung
Consolidation
Mass
53
Fremitus is decreased as it travels through liquid or air:
| Examples of conditions-----
Pneumothorax
| Pleural effusion
54
sound travels faster in what medium?
sound travels faster through solid
55
Percussion Penetrates only up to ____cm
5cm to 7cm
56
How to perform percussion?
Hyperextend the middle finger of your left hand (pleximieter finger)
Press its distal interphalangeal joint firmly on the surface to be percussed
Other fingers should not be touching the chest
With a quick, sharp but relaxed wrist motion, strike the pleximeter finger with the right middle finger (plexor finger)
Strike using the tip of the plexor, not the finger pad
57

replaces resonance when fluid or solid tissue replaces air-containing lung or occupies the pleural space
Dullness
64

69
How to check for Descent of Diaphragm (Diaphragmatic Excursion)?
Hold the pleximeter finger above and parallel to the expected level of dullness
Percuss downward until dullness clearly replaces resonance
70
An abnormally high level of diaphragm suggests?
pleural effusion, or a high diaphragm as in phrenic nerve paralysis
71
Pattern of auscultation
Image
72
The most important examination technique for assessing air flow through the tracheobronchial tree
Auscultation
73
Breath sounds:
Vesicular
Bronchovesicular
Bronchial
74
Adventitious breath sounds:
Crackles
Wheezes
rhonchi
75
Soft, low pitched sounds heard over most of the lung field
Produced by air moving through the small bronchioles and alveoli
Inspiratory component is much longer than the expiratory component
Vesicular
76
Mixture of bronchial and vesicular sounds
Inspiratory and expiratory components are equal in length
Normally heard in the first and second interspaces anteriorly, and between the scapulae posteriorly (mainstem bronchi)
Bronchovesicular
77
Loud, high pitched, and sound like air rushing through a tube
Expiratory component is louder and longer than the inspiratory component
Normally heard over the manubrium (over the trachea)
Bronchial
78
Harsh, loud, high-pitched sounds heard over the extrathoracic trachea
Inspiratory and expiratory components are approximately equal
Tracheal
79
Short, discontinuous, nonmusical sounds heard mostly during inspiration
Caused by opening or expansion of collapsed distal airways and alveoli due to secretions
“Rubbing hair next to ear”
Crackles/Rales or crepitation
80
Inspiratory phase
High pitch
hair
Fine:
81
Both phases
Low pitch
bubble
Coarse:
82
Continous, high-pitched sounds heard mostly during expiration
Produced by turbulent airflow through narrowed bronchi
Swelling, secretions, tumor, foreign body
Bronchospasm of asthma
Wheeze
83
Can wheezing be both inspiratory and expiratory?
Can be both inspiratory and expiratory - worse
84
Lower pitched, more sonorous lung sounds
“snoring” quality
More common with transient mucus plugging and poor movement of airways
Rhonchi
85
Low pitch and continuous (insp/exp) compared to wheezing
Occurs when air passes through large airways filled with secretions -> turbulent fow
Cleared with coughing (secretions)
Rhonchi
86
Grating sound produced by motion of pleura, which is impeded by frictional resistance
When pleural surfaces are roughened or thickened
Pleuritis/pleurisy
Best heard: end of inspiration and beginning of expiration
Creaking leather
Pleural Rub
87
Mechanism:
| Crackles
Alveolar secretions
88

Airflow through obstructed airway
| “whistle”
89
Mechanism:

| Turbulent flow through large airway secretions

92
Causes:
| Wheeze
Asthma
| Bronchitis
93
Causes:
| Rhonchi
Bronchitis
94
Causes:
| Pleural Rub
Pleuritis, Pneumonia
95
Is an increased resonance of voice sounds
Enhanced transmission of high-frequency sound across fluid
Caused by consolidation, pleural effusion and fibrosis
E to A transition
Egophony
96
Intensification of the whispered word heard
Instruct the patient to whisper “one two three”, while examiner listen to the area suspected of consolidation
Normally, whispering produces high-pitched sounds that are filtered out by the lungs, so nothing is heard
If consolidation is present, whispered words are louder and clearer
Whispered Pectoriloquy
97
Increased transmission of spoken words heard in the presence of consolidation of the lungs
Says “ninety-nine”, while the examiner listens
If bronchophony is present, words are transmitted more loudly than normally
Bronchophony or “Tactile Fremitus”
98
Same as whispered pectoriloquy, but spoken instead of whispered
Bronchophony or “Tactile Fremitus”
99
Inreased vocal fremitus =
increased tactile fremitus also
