  • infraclavicular (below the clavicles)
  • interscapular (between the scapulae)
  • infrascapular (below the scapulae)
  • apices of the lungs (uppermost portions)
  • bases of the lungs (lowermost portions)
  • upper, middle, and lower lung fields
28
Q

Respiratory development during pregnancy

A
  • diaphragm elevated 4cm
  • decrease vertical diameter thoracic cage
  • increase horizontal diameter, increase tidal volume
29
Q

Infant respiratory development

A

body systems develop in utero; respiratory system alone does not function until birth

30
Q

Children respiratory development

A

respiratory development continues throughout childhood

31
Q

Developmental Considerations - older adults

A

less mobile thoracic cavity: calcified costal cartilages

decreased elastic properties within lungs (decreases recoil)

increase risk of pneumonia

32
Q

Developmental considerations

A

decreased number of alveoli - less surface area available for gas exchange

lung bases become less ventilated as a result of closing off a number of airways

33
Q

Focused questions to ask patients regarding shortness of breath (SOB) or dyspnea?

A
  • have you had any difficulty breathing

42
Q

Assessment of the lungs - survey respiration

A
  • rate, rhythm, depth, effort of breathing, signs of respiratory distress
  • describe size and shape of the chest
  • relate findings to landmarks
43
Q

Inspection (usually starting back working towards front)

A
  • symmetry, deformities
  • muscle retraction: intercostal spaces during inspiration
  • lag: delay
  • chest shape: normally wider than it is deep
  • AP diameter to the lateral chest (AP:L): 1:2 - increases with age
  • patient’s position
  • skin: cyanosis, pallor, clubbing of fingers
44
Q

Inspection: rate and rhythm of breathing

A

normal 10-20 breaths per minute, even pattern, normal depth (told us to stick with 10-20 for test)

tachypnea (>25 per minute; rapid, shallow)
bradypnea (<10 per minute)
apnea - periods of not breathing
hyperventilation (increase rate and depth)
hypoventilation (irregular shallow)
adventitious breath sounds

45
Q

Palpation

A

tenderness
intercostal tenderness: over inflamed pleurae
crepitus: fractures
bruising
sinus tract: inflammatory, tube-like structures opening onto the skin
chest expansion
tactile fremitus

46
Q

Palpation: how to assess chest expansion

A
  • place thumbs at level of 10th ribs with fingers loosely grasping and parallel to the lateral rib cage
  • position hands and slide them medially just enough to raise a loose fold of skin; thumbs over spine
  • ask patient to inhale deeply
  • watch the distance between your thumbs as they move apart during inspiration
  • feel for the range and symmetry of the rib cage as it expands and contracts
47
Q

Palpation: Assessing for Tactile Fremitus

A
  • assess for symmetry
  • use either the ball or ulnar surface of hand
  • ask the patient to repeat the words “99” or “one one one”
  • initially use for a side-by-side comparison
  • both hands to palpate and compare symmetric
  • identify and locate any areas of increased, decreased or absent fremitus

decreased/absent: voice is higher pitched or soft
– something obstructs the transmission of vibration
– COPD, pleural effusion, fibrosis, pneumothorax, infiltrating tumor, emphysema

increased
- compression or consolidation of lung tissue
- lobar pneumonia

48
Q

Palpation: tactile fremitus - crepitus

A

coarse, crackling over skin surface
subcutaneous emphysema - when air gets into tissue and can feel it; happens with chest tubes

assess:
temperature
lesions
masses
wounds

49
Q

Percussion - advanced assessment

A
  • producing audible sound and palpable vibrations
  • establish whether the underlying tissues are air-filled, fluid-filled, or consolidated

Normal: resonance
Abnormal: hyperresonance (COPD); dull (pneumonia)

50
Q

Auscultation

A

assessing air flow through the tracheobronchial tree

listening for:
- breath sounds
- adventitious (added) sounds
- abnormalities

diaphragm on chest wall

listen to one full respiration: inspiratory and expiratory, side to side
- C7-T10
- lateral from axilla to 7th rib

51
Q

Assessment of breath sounds (normal)

A

bronchial: over trachea and large bronchi; tubular sound, high pitched hollow sounds

bronchovesicular: medium- pitched sounds

vesicular: inspiration louder and longer than expiration, low pitched sounds

52
Q

Auscultation: adventitious breath sounds

A

added sounds: caused by moving air colliding with secretions in tracheobronchial passageways or by popping open of previously deflated airways

53
Q

Auscultation - adventitious breath sound type

A

crackles (rales)
wheezes
rhonchi
stridor
diminished/decreased, absent
pleural friction rub
abnormal vocal sounds

54
Q

What are crackles and types

A

discontinuous nonmusical, early inspiratory (COPD), late inspiratory (pulmonary fibrosis), or biphasic (pneumonia)

popping sound - inspiration; deflated - expiration

fine crackles
– softer, higher pitched, more frequent per breath than coarse crackles
– mid to late inspiration, dependent areas of the lung, varies with positioning –> fluid shifts

coarse crackles
– popping sound, are heard over any lung region, and do not vary with body position
– early inspiration and last throughout expiration

55
Q

Adventitious breath sounds - wheezes

A

continuous musical sounds, occur during rapid airflow when bronchial airways are narrowed
heard throughout the lung
inspiratory, expiratory, or biphasic
asthma, mucous plug, tumor

56
Q

Adventitious breath sounds - Rhonchi

A

variant of wheezes, same mechanism
lower in pitch
disappear with coughing

57
Q

Adventitious breath sounds - stridor

A

high-frequency, high-pitched musical sound produced during airflow through a narrowing in the upper respiratory tract

obstruction - foreign body

58
Q

Adventitious breath sounds - pleural friction rub

A

inflammation of the lung tissues
raspy breathing sounds

59
Q

Abnormal assessment findings

A

SOB or dyspnea

Cough
– mucus, pus, blood as well
– allergens: dust, foreign bodies, hot or cold air

Chest pain (CP) w/ breathing

Respiratory infection
– viral upper airway, bacterial infection
– pneumonia

Orthopnea - supine

Cheyne-Stokes respirations
– periods of deep breathing alternate with periods of apnea; severe state

Biot’s (ataxic) breathing
– severe; irregular Cheyne-Stokes
– periods of apnea alternate with regular deep breaths which stop suddenly for short intervals

Abnormal vocal sounds - advanced

60
Q

Abnormal vocal sounds (advanced assessment)

A

egophony, bronchophony, whispered pectoriloquy

61
Q

Anterior chest wall

A

shape, symmetry, configuration
facial expression
difficulty breathing
level of consciousness
color
quality of respirations
respiratory rate - 30s x 2
- w/ pulse ox

62
Q

Palpation - Anterior Chest Expansion

A
  • place thumbs along each costal margin and hands along the lateral rib cage
  • position your hands, slide them medially a bit to raise loose skin folds between your thumbs
  • ask the patient to inhale deeply
  • observe how far thumbs diverge as the thorax expands
  • feel for the extent and symmetry of respiratory movement
63
Q

Palpation: anterior tactile fremitus

A
  • begins over supraclavicular areas for apices (have patient say 99 or “one one one”)
  • compare both sides of the chest
  • use the ball or ulnar surface of the hand
  • fremitus is usually decreased or absent over the precordium
  • for woman, gently displace the breasts
64
Q

Percussion: anterior - advanced assessment

A
  • percuss the anterior and lateral chest, comparing both sides
  • the heart produces dullness to the left of the sternum from the 3rd to the 5th interspaces
  • gently displace the breasts for women
65
Q

Infant Auscultation

A
  • diaphragm is newborn’s major respiratory muscle
  • count respiratory rate for 1 full minute
  • normal rates 30-40 breaths (may spike up to 60)
  • most accurate respiratory rate when the infant is asleep
  • brief periods of apnea (less than 10-15 seconds) are common
    – is more common in premature infants
66
Q

Pediatric auscultation

A
  • bowel sounds are easily heard in the chest
  • use smaller pediatric diaphragm end piece, or place bell over infant’s interspaces and not over ribs
  • bronchovesicular breath sounds in peripheral lung fields of infant and young child up to ages 5-6 years
  • fine crackles are commonly heard in immediate new born period from opening of airways and clearing of fluids
67
Q

Older adults and illness

A

older adults:
- tire easily (don’t hyperventilate)
- increase AP diameter

illness:
- may need to roll from side to side
- limits comparison
