Q

symmetric expansion

A

-Confirm symmetric chest expansion by placing your warmed hands on the posterolateral chest wall with thumbs at the level of T9 or T10.
-Slide your hands medially to pinch up a small fold of skin between your thumbs Ask the person to take a deep breath.
-Your hands serve as mechanical amplifiers; as the person inhales deeply, your thumbs should move apart symmetrically. Note any lag in expansion.

Q

how do you palpate for tactile fremitus

A

Use palmar base (ball) of fingers or ulnar edge of one hand
-touch person’s chest while he or she repeats words, “ninety-nine” or “blue moon.”
-Start over lung apices and palpate from one side to another
-symmetry is most important; vibrations should feel same on each side.
o-avoid palpating over scapulae because bone damps out sound transmission.

25
While standing behind person, listen to following lung areas:
o Posterior from apices at C7 to bases around T10 o Laterally from axilla down to seventh or eighth rib
26
what three types of normal breath sounds should you expect to hear in adult and older child.
-Bronchial -Bronchovesicular -Vesicular
27
bronchial breath sounds
loud, high-pitched, hollow sounds
28
Where are bronchial breath sounds heard?
trachea and larynx
29
bronchovesicular breath sounds
medium-pitched and quieter sounds
30
where are bronchovesticular breath sounds heard?
Over major bronchi where fewer alveoli are located: posterior, between scapulae especially on right; anterior, around upper sternum in 1st and 2nd intercostal spaces
31
vesicular breath sounds
soft, fine, breezy, low-pitched sounds
32
where are vesicular breath sounds heard?
Over the peripheral lung fields
33
adventitious sounds
Added sounds that are not normally heard in lungs
34
adventitious sounds are caused by
moving air colliding with secretions in tracheobronchial passageways or by popping open of previously deflated airways
35
adventitious sounds:classification and nomenclature of these sounds
crackles (or rales) and wheeze (or rhonchi) are terms commonly used by most examiners.
36
Atelectatic crackles
a type of adventitious sound, is not pathologic; short, popping, crackling sounds that sound like fine crackles but do not last beyond a few breaths
37
wheezes
Rhonchi
38
crackles
rales
39
Where are atelectatic crackles heard?
heard in the periphery only, and disappear after first few breaths or after a cough
40
While ausculating voice sounds, Ask person to repeat what phrase while you listen over chest wall?
"ninety-nine"
41
what do you normally hear while ausculating voice sounds
Normal voice transmission is soft, muffled, and indistinct; you can hear sound through stethoscope but cannot distinguish exactly what is being said.
42
when ausculatating breath sounds, Progress from side to side as you move downward, and...
listen to one full respiration in each location.
43
Auscultate lung fields over the
anterior chest from apices in supraclavicular areas down to sixth rib.
44
A healthy person with no lung disease and no anemia normally has an SpO2 of
97% to 98%. >95% is good
45
what is a safer, simple, inexpensive, clinical measure of functional status in aging adults.
The 6-minute walk test (6 MWT)- checks if they are havinf SOB, whats their pulse ox?
46
developmental competence of againg adult
o round barrel shape, and kyphosis or an outward curvature of thoracic spine. o Chest expansion may be somewhat decreased, although still symmetric. o Tend to tire easily during auscultation when deep mouth breathing is required
47
thoracic diameter and barrel chest
shows an increased anteroposterior diameter
48
developmental competence of acutely ill patient
-Use of a second examiner to assist the patient in terms of positional changes -If no one is available, examiner may roll patient from side to side to facilitate change of position. -If rolling technique is used, this may interfere with bilateral assessments of inspection and percussion.
49
crepitus
crackling, crinkling, grating feeling under the skin (Rice crispies)
50
Barrel chest
a condition characterized by increased anterior-posterior chest diameter caused by increased functional residual capacity due to air trapping from small airway collapse. A barrel chest is frequently seen in patients with chronic obstructive diseases, such as chronic bronchitis and emphysema.
51
thorax and lung exam: inspection
Thoracic cage, respirations, skin color, and condition o Person's facial expression, and LOC
52
thorax and lung exam: palpation
o Confirm symmetric expansion and tactile fremitus. o Detection of any lumps, masses, or tenderness
53
thorax and lung exam: auscultation
o Assess breath sounds, and note any abnormal/adventitious breath sounds.
54
Pectus excavatum
sunken sternum and adjacent cartilages
55
Pectus carinatum
a chest that protrudes like the keel of a ship
56
Scoliosis
abnormal lateral curvature of the spine
57
Kyphosis
hunchback
58
Sigh
o Occasional sighs punctuate the normal breathing pattern and are purposeful to expand alveoli. Frequent signs may indicate emotional dysfunction and also may lead to hyperventilation and dizziness.
59
Tachypnea
Rapid, shallow breathing. Increase rate.
60
Bradypnea
o Slow breathing. A decreased but regular rate .
61
Hyperventilation
Increase both rate and depth. Blows off CO2, causing decrease in the blood
62
Hypoventilation
ventilation of the lungs that does not fulfill the body's gas exchange needs; An irregular shallow pattern
63
Cheyne-Stokes respiration
A cycle in which respirations gradually wax and wane in a regular pattern, increasing in rate and depth and then decreasing. The breathing periods last 30 to 45 seconds, with periods of apnea (20 seconds) alternating the cycle
64
Biot's respiration
Similar to Cheyne-Stokes respiration, except that the pattern is irregular. A series of normal respirations (3 to 4) is followed by a period of apnea. The cycle length is variable, lasting anywhere from 10 seconds to 1 minute.
65
Chronic obstructive breathing
normal inspiration and prolonged expiration to overcome increased airway resistance
66
Discontinuous sounds
o Crackles—fine o Crackles—course o Atelectatic crackles o Pleural friction rub
67
Continuous sounds
o Wheeze—sibilant o Wheeze—sonorous rhonchi o Stridor
68
Crackles—fine
Discontinuous, high-pitched, short, crackling, popping sounds heard during inspiration that are not cleared by coughing.
69
Crackles—course
Loud, low-pitch bubbling and gurgling sounds that start in early inspiration and may be present in expiration.
70
Pleural friction rub
A very superficial sound that is coarse and low pitched; it has a grating quality as if two pieces of leather are being rubbed together. Sound is inspiratory and expiratory.
71
Wheeze—sibilant
High-pitched, musical squeaking sounds that sound polyphonic. Predominant in expiration but can occur in both
72
Wheeze—sonorous rhonchi
Low-pitched; monophonic, single note, musical snoring, moaning sounds. Heard throughout the cycle, although they are more prominent on expiration.
73
Stridor
High-pitched, monophonic, inspiratory, crowing sound; louder in neck (pharynx/larnx) than over chest wall.
