25
Lobes are separated by ___ that run ___
Fissures that run obliquely
26

Forms an envelope between the lungs and the chest
28
Pleural cavit contains
A few milliliters of lubricating fluid
29
The cavity normally has a
Vacuum that holds the lungs tightly against the chest
30
The lubricating fluid prevents
Friction
31
The trachea lies anterior to the
Esophagus
32
Right bronchus versus the left bronchus
Right- shorter, wider, more vertical than left
33
Bronchial tree
Protects the alveoli from small particulate matter using mucus and cilia
34
Four major functions of respiratory system
-supplies oxygen -removes carbon dioxide -maintains homeostasis -maintain heat exchange
35
The respiratory system develops in utero but does not function until
Brith
36
During pregnancy the growing uterus elevates the diaphragm by
4 cam
37
Suprasternal notch
Hollow u shaped depression just above the sternum, imbetween the clavicles
38
Sternum
Contains three parts: manubrium, body, xiphoid -contains the manubriosternal angle
39
Manubriosternal angle
Part of the manubrium of the sternum -walk fingers down until you feel a distinct bony ridge
40
Sternal angle
Angle of Louis -continuous with the second rib -helpful to start counting ribs
41
The angle of Louis also marks the
Tracheal bifurcation into the right/left main bronchi
42
Costal angle
Right/left costal margins from an angle where they meet at the xiphoid process -90 degrees or less
43
Vertebra prominens
Start at the base of your neck, flex your head and feel fo rate most prominent bony protrusion there -this is C7 -if there are two bony prominens, the upper one is C7, lower is T1
44
Spinous processes
Spinous process align with their same numbered ribs only down to T4 -after T4 angle downward from their vertebral bodies
45
Inferior border of the scapula
These are located symmetrically in each hemithorax -lower tip is usually at the level of the seventh or eight rib
46
Twelfth rib
Palpate midway between the spine and patients side to identify the free tip of the twelfth rib
47
Chest reference lines
Midsternal line (imbetween both clavicles), midclavicular line (center of each clavicle), anterior axillary line (end of clavicle)
48
Reference lines of the posterior chest wall
Vertebral line (down the spine), scapular line (extends through inferior angle of scapula when arms are at the side)
49
Reference lines of the lateral chest
-anterior axillary line (extends down form anterior axillary fold) -posterior axillary line (down from posterior axillary fold) -midaxillary line (down from apex of axilla, parallel to other two)
50
Acinus
Functional respiratory unit that consist of the bronchioles, alveolar ducts, alveolar sacs and alveoli
51
Hypercapnia vs hypoxemia
Hypercapnia- increase of carbon dioxide in the blood (the normal stimulus to breathe) Hypoxemia- decrease of oxygen in the blood (also increases respirations but is less effective)
52
Surfactant
Complex liquid substance needed for sustained inflation of air sacs -at 32 weeks there is a sufficient amount
53
When does the respiratory system begin function
At birth
54
Prenatal exposure to cigarettes can cause
-chronic hypoxia -low birth weight -sensitized fetal brain to nicotine (inc risk of addition at a later age)
55
Postnatal exposure to tobacco smoke
-otitis media -sudden infant death syndrome -lower respiratory tract infections -asthma
56
An enlarging uterus elevates the diaphragm how many cm?
4 cm
57
Physiologic dyspnea
An increased awareness of the need to breathe -pregnancy -not associated with cough, wheezing or exercise
58
What reduces the mobility of the thorax?
The costal cartilage becomes calcified and decrease in elastic properties within the lungs (more rigid)
59
In older adults there is a increase in small airway closure, and this causes
-Decreased vital capacity (maximum amount of air exhaled after maximum filling) -increased residual volume (amount of air remaining in lungs after forceful expiration)
60
Hemoptysis
Coughing up blood
61
Orthopnea
Shortness of breath associated with a position -supine piston
62
Paroxysmal nocturnal dyspnea
Awakening in the night unable to breathe, and Alicia ting this by changing position (sitting upright)
63
Important to note the ___ the patient takes the breathe
Position
64
Assessing ___ color and condition may assist with amount of oxygen patient is receiving
Skin
65
Symmetrical expansion
Placing hands on the posterolateral chest wall, with your thumbs at level of T9/10 -as patient breathes hands should move symmetrically
66
Shortness of breath symptoms in babies
Headbobbing, suprasternal, intercostal contractions, abdominal breathing, subcostal
67
Shortness of breath symptoms
1-2 word answers, panting, tripod position, I CANT BREATHE
68
Initial assessment (acute)
Loss of consciousness, skin color (cyanosis = hypoxemia), rhythm, RR,
69
Intital assessment (chronic)
Clubbing, chest wall changes
70
Palpation
-symmetry (size, shape, expansion) -lesions, lumps, masses -subcutaneous emphysema -tactile fremitus
71
Subcutaneous emphysema
Air trapped under skin, bubbly feeling -leak in the system (injury, surgery, chest tube)
72
Tactile fremitus
Palpable Vibration of chest wall -sound thru lung tissue
73
Lung consolidation
Increases risk of fremitus -air in healthy lung replaced with something else -increased density
74
Hyper resonance in lungs
More air than should be
75
Dull sound in lungs
Fluid in lungs, consolidation
76
Bronchiovesicular
Even intake and output -found around sternum, and upper spinal processes on back
77
Bronchial
Shorter intake, longer outtake -anterior neck region around trachea
78
Vesicular
Long intake, short outtake -around lung area p/a
79
Adventitculous sounds
-crackles (fine, coarse) -wheezes -rhonchi
80
When are crackles normal?
After laying down/napping -alvolectic crackles (alveoli popping back open) ***disapears after a couple breaths
81
Asthma is heard
In both lungs q
82
Pregnant women
Costal angle increases, rib injury —>
83
Resonance
Low pitched, clear hollow sound -healthy lung tissue
84
Chest physiotherapy
Encourages breakup and movement of lung secretions -for sticky secretions -cystic fibrosis
85
Kyphosis
Outward curvature of the thoracic spine
86
Pectins excavatum vs carinatum
Excavatum - sunken sternum Carinatum- forward protrusion
87
Decreased tactile fremitus
Any obstructs transmission of vibrations
88
Increased tactile fremitus
Increased density of lung tissue -better conduction for vibrations
89
Pleural friction fremitus
Inflammation of parietalor visceral pleura -coarse grating sound when rubbing together
90
Atelectasis
Collapsed or shrunken section of the alveoli as a result of airway obstruction
91
Lobar pneumonia
Infection of the lung parenchyma leaves alveolar membrane edema and porous, full of fluid, bacteria, RBC and WBC
92
Emphysema
Destruction of pulmonary connective tissue -enlargement of air sacs
93
Pleural effusion
Collection of excess fluid in trapleural space
94
Pneumothorax
Partial or complete lung collapse due to free air in the pleural space
95

Acute pulmonary insult damages alveolar capillary membrane
96
Acute respiratory distress syndrome
