Acute bronchitis:
When to call MD
A
fever comes back, hemoptysis, difficulty breathing
25
if acute bronchitis doesn’t resolve, it becomes
CHRONIC BROCHITIS
26
Parenchyma:
any form of the lung tissue: bronchioles, bronchi, blood vessels, interstitium, and alveoli
27
Inflammation reaction produces exudate and WBC that fills the normally air- filled spaces of alveoli & bronchiole
Pneumonia
28
Inflammation of Lung Parenchyma
Pneumonia
29
If edema and excess secretions of alveoli:
gas exchange affected
30
Lobar pneumonia:
large portion of 1 or more lobes involved
31
Bronchopneumonia:
patchy areas within the lung (more common)
32
With pneumonia, there is fear that the infection will go into
The bloodstream
33
3 Types of pneumonia:
Bacterial :staphylococcal, legionella
Viral: COVID, RSV
Aspiration: chemical or food
34
Streptococcal pneumonia
sudden onset -Chills, rapidly rising fever, pleuritic chest pain aggravated by deep breathing
Pt looks ill, RR 25-45
35
RSV not at bad as
bacterial
36
Orthopnea –
SOB when laying down
37
A peculiar broken quality of the voice sounds, like the bleating of a goat, heard about the upper level of the fluid in cases of pleurisy with effusion
egophony
38
Low BP, HR, may see peripheral cyanosis
with
pneumonia
39
Four ways of acquiring pneumonia
Community acquired
Healthcare acquired
Hospital acquired
Ventilator acquired
40
also known as walking pneumonia
community acquired pneumonia
41
Bacteria that causes pneumonia
Strep, mycoplasma, Haemophilus influenza, c. pneumonia, legionella, RSV
42
S. Aureus causes
sepsis
43
Diagnosing pneumonia
History, physical examination, chest xray
Auscultation of lungs: rhonchi
Sputum and blood cultures
44
When antibiotics are not working (for pneumonia), this is performed
brochoscopy
45
Obtaining sputum for C&S
Best if done in the morning
No mouthwash, food, or drink before
May brush teeth
46
Patients too weak to cough ->
suction
47
This device can help to trend hemoglobin
pulse oximeter
48
This is done to mobilize secretions
Chest PT
49
Pneumonia management:
Promote Fluid Intake to 2-3 liters /day unless it is
A cardiac patient
50
Pneumonia management:
Observe for s/s of
hypoxemia…restlessness, cyanosis (late)
51
Huffing and puffing can cause
fatigue
52
Infectious disease the affects the lung parenchyma. May travel via lymph and blood to other parts of body
Tuberculosis
53
Airborne transmission via talking, coughing, sneezing, laughing or singing.
Tuberculosis
54
Patho of tuberculosis
Bacteria is deposited in alveoli and begin to multiply – immune response is initiated
55
10% of latent tuberculosis will become
active
56
Bacteria can remain dormant in _____% of people: LATENT
90% of people
57
TB CLINICAL MANIFESTATIONS
Low grade fever, night sweats, fatigue, weight loss
Cough – nonproductive, mucopurulent or hemoptysis
Lungs sounds: diminished, crackles, fremitus, egophony
58
TB DIAGNOSIS
Chest XRAY: lesions
Sputum culture : AFB (but not all AFB is M. tuberculosis)
Mantoux test
Blood tests: QuantiFERON-TB Gold & T-SPOT
59
mantoux test reading
Measure the area of induration, not redness
60
Positive TB test could mean
active or latent
61
Anti-TB agents are taken for
6-12 months
62
Increasing drug resistance to TB – need to use
4 or more meds
63
Latent TB – consider
treating
64
How to take TB meds
Take med on empty stomach or at least 1 hr before meals
65
using force of gravity to promote removal of bronchial secretions
Postural drainage
66
rare type of TB, spread via blood to other parts of body
Miliary tb
67
Air gets trapped in the lungs, hard to get out
Air Trapping
68
Primary cause of COPD
Smoking primary cause- cilia destroyed, secretions retained, alveolar walls destroyed
69
Genetic COPD:
Problem with the alveoli, usually starts at age 20. alpha1-antitrypsin deficiency- effects alveoli (younger patients)
70
Elderly patients with COPD–
elastic recoil decreases, they can not expectorate
71
Abnormal distention of the airspaces & destruction of alveoli walls. Alveoli overinflate, collapse upon expiration
EMPHSEMA
72
Resistance to pulmonary blood flow causes increase BP in pulmonary artery
Leads to right sided heart failure (edema due to backup)
EMPHSEMA
73
Respiratory acidosis as carbon dioxide elimination impaired
EMPHSEMA
74
Presence of cough and sputum production for at least 3 months in each of 2 consecutive years.
Irritant such as smoke, causes inflammatory response and hypersecretion of mucus
Creates narrowed spaces in bronchus
Increased mucus & plugging, impairing ciliary function
Bronchial walls thicken, adjacent alveoli become damaged and fibrosed.
CHRONIC BRONCHITIS (COPD)
75
Diagnosing COPD
ABG (High O2)
Pulmonary function test - (decreased)
Chest x-ray (late disease, dilated airways)
76
Weight loss in COPD patient because
dyspnea interferes with eating and work of breathing uses calories
77
COPD patients have a higher risk for
lung cancer
78
Cardinal Symptoms of COPD exacerbation:
Increased dyspnea, increase in sputum, and sputum purulence
79
Barrel chest: usually with
emphysema
80
Too much oxygen –
can decrease respiratory drive worsening hypercapnia
81
Too much CO2 in blood
hypercapnia
82
ABG if patient is
de-saturating , altered mental status
83
Oxygen level (nasal cannula) for COPD
1-2L
84
Bipap and Cpap blows off extra
CO2
85
High flow nasal cannula supplied
warmed humidified air up to 60L, usually given at low FiO2
86
High Flow nasal cannula can be used at a low FIO2, it rids CO2 from .
deadspace because of force it is blown in
87
Most common chronic disease of childhood
Asthma
88
Allergy is number one factor in
Asthma
89
Asthma triggers:
Airway irritants such as cold, heat, weather changes, smoke, strong odors, hormones, stress, exercise, URI’s, GERD
90
Carpeting and heavy drapes can
collect dust and dander
91
Med given to reduce inflammatory response in asthma
singulair
92
In asthma, there is very fast constriction, the lumen gets
small causing wheezing
93
Asthma:
Patient will not lay down because of
fear of drowning
94
At home Peak Flow rate Meter, colors and meanings
Green zone – normal
Yellow zone – use Rescue Inhaler
Red zone – get to some help ASAP
95
Labs for asthma:
ABG’s, IgE
96
IgE
Immunoglobin E (allergy response)
97
Magnesium IV counteracts
calcium
98
Mucus plugging from bronchospasm can lead to
asphyxia if not treated
99
