25
Risk Factors for Emphysema
genetic mutations in α1 anti-trypsin, smoking, exposure to 2nd hand smoke or air pollution
26
What happen with emphysema
Activation of destructive enzymes breakdown alveolar walls, floppy airway (increased compliance), air trapping and decreased surface area for gas exchange
27
What is the biggest cause of emphysema?
smoking
28
chronic bronchitis
- Risk factors: same as bronchitis - Chronic exposure to tobacco smoke or air pollution leads to diminished mucocilliary escalator fx, hypertrophy of goblet cells & bronchiolar smooth muscle and chronic infection --> chronic infection leads to chronic airway inflammation (air trapping secondary to secretion retention)
29
Asthma risk factors
allergies, exposure to smoke or smoking, frequent viral or bacterial respiratory infections, stress, exposure to cold air, GERD or exposure to air pollutants
30
what happens in asthma?
- Irritants lead to reversible inflammatory response in bronchioles - Irritant can by inhaled, ingested or in contact with skin - Respiratory infection likely also contributes as well as air temperature – Bronchial smooth muscle constricts leading to air trapping & alveolar hyperinflation. – Increased mucous production and bronchiolar mucosal inflammation and thickening also occur, leading to fluid infiltration
31
Pneumonia Risk Factors
aphasia, immobilization, malnutrition, COPD, heart disease, AIDS, other chronic diseases, asplenic patients, exposure to infected patients
32
Pneumonia
Inflammatory reaction of the distal airway to insult/microorganism Occurs in stages
33
Community acquired pneumonia
develops infection prior to hospitalization
34
Nosocomial pneumonia
- develops infection within 48 hours of hospitalization
35
Infectious agents related to pneumonia
``` streptococcus pneumonia (pneumococcus) is the most common cause and prototype. Also: Haemophilus influenza, Staph infections (MRSA), Mycoplasma pneumonia (atypical) and many others ```
36
ARDS Risk Factors
severe, systemic or pulmonary insult resulting in strong inflammatory or immune response
37
things that can cause ARDS
pancreatitis, pneumonia, acute renal failure, shock, etc
38
ARDS can lead to:
* Pulmonary edema * Thickening of inter-alveolar-capillary space * Acute hypoxia * Stiff lung (reduced compliance) * Increased work of breathing * Fibrosis
39
what exactly is ARDS?
intense inflammatory reaction in distal airway
40
what is ARDS all about?
- cytokines | - increased lung stiffness (decreased compliance) and increased work of breathing
41
Lung cancer risk factors
smoking, genetic mutations linked to cancer or neoplastic conditions, exposure to air pollution, second hand smoke or carcinogens
42
what do 98% of lung cancers arise from?
bronchial epithelium
43
what does lung cancer typically start as?
"coin lesion" along bronchi with mix of cartilage and epithelial cells
44
widespread perneoplastic effects from lung cancer
carcinoid syndrome (skin flushing, diarrhea, dyspnea, asthma- like symptoms), cushing syndrome, hyper/hypocalcemia, weight loss, cachexia
45
pulmonary embolism risk factors
immobilization, thrombophlebitis, other conditions affecting lower extremity movement (SCI, bone fractures, etc...), hospitalization & coagulation disorders
46
what is a pulmonary embolism
Sudden, life-threatening occlusion of a pulmonary artery by embolism or thrombus --> Leads to ventilation-perfusion mismatching
47
where are most PEs from?
LE | life threatening ones from above the knee
48
Congestive Heart Failure Risk Factors
Deconditioning, HTN, smoking, diabetes, atherosclerosis, obesity, hyperlipidemia, MI, valvular heart disease, viral or bacterial infections, hyper/hypothyroidism
49
complex pathophysiology of congestive heart failure
Typically takes years to develop (5-30 years), but can occur acutely w/ infection --> Heart can’t meet demands of body: – Heart & vasculature undergoes remodeling. – Blood “backs up” into pulmonary or systemic system or both. – Results in edema, SOB, fatigue, exercise intolerance, etc
50
Pneumothorax Risk Factors
Contusion/trauma, COPD, connective tissue disorders, TB, tall stature (2° to elevated intra-thoracic pressure)
51
What is pneumothorax?
Air enters pleural space, leading to collapse of lung secondary to penetrating wound into pleural cavity or breech in pleural membrane resulting in rapid collapse of the lung, down to residual volume • Ventilation: perfusion mismatching. • Life-threatening condition
52
Pleural Effusion risk factors?
pneumonia, connective tissue disorder, CHF, lymphedema, neoplasm, TB, pancreatitis
53
What is Pleural Effusion?
Transudative or exudative fluid in pleural space resulting from an inflammatory condition or infection (pneumonia), other dx process. • May have insidious onset and mimic musculoskeletal pain except pain related to breathing cycle
54
What is pulmonary fibrosis?
Describes “interstitial lung disease”: conditions where functional lung parenchymal tissue is replaced by scar tissue • Lung is thickened, stiff, and scarred
55
What does pulmonary fibrosis typically arise from?
inflammatory process that is triggered by: • Pneumonia • Exposure to irritants (smoke, dust, silicon, etc...) • Autoimmune disease
56
What does pulmonary fibrosis result in?
increased lung stiffness, decreased diffusion capacity and SOB, especially with Ex
57
Emphysema history and physical exam
long hx of smoking or second hand smoke. Look for family hx in non-smokers. – Wheezing, hyper-inflated lung/barrel chest, flat diaphragm, hypertrophy of accessory mm, pink complexion, cachexia, hypercapnia and hypoxemia. – Heart failure later in disease process – May or may not have productive cough
58
Chronic Bronchitis History and Exam
smoking or exposure to pollution – Wheezing, hyper-inflated lung/barrel chest, flat diaphragm, reliance on accessory mm, bluish/cyanotic complexion, hypercapnia and hypoxemia. – Heart failure develops 10-20 years after respiratory sx. – Productive cough (worse in AM) with bad breath
59
Asthma History and Exam
hx of recurrent respiratory infections, runny nose or swollen nasal passages, allergic skin conditions (such as eczema), allergies, smoking or exposure to smoke or pollution, associated with anxiety disorders and other psychological factors --> Exacerbated by viral and other respiratory tract infections. – Occurs acutely with wheezing, anxiety during attack, use of accessory mm, reversible with bronchodilators
60
Pneumonia History and Exam
Typically occurs acutely, but “walking pneumonia” may be insidious. Common in patients with prolonged bed rest, immune-suppressed patients, elderly, very young, exposure to pt with TB or other respiratory infectious agent, aspiration. – High fever, crackles or wheezing or diminished breath sounds, productive couch, hemoptysis and chest pain
61
good tests for pneumonia
Egophony, bronchophony, whispered pectoriloquy or percussion testing suggest consolidation over involved lung
62

COVID
• Produces a special version of ARDS that is similar in most ways to other types except: – Mismatch between severity of hypoxemia and calculated stiffness – Stiffness or elastance is lower in “most” cases of Covid-19! – Covid-19-ARDS is referred to a “L-type ARDS” – Some patients report less SOB, but still very hypoxic – Patients still benefit from ventilation w/ PEEP, prone positioning, supplemental O2, et
