x Resp: COPD (Ms. Ci) Flashcards
COPD is 3rd leading cause of death in US
COPD is 3rd leading cause of death in US
COPD (Chronic Obstructive Pulmonary Disorder)
-group of pulmonary disorders
-progressive, inflammatory disease
-irreversible airflow limitations
NO CURE, CAN NOT REVERSE Lung Damage
COPD: several disease..
- Chronic Bronchitis
- Emphysema
- Chronic Asthma
- Bronchiectasis
COPD Def
permanent blockage of the pulmonary system and interfere w gas exchange (i.e. one bronchi or alveoli become completely obstructed)
Lung
Trachea
Bronchi
Bronchioles
Alveoli`
COPD several disorders
Chronic Bronchitis - affects bronchi
Emphysema - affect alveoli
Less air flow d/t:
- Bronchi / Bronchioles, loose elastic quality
- walls btw alveoli destroyed
- airway walls thick and inflamed
- excess mucus obstructs airways
COPD: Causes
- Smoking
- exp to pollution, fumes, dust
- Gx, alpha1 antitrypsin deficiency (protein protects lung tissue fro enzymes of inflammatory cells. LO levels lead to lung damage/COPD if exposed to pollution, fumes, dust)
EMPHYSEMA
- Alveolar disease
- abnormal perm enlarge of alveoli will destroy alveolar walls.
- many small alveolar provide maximum surface area.
Emphysema: Pathos
- Bronchiole lumen narros —> traps air during expiration
- trapped air –> alveolar distention and hyperinflate
- hyperinflation –> several alveoli rupture and make 1 large alveoli
- larger less elastic sacs CAN NOT completely force air our
- less alveolar = less surface area
- must breath harder
- Expiration becomes ACTIVE process. burn more calories. (thats why they are thin)
Inspiration - Active
Expiration - Passive
Emphysema:SS
aka Pink Puffer
- Polycythemia (Skin tone Pink d/t hypoxia. body UP RBCs to UP O2 carrying capacity
- Barrel chest (d/t inflated alveolar)
- Dyspnea
- UP resting resp rate
- initially little sputum ==>copious sputum
- Clubbing (d/t chronic hypoxia)
- LO breath sounds
- rales
- thin appearance
- retain CO2 (respiratory acidosis)
- pursed lip breathing
- frequent URI
- use of accessory muscles
- Cor Pulmonae (Rt sided heart failure)
Emphysema: Dx Tests
- Med Hx (smoker, WTC worker)
- PFTs
- ABG
- Blood test: alpa1-antitrypsin, cbc
Emphysema: MM
- Broncho dilators
- Chest PT (loosen mucus, i.e. cupping)
- O2 1-2L/min
- Abx
- Diuretics
- Anti Inflam Agents/Steroids
- Pul Rehab
Emphysema: NI
-semi/hi fowlers
-O2 1-2L/min
-pt education
-Diet: UP protein, calorie
Fluid: encourage 2-3L/day to loosen secretions, unless contraindicated..renal, heart probs)
-STOP SMOKING
-Avoid respiratory Depp?
-Vaccine )flu/pna)
-pursed lip breathing
CHRONIC BRONCHITIS
- presence of a productive cough for at least 3 mos - year over 2 consecutive years
- inflam of bronchi which lead to UP mucous
Chronic Bronchitis: Pathos
- bronchi inflam –> DEC in bronchi diameter
- less air flowing thru
- bronchi inflam –> UP mucous production –> airway obstruction
Chronic Bronchitis: Causes
- smoking/2nd hand smoke
- repeated acute bronchitis attacks
- Envt pollution
Chronic Bronchitis: Dx Tests
- PFTs
- ABG
- CxR
- CBC
Chronic Bronchitis: SS
- productive cough
- LO breath sounds, wheezes, raunchy
- Cyanosis, “Blue Bloaters”
- Hypoxia
- Acidosis
- edematous
- UP resp rate
- Dyspnea
- Cor Pulmonea
- heart enlargement
- use accessory muscles to breath
Chronic Bronchitis: MM
- Bronchodilators (open airway)
- Steroids (LO inflam)
- Mucolytics (loosen mucous)
Chronic Bronchitis: NIs
- MEd education (steroids, taper off)
- PO fluids
- suctioning
- monitor change in sputum
- STOP SMOKING
- nutrition assessed
ASTHMA
chronic inflame disease of airways characterized by airway hyper responsiveness to variety of stimuli
- resolves spontaneously or w meds
- reversible
Asthma: Types
- Extrinisic
- Intrinsic
