what is COPD
preventable, treatable, slowly progressive respiratory disease characterized by airflow limitations that are not fully reversible
-may include chronic obstructive bronchitis and emphysema
step 1 of COPD development
exposure to irritating inhaled substance (smoking, workplace, resp infection)
-changes cellular makeup
step 2 of COPD development
the inflammatory response in airways and lungs
step 3 of COPD development
increased mucus production and narrowing of bronchioles, chronic hypoxia
-inc WBC and dec air exchange
step 4 of COPD development
hyperinflation of the alveoli
inspiration more difficult to reduce gas exchange
-diaphragm wont be able to fully contract
COPD risk factors
-smoking
-indoor or outdoor pollution
-occupational exposure
-second hand smoke
-genetics (alpha-1 antitrypsin deficiency (AAT))
-COPD develops over time, dx usally 40+
diagnosis criteria for chronic bronchitis
presence of a cough and sputum production for at least 3 months in each of 2 consecutive years
what is chronic bronchitis
inflammation of the bronchi
-vasodilaion, congestion, edema of mucosa
-bronchospasm
-inc mucus production and mucus plugging
-thickening of bronchial walls
-alveoli become damaged/fibrosed
what is emphysema
impaired gas exchange resulting from destruction of the walls of overdistended alveoli
-permanent overdistension of air spaces
-air passages are obstructed
-increased ventilatory “dead space”
-less function of lung tissue & inc work of breathing
clinical manifestations of COPD
-a progressive disease characterized by 1.chronic cough 2.sputum production 3.dyspnea
-weight loss
-use of accessory muscles (barrel chest)
-poor sleep, dec ADL’s
how may a patient present with empysema
in tripod pose + use of accessory muscles
-may exhale w pursed lips
how is COPD diagnosed
-health hx and physical assessment
-pulmonary function test
-spirometry
-ABGs
-chest xray
-ATT screening
-vitals w o2 sats
-skin assess
-phx,fhx, s&s
medication to improve COPD
surgical management of COPD
bullectomy (remove air pockets in lungs before they pop)
lung transplant (not usually for COPD)
lung volume reduction (remove dead lung/space)
-pulmonary rehabilitation
nutrition for people with COPD
increased protein, calories, and carb diet d/t energy loss
offer boost
nursing care for COPD
-manage exacerbations (meds)
-airway maintenance
-monitor for complications (o2 sats)
-improving activity tolerance
-drug therapy
-o2 therapy
-patient teaching
complications for COPD
-respiratory infections
-hypoxemia & acidosis
-cor pulmonale
-heart failure
-pulmonary hypertension
-acute respiratory failure
-anxiety and depression
