Chronic Airflow Limitation (CAL)
Term used for Chronic lung diseases:
- Emphysema
- Chronic Bronchitis
- Bronchial Asthma
COPD
Chronic Obstructive Pulmonary Disease
 Emphysema
 Chronic Bronchitis
Bronchospasm, dyspnea
Non-reversible and progressive
Continously symptomatic
Asthma
Reversible airflow obstruction d/t:
Inflammation
Airway hyperresponsiveness
Hyperresponsiveness leading to
bronchospasms
Asthma
- stimulus or allergen- chemical mediators
released. Within minutes:
Dyspnea
Wheezing
Cough
Mucus production
Inflammatory process
TRIGGER
Allergen binds to IgE
Release of inflammatory
chemicals
WBCs come to
the area
WBCs release Mediators which
produce more inflammation
Blood vessel dilation/ Capillary leak
Tissue swelling / Increased secretion
Asthma
 Common agents or stimuli:
-fog, smog, smoke
-odors, aerosols
-exercise
-cold air
 Allergens- dust mites, animal dander, pollen,
cockroaches, foods, medicines.
Asthma
 FOCUSED Respiratory assessment
1. Expiratory and Inspiratory wheezing
2. Dry or moist cough
3. Dyspnea, signs of hypoxemia, anxiety
4. increased HR, BP, RR
5. Diaphoresis, Pallor
6. Cyanosis
7. Nasal flaring
8. Use of accessory muscles
Asthma
 Diagnostic Assessment
 ABGs / PO2 low, PCO2 high, PH low
 SaO2 low
 Eosinophils / serum and sputum
 PFTs / FEV and PERF
 CXR
Asthma
STEP SYSTEM
MILD INTERMITTENT
MILD PERSISTENT
MODERATE PERSISTENT
SEVERE PERSISTENT
Complications of Asthma
- Respiratory infections
- Status Asthmaticus
- pneumothorax
- respiratory arrest
- cardiac arrest
Asthma
Nursing Diagnoses
1. Impaired Gas Exchange related to
alveolar
membrane changes, airflow
limitation, respiratory muscle fatigue,
excess production of mucus.
2. Ineffective Breathing pattern related to
airflow obstruction (narrowed airways),
and fatigue.
3. Ineffective Airway Clearance related to
excessive secretions, fatigue and
ineffective cough.
Asthma Interventions
 Client Education
A. Identify causes
B. Proper environmental changes
C. Stress management, rest, and sleep
D. Correct use of inhalers
E. Correct use of peak flow meter and step wise
approach to med management
F. What to do if an attack occurs
Asthma
– How to use a METERED DOSE inhaler
(without spacer) correctly:
1. Shake inhaler
2. Tilt head back, breathe out fully
3. Open mouth, mouthpiece 1-2” away
4. As you begin to breathe in deeply, press down
and release medicine.
5. Breathe in deeply and slowly for 3-5 sec.
6. Hold your breathe for 10 sec
7. Breathe out slowly
Asthma
Drug Therapy
 Bronchodilator
 Anti-inflammatory
 Beta agonists
short-acting
long-acting
 Anti-cholinergics
 Methylxanthines





Corticosteroids
Anti-leukotriene
Mast cell stabilizers
Monoclonal antibodies
Inhaled agents
Asthma
 Pharmacologic stepped approach to treating
asthma symptoms
 Step 1- mild intermittent- beta 2 agonist
 Step 2.- mild persistent – add cromolyn
 Step 3.- moderate persistent- add inhaled
corticosteroid , may add theophylline.
 Step 4.- Severe persistent- add po steroids
Chronic Obstructive Pulmonary Disease
EMPHYSEMA







Loss of lung elasticity
Hyperinflation of lungs / air trapping
Diaphragm flattening
Increased airflow resistance
Ineffective gas exchange
Retained CO2 (hypercapnia)
Chronic respiratory acidosis
Chronic Obstructive Pulmonary Disease
CHRONIC BRONCHITIS






Chronic inflammation of airways
Mucosol edema
Increased # of mucous glands
Bronchial wall thickening
Impaired airflow AND gas exchange
Hypoxemia, hypercapnia, respiratory acidosis
COPD
 FOCUSED assessment
1. Rapid, shallow respirations & dyspnea
2. Irregular breathing patterns
3. Moist cough
4. Limited diaphragmatic excursion
5. Decreased fremitus
6. Hyperresonant percussion
7. Crackles
8. Barrel chest
9. Cyanosis
10.Clubbing
11.Orthopneic posturing
COPD
 DIAGNOSTIC ASSESSMENT

ECG
H&H, Electrolytes, WBC
Complications of COPD

Pneumonia
 Community acquired pneumonia (CAP)
Versus
 Nosocomial pneumonia
 Higher incidence in:
Elderly, immunocompromised, CAL,
mechanically vented, chronically ill
 5th leading cause of death in US
