Definition of AsthmaDefinition of Asthma
A chronic inflammatory disorder of the airways
Many cells and cellular elements play a role
Chronic inflammation is associated with airwayhyperresponsiveness that leads to recurrentepisodes of wheezing, breathlessness, chesttightness, and coughing
Widespread, variable, and often reversibleairflow limitation

Types of Bronchial Asthma
– Extrinsic (atopic, allergic)• Allergens: food, pollen, dust, etc.
– Intrinsic (non-atopic)• Initiated by infections, drugs,
pollutants, chemical irritants
Klasifikasi
• Asma ekstrinsik– Allergen p.u. diketahui– Test kulit positif– IgE meningkat pada 60% penderita– Onset biasanya pada anak-anak dan dewasa muda– Asma intermitten– Derajat asma bervariasi– Riwayat alergi keluarga positif

Klasifikasi
• Asma intrinsik– Allergen tidak diketahui– Test kulit negatif– IgE normal atau rendah– Onset biasanya pada orang tua– Asma terus menerus– Asma pada umumnya berat– Jarang ada riwayat alergi pada keluarga

• Allergens – 40%• Exercise (EIA)• Air pollutants• Occupational factors• Respiratory infections – viral• Chronic sinus and nose problems• Drugs and food additives – ASA, NSAIDs, ß-blockers,
ACEi, dye, sulfiting agents• Gastroesophageal reflux disease (GERD)• Psychological factors- stress
Potential Triggers of Asthma
Risk Factors for Asthma
Host factors: predispose individuals to, orprotect them from, developing asthma
Environmental factors: influence susceptibility todevelopment of asthma in predisposedindividuals, precipitate asthma exacerbations,and/or cause symptoms to persist

• History and patterns of symptoms• Measurements of lung function
– PFTs- usually WNL between a acks; ↓ FVC, FEV1
– PEFR- correlates with FEV– Measurement of airway responsiveness
• CXR• ABGs• Allergy testing (skin, IgE)

• No (or minimal)* daytime symptoms• No limitations of activity• No nocturnal symptoms• No (or minimal) need for rescue medication• Avoid adverse effects from asthma medications• Normal lung function• No exacerbation• Prevent asthma mortality
• * Minimal = twice or less per week
Therapeutic Goals of Asthma
• Suppress inflammation• Reverse inflammation• Treat bronchoconstriction• Stop exposure to risk factors that sensitized
the airway
Asthma Medications
9/22/2015
27
Antiinflammatory Agents Corticosteroids- suppress inflammatory response. Reduce
bronchial hyperresponsiveness & mucus produc on, ↑ B2receptors• Inhaled – preferred route to minimize systemic side effects
– Teaching– Monitor for oral candidiasis
• Systemic – many systemic effects – monitor blood glucose– Mast cell stabilizers- NSAID ; inhibit release of mediators
from mast cells & suppress other inflammatory cells (Intal,Tilade)
Asthma Medications
Antiinflammatory Agents Leukotriene modifiers Block action of leukotrienes Accolate, Singulair, Zyflo) Not for acute asthma attacks
Monclonal Ab to IgE ↓ circula ng IgE Prevents IgE from attaching to mast cells, thus preventing
the release of chemical mediators For asthma not controlled by corticosteroids Xolair SQ
Asthma Medications

Bronchodilators B-agonists- SA for acute bronchospasm & to
prevent exercised induced asthma (EIA) (Proventil,Alupent); LA for LT control Combination ICS + LA B-agonist (Advair) Methylxanthines- Theophylline: alternative
bronchodilator if other agents ineffective. Narrowmargin of safety & high incidence of interactionwith other medications Anticholinergics- block bronchoconstriction .
Additive effect with B-agonists (Atrovent)

Nursing Management:
1. Administer prescribed medications, such as antibiotics, cardiac
medications, bronchodilators,mucolytics, corticosteroids and
diuretics as ordered.
2. Administer oxygen to maintain Pao2 of 60 mmHg or Sao2 ˃ 90%.3. Monitor fluid balance by intake and output measurement, daily
weight.
4. Perform chest physiotherapy and suctioning to remove mucus. Teach
slow, pursed lip breathing to reduce airway obstruction.
5. If the patient becomes increasingly lethargic, can not cough or
expectorate secretions, can not cooperate with therapy, or if PH falls
below 7.30, despite use of the above therapy, report and prepare to
assist with intubation and initiation of mechanical ventilation.

Asthma Management and Prevention Program
Component 2: Identify and ReduceExposure to Risk Factors
Measures to prevent the development of asthma,and asthma exacerbations by avoiding or reducingexposure to risk factors should be implementedwherever possible.
Asthma exacerbations may be caused by a varietyof risk factors – allergens, viral infections,pollutants and drugs.
Reducing exposure to some categories of riskfactors improves the control of asthma andreduces medications needs.

A stepwise approach to pharmacologicaltherapy is recommended
The aim is to accomplish the goals oftherapy with the least possible medication
Although in many countries traditionalmethods of healing are used, their efficacyhas not yet been established and their usecan therefore not be recommended

When control as been achieved,ongoing monitoring is essential to:
- maintain control
- establish lowest step/dose treatment
Asthma control should be monitoredby the health care professional andby the patient© Global Initiative for Asthma
Treating to Maintain Asthma Control
Stepping down treatment when asthma is controlled
When controlled on medium- to high-doseinhaled glucocorticosteroids: 50% dosereduction at 3 month intervals (EvidenceB)
When controlled on low-dose inhaledglucocorticosteroids: switch to once-dailydosing (Evidence A)

Treating to Maintain Asthma Control
Stepping down treatment when asthma is controlled When controlled on combination inhaled
glucocorticosteroids and long-actinginhaled β2-agonist, reduce dose of inhaledglucocorticosteroid by 50% whilecontinuing the long-acting β2-agonist(Evidence B)
If control is maintained, reduce to low-dose inhaled glucocorticosteroids andstop long-acting β2-agonist (Evidence D)© Global Initiative for Asthma
Treating to Maintain Asthma Control
Stepping up treatment in response to loss of control
Rapid-onset, short-acting or long-acting inhaled β2-agonistbronchodilators provide temporaryrelief.

Stepping up treatment in response to loss of control Use of a combination rapid and long-acting
inhaled β2-agonist (e.g., formoterol) and aninhaled glucocorticosteroid (e.g., budesonide)in a single inhaler both as a controller andreliever is effecting in maintaining a high levelof asthma control and reduces exacerbations(Evidence A)
Doubling the dose of inhaled glucocortico-steroids is not effective, and is notrecommended (Evidence A)© Global Initiative for Asthma
Exacerbations of asthma are episodes ofprogressive increase in shortness of breath,cough, wheezing, or chest tightness
Exacerbations are characterized by decreasesin expiratory airflow that can be quantified andmonitored by measurement of lung function(FEV1 or PEF)
Severe exacerbations are potentially life-threatening and treatment requires closesupervision

Although there is no cure for asthma,appropriate management that includes apartnership between the physician and thepatient/family most often results in theachievement of control
