Asthma is a chronic respiratory condition characterized by airway constriction, inflammation, and mucus production, leading to breathing difficulties. Asthma attacks can range from mild to life-threatening, underscoring the importance of effective management and a well-structured plan of care. While there is no definitive cure, asthma can be effectively controlled with proper treatment and management strategies, significantly improving the quality of life for those affected.
Asthma is particularly prevalent in children, making it the most common chronic childhood disease. Children’s airways, being smaller, are more susceptible to the effects of inflammation and mucus buildup, making them highly sensitive to asthma triggers. Although approximately half of children may see their asthma symptoms diminish by adolescence, the condition can recur in adulthood.
This article will delve into the nursing process for asthma care, focusing on developing a comprehensive plan of care based on nursing diagnoses. This guide is intended to enhance understanding of asthma management for nurses and healthcare professionals, ultimately leading to improved patient outcomes.
The Nursing Process in Asthma Care
Nurses are at the forefront of asthma management, frequently interacting with patients in various stages of the condition – from acute exacerbations requiring immediate intervention to chronic management within a patient’s health history. A nurse’s role is pivotal in patient education, covering symptoms, triggers, medication management, and coping strategies, all essential components of an effective asthma care plan.
Comprehensive Nursing Assessment for Asthma
The cornerstone of asthma nursing care is a thorough nursing assessment. This involves gathering comprehensive data encompassing physical, psychosocial, emotional, and diagnostic aspects of the patient’s condition. This section will outline the subjective and objective data collection crucial for formulating an accurate nursing diagnosis and subsequent plan of care for asthma.
Detailed Review of Health History
1. Identify General Asthma Symptoms: Recognizing common asthma symptoms is the first step in assessment. These include:
- Persistent coughing, which may worsen at night or early morning
- Wheezing, an audible whistling sound during breathing, especially exhalation
- Shortness of breath (dyspnea), a sensation of breathlessness or difficulty breathing
- Chest tightness, a constricting or heavy feeling in the chest
2. Pinpoint Asthma Triggers: Understanding triggers is crucial for preventative management. Asthma symptoms can be exacerbated by various factors, including:
- Weather changes, particularly cold or drastic shifts

Physical Examination
1. Vital Signs Monitoring: Vital signs provide immediate clues to the severity of an asthma exacerbation:
Mild Exacerbation:
- Elevated respiratory rate
- Heart rate below 100 bpm
- Absence of pulsus paradoxus (a drop in systolic blood pressure during inspiration)
- SpO2 (peripheral oxygen saturation) greater than 95%
Moderate Exacerbation:
- Increased respiratory rate
- Heart rate between 100-120 bpm
- Pulsus paradoxus may be present
- SpO2 between 91-95%
Severe Exacerbation:
- Respiratory rate exceeding 30 breaths per minute
- Heart rate greater than 120 bpm
- SpO2 less than 90%
2. Physical Assessment Findings: Clinical observations are crucial in determining exacerbation severity:
Mild Exacerbation:
- Breathlessness occurs after physical activity
- Patient can speak in full sentences and lie down comfortably
Moderate Exacerbation:
- Breathlessness while talking
- Use of accessory muscles to breathe
- Retractions, nasal flaring, and abdominal breathing in children
- Poor feeding in infants, weaker cry
Severe Exacerbation:
- Breathlessness at rest
- Tripod positioning (leaning forward with hands on knees for support)
- Accessory muscle use and chest retractions
- Agitation or confusion
- Ability to speak only in single words
3. Signs of Respiratory Failure: Recognizing impending respiratory failure is critical:
- In respiratory arrest, children may exhibit drowsiness and confusion.
- Wheezing may be absent in severe airway constriction (“silent chest”).
- Severe hypoxemia accompanied by bradycardia.
- Diaphoresis (sweating), bradypnea (slow breathing), confusion, and agitation.
- Patient may become distressed and pull at oxygen devices, reporting an inability to breathe as respiratory fatigue worsens.
4. Lung Auscultation: Listening to lung sounds is a key diagnostic step:
- Auscultation typically reveals bilateral, expiratory wheezing.
- In severe exacerbations, wheezing may be present during both inspiration and expiration.
- In life-threatening asthma, absent lung sounds may be noted due to minimal air movement.
5. Cough Pattern Observation: Cough characteristics can provide insights, especially in nocturnal asthma, where coughing often occurs at night or in the early morning due to increased bronchoconstriction.
6. Exercise-Induced Symptoms: Monitor for symptoms triggered by exercise, which can include typical asthma symptoms along with sore throat or gastrointestinal upset.
Diagnostic Procedures
1. Peak Flow Meter Use: Peak flow meters are portable devices used to measure peak expiratory flow rate (PEFR), reflecting airflow obstruction. They help:
- Assess asthma severity compared to a patient’s baseline.
- Monitor response to treatment.
- Guide self-management at home.
- Measurements are expressed as a percentage of predicted peak flow, correlating with asthma attack severity.
2. Arterial Blood Gases (ABGs): ABG tests measure blood oxygen and carbon dioxide levels and pH balance. In asthma, ABGs can detect:
- Respiratory alkalosis (early stages due to hyperventilation).
- Hypoxemia (low blood oxygen levels).
- In severe cases, respiratory acidosis (due to carbon dioxide retention and respiratory fatigue).
3. Electrocardiogram (ECG): ECG is recommended for patients with severe asthma symptoms to assess cardiac function and rule out cardiac issues mimicking asthma.
4. Chest X-ray: Chest X-rays are valuable for:
- Ruling out other pulmonary diseases that may mimic asthma symptoms, especially in acute settings.
- Identifying complications like pneumonia or pneumothorax.
- In persistent symptoms unresponsive to treatment, a chest CT scan may be recommended for a more detailed evaluation.
5. Spirometry: Spirometry is the preferred diagnostic test for asthma, measuring lung function. It can:
- Detect obstructive patterns characteristic of asthma.
- Assess reversibility of airflow obstruction after bronchodilator administration (e.g., salbutamol).
- Gauge disease severity before initiating treatment and monitor treatment effectiveness over time.
6. Allergy Testing: Allergy testing helps identify specific triggers, guiding avoidance strategies and targeted treatment. Methods include:
- Skin prick tests.
- Blood radioallergosorbent tests (RAST) or specific IgE tests, which identify common allergens like dust mites, pet dander, or pollen.
Alt: Spirometry test in progress, a key diagnostic tool for assessing lung function and asthma severity.
Nursing Interventions for Asthma
Nursing interventions are crucial for managing asthma symptoms, both acutely and in the long term.
Managing Acute Asthma Symptoms
1. Albuterol Administration: For acute exacerbations, inhaled beta2 agonists like albuterol are the first-line treatment, providing rapid bronchodilation.
- Administer immediately at the onset of symptoms.
- Doses can be repeated up to three times initially, then every 1-4 hours as needed, based on severity and response.
2. Oxygen Therapy: Supplemental oxygen is vital for patients with hypoxia during an asthma attack.
- Administer oxygen via nasal cannula or face mask as prescribed, guided by SpO2 levels and ABG results.
- Adjust flow rate to maintain adequate oxygen saturation.
3. Corticosteroid Administration: Corticosteroids reduce airway inflammation and prevent late-phase responses in asthma exacerbations.
- Administer oral steroids, which are as effective as IV steroids for most exacerbations, simplifying treatment and allowing for outpatient management in many cases.
- IV steroids may be used in severe cases or when oral intake is compromised.
4. Hospitalization Preparedness: Decisions regarding hospitalization depend on exacerbation severity, duration, and patient factors.
-
Hospital admission may be necessary based on:
- Severity and duration of symptoms.
- History of severe exacerbations.
- Ability to adhere to medication regimen at home.
- Adequacy of home support system.
-
ICU admission is indicated if:
- Condition worsens despite initial treatment.
- Change in mental status occurs.
- Respiratory arrest is imminent or occurs.
- Intubation and mechanical ventilation are required.
5. Alternative Therapies: Consider alternative and adjunctive therapies for patients with specific needs:
- Allergen immunotherapy (allergy shots): for patients with identified allergen triggers where conventional medications are insufficient.
- Monoclonal antibody treatments (e.g., anti-IgE therapy): for moderate to severe allergic asthma, reducing IgE levels and histamine release.
- Bronchial thermoplasty: a bronchoscopic procedure applying thermal energy to airway walls to reduce airway smooth muscle mass and constriction.
Preventing Future Asthma Exacerbations
