Respiratory alkalosis is a medical condition characterized by decreased carbon dioxide (CO2) levels in the blood due to hyperventilation, resulting in an elevated blood pH above 7.45. This comprehensive nursing diagnosis guide focuses on identifying, treating, and preventing complications associated with respiratory alkalosis.
Causes (Related to)
Respiratory alkalosis can develop due to various physiological and psychological factors:
- Anxiety and panic disorders
- Pain or trauma
- High fever
- Hypoxemia
- Pregnancy
- Central nervous system disorders
- Mechanical ventilation
- High altitude exposure
- Salicylate toxicity
- Pulmonary disorders
- Heat exhaustion
Signs and Symptoms (As evidenced by)
Respiratory alkalosis presents with distinctive clinical manifestations that nurses must recognize for accurate diagnosis and treatment.
Subjective: (Patient reports)
- Lightheadedness
- Dizziness
- Numbness and tingling in extremities
- Anxiety
- Chest pain or tightness
- Confusion
- Shortness of breath
- Palpitations
Objective: (Nurse assesses)
- Increased respiratory rate (>20 breaths/minute)
- Decreased PaCO2 (<35 mmHg)
- Elevated arterial pH (>7.45)
- Rapid, shallow breathing
- Carpopedal spasms
- Tremors
- Decreased serum potassium
- ECG changes
- Decreased serum calcium
Expected Outcomes
The following outcomes indicate successful management of respiratory alkalosis:
- The patient will maintain a normal respiratory rate (12-20 breaths/minute)
- The patient will demonstrate normal arterial blood gas values
- The patient will report reduced anxiety and physical symptoms
- The patient will utilize effective breathing techniques
- The patient will identify and manage triggers
- The patient will maintain stable vital signs
- The patient will return to normal daily activities
Nursing Assessment
Monitor Vital Signs
- Check respiratory rate, pattern, and depth
- Monitor blood pressure and heart rate
- Assess temperature
- Document oxygen saturation
Evaluate Blood Gas Status
- Monitor arterial blood gas results
- Track PaCO2 levels
- Assess pH values
- Document bicarbonate levels
Assess Neurological Status
- Check the level of consciousness
- Monitor for confusion
- Assess peripheral sensation
- Document muscle tension
- Evaluate coordination
Monitor Cardiovascular Status
- Assess heart rhythm
- Check for chest pain
- Monitor peripheral perfusion
- Document ECG changes
Evaluate Psychological Status
- Assess anxiety levels
- Monitor stress factors
- Document coping mechanisms
- Check support systems
Nursing Care Plans
Nursing Care Plan 1: Ineffective Breathing Pattern
Nursing Diagnosis Statement:
Ineffective Breathing Pattern related to anxiety and hyperventilation as evidenced by respiratory rate >24 breaths/minute and decreased PaCO2.
Related Factors:
- Anxiety
- Hyperventilation
- Pain
- Stress response
- Environmental factors
Nursing Interventions and Rationales:
- Coach breathing techniques
Rationale: Promotes normal respiratory pattern and CO2 retention - Implement relaxation techniques
Rationale: Reduces anxiety and helps normalize breathing - Monitor respiratory rate and depth
Rationale: Tracks effectiveness of interventions
Desired Outcomes:
- The patient will maintain a respiratory rate of 12-20 breaths/minute
- The patient will demonstrate effective breathing patterns
- The patient will report decreased anxiety
Nursing Care Plan 2: Anxiety
Nursing Diagnosis Statement:
Anxiety related to the physiological response to respiratory alkalosis as evidenced by expressed feelings of nervousness and increased respiratory rate.
Related Factors:
- Physiological stress
- Chemical imbalance
- Situational crisis
- Fear
- Pain
Nursing Interventions and Rationales:
- Provide calm environment
Rationale: Reduces external stressors - Teach coping strategies
Rationale: Empowers patient to manage anxiety - Monitor anxiety levels
Rationale: Tracks progression and intervention effectiveness
Desired Outcomes:
- The patient will report decreased anxiety
- The patient will utilize effective coping mechanisms
- The patient will maintain a normal respiratory rate
Nursing Care Plan 3: Risk for Electrolyte Imbalance
Nursing Diagnosis Statement:
Risk for Electrolyte Imbalance related to respiratory alkalosis as evidenced by decreased serum calcium and potassium levels.
Related Factors:
- Altered pH
- Increased respiratory rate
- Chemical imbalance
- Nutritional factors
- Medication effects
Nursing Interventions and Rationales:
- Monitor electrolyte levels
Rationale: Identifies imbalances early - Administer supplements as ordered
Rationale: Corrects electrolyte deficiencies - Assess for symptoms of imbalance
Rationale: Enables early intervention
Desired Outcomes:
- The patient will maintain normal electrolyte levels
- The patient will demonstrate no signs of tetany
- The patient will maintain a stable cardiac rhythm
Nursing Care Plan 4: Impaired Gas Exchange
Nursing Diagnosis Statement:
Impaired Gas Exchange related to hyperventilation as evidenced by abnormal arterial blood gases and respiratory alkalosis.
Related Factors:
- Ventilation-perfusion imbalance
- Hyperventilation
- Altered oxygen delivery
- Anxiety
- Pain
Nursing Interventions and Rationales:
- Monitor ABG values
Rationale: Tracks acid-base status - Position for optimal breathing
Rationale: Improves ventilation efficiency - Provide oxygen therapy as ordered
Rationale: Maintains adequate oxygenation
Desired Outcomes:
- The patient will maintain normal blood gas values
- The patient will demonstrate improved gas exchange
- The patient will maintain oxygen saturation >95%
Nursing Care Plan 5: Knowledge Deficit
Nursing Diagnosis Statement:
Knowledge Deficit related to lack of information about respiratory alkalosis as evidenced by questions about condition and management.
Related Factors:
- Limited exposure to information
- Misinterpretation of information
- Lack of resources
- Language barriers
- Cultural factors
Nursing Interventions and Rationales:
- Provide education about the condition
Rationale: Increases understanding and compliance - Teach prevention strategies
Rationale: Empowers patient to prevent a recurrence - Demonstrate breathing techniques
Rationale: Ensures proper technique acquisition
Desired Outcomes:
- The patient will verbalize understanding of the condition
- The patient will demonstrate proper management techniques
- The patient will identify triggers and prevention strategies
