Therapeutic Breathing Techniques for Cardiopulmonary Care
Key Points
- Diaphragmatic breathing helps reduce tachypnea and anxiety-linked overbreathing.
- Pursed-lip breathing prolongs exhalation and supports airway patency.
- Incentive spirometry is used to prevent and treat atelectasis, especially postoperatively.
- Coughing and deep breathing mobilize secretions and support pneumonia prevention.
Pathophysiology
Impaired breathing patterns and shallow ventilation increase risk of alveolar collapse, secretion retention, and worsening gas exchange. Nurse-taught breathing techniques improve respiratory mechanics and can interrupt dyspnea-anxiety cycles that worsen work of breathing.
Diaphragmatic and pursed-lip breathing improve control of ventilation, while incentive spirometry and structured cough-deep-breathing promote alveolar recruitment and secretion clearance.
Classification
- Diaphragmatic breathing: Redirects effort from upper chest breathing to diaphragmatic expansion.
- Pursed-lip breathing: Nasal inspiration with slow, controlled exhalation through pursed lips.
- Incentive spirometry: Slow deep inhalation with inspiratory hold, commonly ten times hourly while awake.
- Cough and deep breathing: Repeated deep breaths followed by cough, typically three to five times hourly.
Nursing Assessment
NCLEX Focus
Priorities include identifying ineffective breathing patterns early and selecting the most appropriate coached technique.
- Assess baseline respiratory rate, effort, and dyspnea pattern.
- Assess whether anxiety contributes to hyperventilation or tachypnea.
- Assess patient ability to perform technique correctly and consistently.
- Assess response trends, including respiratory comfort, fever trajectory, and secretion clearance.
Nursing Interventions
- Teach one technique at a time with return demonstration and coached repetition.
- For incentive spirometry, reinforce upright position, slow inhalation, brief inspiratory hold, and hourly frequency while awake.
- Document completion frequency and performance quality when tasks are delegated.
- Use pain-control timing and repositioning to improve participation in breathing exercises.
- Reinforce rationale to improve adherence and reduce postoperative pulmonary complications.
Underuse Risk
Inconsistent breathing-exercise performance can increase atelectasis and secondary pulmonary infection risk.
Pharmacology
Adjunct anxiolytic therapy may be considered when anxiety significantly impairs breathing control; medication support does not replace technique coaching and reassessment.
Clinical Judgment Application
Clinical Scenario
A postoperative patient shows low-grade fever and shallow breathing after inconsistent use of incentive spirometry.
Recognize Cues: Reduced deep-breathing participation and rising temperature suggest impaired pulmonary toilet. Analyze Cues: Atelectatic change risk is increasing due to insufficient alveolar expansion. Prioritize Hypotheses: Breathing-technique adherence is the immediate modifiable driver. Generate Solutions: Pair analgesia with coached IS and cough-deep-breathing intervals. Take Action: Resume structured hourly breathing interventions and document response. Evaluate Outcomes: Fever trend and breathing comfort improve with consistent technique use.
