Study Notes
Bronchial Hygiene Therapies: Key Points
- Atelectasis is used as prophylaxis against postoperative pulmonary complications and as part of bronchial hygiene in various respiratory conditions
- Contraindications to manually assisted directed cough include elevated intracranial pressure, reduced coronary artery perfusion, and acute unstable head or spine injury
- Complications of bronchial hygiene therapies include reduced coronary and cerebral perfusion, incontinence, fatigue, headache, and bronchospasm
- Assessment of need for bronchial hygiene therapies includes ineffective spontaneous cough, evidence of atelectasis, and postoperative patients
- Prone positioning is used to improve oxygenation and V/Q mismatch
- Forced expiratory technique (FET), active cycle breathing, autogenic drainage, and insufflation and exsufflation are bronchial hygiene techniques
- Turning is contraindicated in unstable spinal cord injuries and relative contraindications include diarrhea and increased intracranial pressure
- Positive airway pressure adjuncts are used to reduce air trapping, mobilize secretions, prevent atelectasis, and optimize bronchodilator delivery
- Complications of positive airway pressure adjuncts include increased work of breathing, cardiovascular compromise, and air swallowing
- Assessment of need for positive airway pressure adjuncts includes sputum retention, abnormal chest x-ray, and indications of respiratory distress
- Positive outcomes of positive airway pressure adjuncts include increased sputum production, improvement in breath sounds, and positive subjective response
- High-frequency chest wall oscillation (HFCWO), intrapulmonary percussive ventilation (IPV), and flutter valve are bronchial hygiene techniques with specific delivery methods and frequencies
