Among persons with COPD, is pursed lip breathing or diaphragmatic breathing a more effective technique to improve symptoms and efficiency of breathing? Meredith Alvey, Abby Naville, Alex Piedmonte, Lauren Speelman
Factors Analyzed • Respiratory rate • Work of breathing • Dyspnea • Oxygen
Breathing Techniques Pursed Lip Breathing Diaphragmatic Breathing www.st-joseph.kramesonline.com www.my.clevelandclinic.org
Respiratory Rate Pursed Lip Breathing Diaphragmatic Breathing Slowed breathing frequency from 17.3 to 15 (Jones, 2003) Increase in tidal volume (Vitacca, 1997) • Slowed breathing frequency from 17.3 to 12.8 (Jones, 2003) • Lowers oxygen costs (Jones, 2003) • Increased tidal volume (Gosselink, 2004)
Work of Breathing Pursed Lip Breathing Diaphragmatic Breathing Causes respiratory muscle fatigue (Gosselink, 2004) Decrease in mechanical efficiency (Dechman, 2004; Gosselink, 1995) • Often adopted naturally (Dechman, 2004) • Utilizes the subject’s natural inspiratory breathing pattern (Jones, 2003)
Oxygen Pursed Lip Breathing Diaphragmatic Breathing Partial pressure of oxygen increased (Vitacca, 1997) Decreased oxygen consumption compared to spontaneous breathing (Jones, 2003) 165.8 mL/min • Improves oxygen saturation in resting conditions (Gosselink, 2004) • No improvements in blood gases with exercise (Gosselink, 2004) • Decreased oxygen consumption compared to spontaneous breathing (Jones, 2003) • 164.8 mL/min
Dyspnea Pursed Lip Breathing Diaphragmatic Breathing Three studies stated dyspnea increased with this technique Visual analog scale (Vitacca, 1997) 33 to 54 • Two articles reported improvements
Conclusion • Pursed lip breathing is supported over diaphragmatic breathing • Carryover effect • Future studies needed
