The nurse is educating a patient regarding breathing techniques. what technique should the nurse avoid in a patient with chronic obstructive pulmonary disease (copd) who has marked hyperinflation?

The breathing technique that should be avoided in patients with chronic obstructive pulmonary disease is diaphragmatic breathing. Diaphragmatic breathing is observed as the rise and fall of the abdomen instead of the chest. This should be avoided as this increases the work of breathing. 

Breathing techniques that can be employed include yoga and pursed-lip breathing.
