The use of a spacer is especially beneficial for patients with advanced COPD. Most cannot inhale deeply and suffer from poor lung function. This makes it very difficult to breathe the medication deep into the small airways. However, a spacer makes this possible.
The lungs of COPD patients are often sensitive and slightly irritated, which makes patients more likely to have coughing fits after spray inhalation. An inhalation chamber soothes the irritation and patients can inhale without the unpleasant cough.
At a certain age, it can also be difficult for patients to coordinate pressing the spray trigger while breathing in at the same time. A spacer can help here too. The spray reaches the bronchial tubes properly.
