NettetDry powder inhaler (DPI) requires optimal peak inspiratory flow rate (PIFR) for drug delivery. Low PIFR generation is common in the elderly. Patient lung function and intrinsic inhaler resistance are factors for determining generated PIFR and drug delivery from DPI. Objectives: We aimed to identify the PIFR of the older (aged > ... NettetIntroduction: When using a DPI, critical patient inhalation characteristics such as inspiratory flow rate and inhaled volume vary widely between individuals, disease state and severity.

NettetHowever, practical and standardized recommendations for measuring peak inspiratory flow (PIF)-a potential indicator for effective DPI use in chronic obstructive pulmonary disease (COPD)-are lacking. Nettet26. jan. 2024 · A DPI can be considered when the inspiratory flow is sufficient. Preferably, hand–lung coordination is assessed using a placebo device, but as this is often not readily available, this too can be done by judgement of the physician.
