Peak inspiratory flow rate and slope of the inhalation profiles in dry powder inhalers.
Aerosol delivery depends on device design and inhalation technique. In vitro device evaluations have shown that the emitted dose and fine particle mass of dry powder inhalers (DPIs) increase at high peak inspiratory flow rates (PIFR). Since the PIFR is mostly achieved after the release of the powder, slope of the pressure profile is also described as an important determinant. The aim of the pre...
متن کاملAssessment of inhalation flow patterns of soft mist inhaler co-prescribed with dry powder inhaler using inspiratory flow meter for multi inhalation devices
The patients' inhalation flow pattern is one of the significant determinants for clinical performance of inhalation therapy. However, the development of inhalation flow meters for various inhalation devices has been unable to keep up with the increasing number of newly launched inhalation devices. In the present study, we developed simple attachment orifices for the inhalation flow pattern moni...
متن کامل[Measurement of inspiratory flow for the selection of the inhalation treatment device for asthma and COPD].
AIM To assess the proportion of patients with asthma or chronic obstructive pulmonary disease (COPD) with significant bronchoobstruction who do not have inspiratory flows necessary for the adequate use of dry powder inhaler (DPI) devices Diskus and Turbuhaler. PATIENTS AND METHODS multicentre cross-sectional study that included 400 patients with asthma or COPD (with FEV1 < 60%) aged 5-91 year...
متن کاملNew inhalation devices.
ll is now accepted that inhaled bronchodilator therapy is, whenever possible, to be preferred to oral treatment in the routine management of reversible airflow obstruction [1). However, during the last two decades we have repeatedly been reminded that many patients have great difficulty in using the conventional pressurized metered dose inhaler (MDI) [2-6], today's most frequently prescribed in...
متن کاملSelecting Devices for Aggregation
As intelligent devices become affordable and wireless infrastructure becomes pervasive, the potential to combine, or aggregate, device functionality to provide a user with a better experience grows. Often, there will be multiple devices providing similar functionality that the user will have to choose from for the aggregation. This paper presents the design and prototype implementation of a sys...
