Size Distribution of Particles from Inhalers - Influence of Inspiratory Flow Rate and Humidity.
Ondráčková, Lucie ; Ondráček, Jakub ; Kozáková, Jana ; Ždímal, Vladimír
The purpose of this research was to determine the influence of inspiratory flow rate and relative humidity on particle size distributions (PSDs) generated by three MDI inhalers (Flutiform, Fullhale and Ventolin) and one DPI inhaler (Spiriva). Particle size distributions were measured by APS 3321 (TSI, USA) for three different inspiratory flow rates – 30, 60 and 90 l/min. Hygroscopicity of particles was determined by comparing data obtained at laboratory conditions and at relative humidity of 90%. During the measurements of number PSDs by using of APS spectrometer, we recorded bimodal distributions for Flutiform and Fullhale and monomodal distributions for Ventolin and DPI Spiriva. The increasing inspiratory flow rate had a negligible effect on the position of modes of individual distributions. The differences in PSD, measured under ambient conditions and at RH of 90%, were also minimal and did not significantly affect the assumed probability of drug deposition.

Problems of patients with long-term cardiac support
Ondráčková, Lucie ; Pavlíková, Pavla (advisor) ; Černá, Alena (referee)
Bachelor thesis is divided into theoretical and empirical part. The theoretical part is devoted to heart failure, given that it is patients with end stage heart failure is a long-term cardiac support implemented. It is described surgical treatment of heart failure and various cardiac support. A separate section is devoted to long-term cardiac support-Heart Mate II. Conclusion The theoretical part is devoted to the specifics of treatment of patients with established long-term cardiac support. The empirical part of the paper maps out the problems of patients with established long- term cardiac support. The method used to implement the survey questionnaire. The studied group consisted of 21 patients with established long-term cardiac support in outpatient care. Reconnaissance survey conducted in the outpatient department of heart failure IKEM in Prague. The work shows that although the introduction of cardiac support for patients and mentally demanding affects their daily life, most of them feel improvements in your health and well-established cardiac support perceived as a chance to wait for a heart transplant.

Environmental ultrafine particles (UP or PM0.1) were investigated at the roadside of Syuefu road in Hsinchu city and in Syueshan highway tunnel in Taipei, Taiwan. For comparison purpose, coarse (PM10-2.5) and fine (PM2.5) particles were also studied at the same time. A SMPS (TSI 3936), three Dichotomous samplers (Andersen SA-241) and three MOUDIs (MPS110) were deployed simultaneously at the field conditions to determine the mass concentrations and number concentrations and the filter samples were further analyzed for organic carbon (OC), element carbon (EC), water-soluble ions and trace elements.
