Inhaled particle deposition and body habitus.
As a result of the intrapleural pressure gradient that exists in the human lung, both ventilation and particle deposition increase from apex to base. Since the intrapleural gradient varies with the height of the subject, it was decided to compare regional particle deposition in tall, short, and obese subjects to ascertain whether it was influenced by height and weight. Surprisingly, deposition ...

متن کاملBody habitus changes related to lipodystrophy.
Changes in body fat in persons infected with the human immunodeficiency virus (HIV) have been associated with deleterious changes in blood lipids and insulin resistance, raising concern that these changes will increase the risk for accelerated atherosclerosis. Changes in body fat are often identified in advanced disease but may also occur early after HIV infection is detected. Conflicting evide...
متن کاملEffect of inhaled dust mite allergen on regional particle deposition and mucociliary clearance in allergic asthmatics.
BACKGROUND Acute exacerbations in allergic asthmatics may lead to impaired ability to clear mucus from the airways, a key factor in asthma morbidity. OBJECTIVE The purpose of this study was to determine the effect of inhaled house dust mite challenge on the regional deposition of inhaled particles and mucociliary clearance (MCC) in allergic asthmatics. METHODS We used gamma scintigraphy (in...
متن کاملStudy on airflow and inhaled particle deposition within realistic human upper respiratory tract
Based on the CT (Computerized Tomography) scanned images of a 19-years-old healthy boy, a realistic geometric model of URT from nasal cavity to the upper six-generation bronchial is rebuilt. To investigate airflow and particle deposition in the obtained realistic human upper respiratory tract, RNG k-ε turbulence model was used to describe the primary flow and particle deposition under three bre...
