During floods, the Malaysian Department of Welfare (JKM) oversees opening and assigning victims to evacuation centres. Public buildings such as school classrooms community halls act Temporary Evacuation Centers (TEC) that can last up two weeks. The foldable tents will be provided each family at centres assure have personal space. For privacy separation, they were confined in a temporary tent wi...
Computational fluid dynamics as surgical planning tool: a pilot study on middle turbinate resection.
Controversies exist regarding the resection or preservation of the middle turbinate (MT) during functional endoscopic sinus surgery. Any MT resection will perturb nasal airflow and may affect the mucociliary dynamics of the osteomeatal complex. Neither rhinometry nor computed tomography (CT) can adequately quantify nasal airflow pattern changes following surgery. This study explores the feasibi...
Rehabilitation after laryngectomy includes more and more the use of airflow-regulating devices such as shunt valves (SVs), tracheostoma valves (TSVs), and heat and moisture exchange (HME) filters. In determining the quality of those devices, airflow resistance is a very important factor. It is currently defined as pressure drop divided by airflow. However, for most applications, this definition...
PURPOSE There are still evidence gaps on the prevalence of airflow limitation in Japan. The purpose of this survey was to estimate the prevalence of airflow limitation among healthy subjects in Japan and to show what proportion of subjects with airflow limitation had been diagnosed with chronic obstructive pulmonary disease (COPD). SUBJECTS AND METHODS This was an observational, cross-section...
STUDY OBJECTIVE To investigate the distribution of reduction in lean body mass (LBM) and whether LBM in legs (LBMlegs) can be a determinant of maximal exercise performance in COPD patients. METHODS Thirty-eight male outpatients with COPD (mean +/- SD FEV1, 47.4 +/- 24.0% of predicted) who underwent complete pulmonary function testing were classified into two groups according to FEV1 expressed...
BACKGROUND Chronic obstructive pulmonary disease (COPD) is considered to be a respiratory disease with systemic manifestations. Some multidimensional staging systems, not based solely on the level of airflow limitation, have been developed; however, these systems have rarely been compared. METHODS We previously recruited 150 male outpatients with COPD for an analysis of factors related to mor...
11 Currently there exists no generally accepted reference technique to measure the ventilation rate 12 through naturally ventilated (NV) vents. This has an impact on the reliability of airflow rate control 13 techniques and emission rate measurements in NV animal houses. As an attempt to address this issue a 14 NV test facility was built to develop new airflow rate measurement techniques for bo...
