Background: Weaning from mechanical ventilation in the intensive care unit is an important step in the treatment process. More patients in less than 6 hours after cardiac surgery can be separated from mechanical ventilation and extubated. However, 20-40% of patients after cardiac surgery, due to dysfunctional ventilator weaning response (DVWR), still remain under mechanical ventilation. Therefo...
Background and Objectives: Increasing the concentration of carbon dioxide (CO2) leads to reduced comfort and learning disruption. Therefore, the present study was conducted to determine the concentration of CO2 in classrooms of Babol and Gonabad cities and its relationship with classroom ventilation and temperature. Materials and Methods: This descriptive study was randomly carried out in spr...
Buildings and their related activities are responsible for a large portion of the energy consumed in China. It is therefore worthwhile to improve the energy efficiency of buildings. This paper describes a low energy building design in Hangzhou, south China. A hybrid ventilation system which employs both natural and mechanical ventilation was used for the building due to the severity of the clim...
Operation Theatre (OT) is the most important area where precise controlled on indoor air quality is required because it is directly related to patient health and its recovery period. This work aims to study and visualize the airflow distribution of conventional flat air diffuser ventilation system and newly designed angular air ventilation system in OT. Angular Air Distribution (AAD) system is ...
Abstract Aim. The aim of this study was to examine the effect of protocol of weaning from mechanical ventilation on the gastrointestinal function in people undergoing CABG. Background. The most common problems after cardiac surgery in the intensive care unit are change in vital signs, respiratory problems, unsuccessful separation from mechanical ventilation, and gastrointestinal problems. Due t...
Abstract: Mine ventilation system is critical for maintaining safe working conditions in an underground coal mine. At present, there exist some problems in developing mine ventilation software such as long development cycle, redevelopment, low commercialization and weak extensibility. The traditional digital mine ventilation systems is complicated to be modified or extended after published unle...
