We are using life-size mannequins within an education subjects, e.g. “Medical devices” for a demonstration of basic principles of modern clinical devices such as mechanical lung ventilator. Limitation of many simulators is uniformity of its outputs for same input parameters. This paper describes variability of the vital signs of the mannequin when the same scenario was used for different base patients...
Main purpose of this paper is to describe a propose and compile a dynamometric measurement system which would measure the isometric force of a handgrip. Although, in the practice, there have already been the mechanic hand dynamometers which could evaluate only a limited amount of information, precisely the maximum strength of a handgrip, our aim is to compile the full electronic hand dynamometer....
The study analyses the effect of changes in the mechanical parameters of the respiratory system of the mannequin HPS upon its vital functions during mechanical lung ventilation. The study includes experimental verification of optimal ventilator settings to maintain blood gases at normal physiological values for volume and pressure controlled ventilation. The interaction between mechanical parameters...
The study deals with a design of the scenario of administration of total anesthesia on the life-size simulator. Life-size simulator represents the real human patient and it is being used as a learning tool for medical professionals such as anesthesiologists. Induction of full general anesthesia in life-size simulator is performed by scenario designed in HPS6 software. Scenario reflects real clinical...
The objective was to study the behavior of the subsystems of life-size simulator HPS during spontaneous and assisted ventilation. Demonstration of the assisted ventilation on the mannequin with the use of lung simulator ASL5000 is described. The scenario for a mannequin was designed to simulate an apnea and technical realization of connection of the mannequin and lung simulator is also described....
Mechanical ventilation is used during respiratory failure in many patients. High-frequency oscillatory ventilation is used as a rescue therapy at adult patients. High-frequency ventilation has minimum monitoring and even tidal volume is not routinely measured. Models of the respiratory system can contribute to better understanding about principle of high-frequency oscillatory ventilation. The identification...
The aim of the work was to design a metabolic simulator of the human respiratory system consuming oxygen and producing carbon dioxide. The respiratory quotient, tidal volume, mechanical parameters of the system and other parameters should be similar to the physiological values in (healthy) men so that the simulator could be used for simulation of artificial ventilation of real patients. The model...
Acute respiratory distress syndrome (ARDS) is an acute severe lung disease commonly encountered in intensive care units. High-frequency oscillatory ventilation (HFOV) could offer effective lung protective ventilation by delivering very low tidal volumes around constant relatively higher continuous distending pressure (CDP) at frequencies of 3 to 15 Hz. Optimization of CDP is not an easy task and it...
This Study deals with a development of a virtual patient monitor for a mannequin. We have included the virtual patient simulator into the education and we have developed the application of software monitor to increase the interest of the students about the exercises. The application is developed for a PC tablet and the data of vital functions, such as heart rate, saturation of blood by oxygen, partial...
Design of a mathematical model of the respiratory system and its personification is described in this study. The aim of authors is to develop a model of the respiratory system that will respect anatomical structure of the bronchial tree including its asymmetry. Inclusion of airway asymmetry into the model allows more authentic description of the respiratory system. The model is designed using electro-acoustic...
The miniaturalisation of technical devices enabled the creation of interactive newborn simulator devices. These simulators are primarily designed for pediatricians and neonatologists and for all health care personnel of these respective ward units. Individuals as well as whole teams may train approaches in various simulated situations and thus improve their practical skills. Special criteria and methods...
Interactive patient simulators are more used during the education of healthcare professionals but also in the education of other professionals in the healthcare, e.g. biomedical engineer. The main advantage of interactive simulators is practical education focused on the simulation of real acute life-threatening situations that cannot be simulated on the real human patients mainly from the ethic reason...
