Modelová pomůcka - Bubble CPAP

Abstract

Newborn respiratory distress syndrome (NRDS) is one of the most common cause in neonatal deaths. The widely used method to solve NRDS is ventilation. Ventilation method can be 2 types: invasive and non-invasive. Invasive method is effective, however very expensive and requires trained personnel to use and maintain it. Bubble CPAP is non-invasive, simple, effective, and low-cost device. This bachelor thesis aims to develop the teaching tool bubble CPAP for demonstration in study purposes and future modification. Designed bubble CPAP is able to control the flow from flow mass controller and read the pressure oscillations. Control of flow and reading of the pressure values are performed with help of Simulink software. The work also compared the influence of the flow and depth of immersion of expiratory tube on the pressure oscillations created by bubbles in water column. Due to limitations in hardware, the designed bubble CPAP is not able correctly interpret the high-frequency pressure oscillations. Even though, the designed project is able to demonstrate main principles and patterns of the bubble CPAP.
