The aim of this work consists of the description of the technique and the methodology used to acquire pleural pressure measurement data in order to explore the distribution of the pressure inside the chest during the tests.
To reach the aim, a specially designed device named Pleural Pressure System (PPS) was developed in order to measure the pressure inside the pleural cavity during the tests and consequently to get data on the external parenchyma pressure of the lung.
The effects of the acceleration on the device including a standard sensor are compared to the data obtained in the same condition with an isolated standard sensor in order to validate the measurement data acquired during the tests.
The methodology used to install the modified sensor is described. The results obtained during dynamic tests are presented.
In conclusion, this validated device shows a difference between the external parenchyma pressure of the lung and the tracheal pressure during the tests. These data could allow a better understanding of certain injury mechanisms and could be used for a future evolution of a numerical model.
