Trial Parameters
Brief Summary
The goal of this observational study is to define the safe distance that will reduce the risk of pneumothorax through ultrasonographic imaging measurements in both sitting and prone positions to ensure patient safety during these procedures. The main question\[s\] it aims to answer \[is/are\]: The mean distance between the skin and pleura in sitting position during the inhalation and exhalation The mean distance between the skin and pleura in prone position during the inhalation and exhalation
