Abstract
Understanding of chest imaging is paramount in the diagnosis and treatment of PARDS and, as recommended by the consensus conference on PARDS (PALICC), children with or at risk of PARDS should receive, at a minimum, clinical monitoring of cardiac and respiratory rates, continuous pulse oximetry, and blood pressure. In the first part of this chapter, we summarize the role of each imaging modality in the diagnosis of PARDS and as a tool of treatment effect examination perspectives. In the second part of the chapter, we describe and summarize respiratory system variables related to PARDS management, which is particularly derived from measurements in a nonairway circuit, including oxygen parameters, severity scores, and respiratory muscle function. The hemodynamic monitoring in PARDS is out of scope of this chapter.
