Reliability of Diaphragm Ultrasound: Intra- and Interrater Analysis

It is often difficult for anesthesiologists to select an ultrasound method that will give consistent results and also be a reliable way to examine the diaphragm, especially on the left side of the chest. In this study, two anesthesiologists blinded to one another's scan results, will perform ultrasound scan of the diaphragm using three different methods and the measurements will be analyzed to see the reliability of each method.
