My name is Professor Azriel Perel, and I'm from Tel Aviv in Israel. In my presentation, I addressed the challenge of accurately interpreting the numerous parameters displayed on our monitors. While modern monitoring systems provide a wealth of data, not all of these parameters are equally reliable—some can be quite inaccurate. My aim was to bring clarity to this issue by highlighting the limitations of certain measurements and proposing practical strategies for navigating these inaccuracies. Ultimately, I focused on how to make sound clinical decisions despite the presence of potentially misleading information.
