Transcutaneous capnometry (tPCOâ‚‚) is a non-invasive method for continuous monitoring of ventilation status. In pediatric intensive care patients, it may reduce the need for repeated arterial or arterialized blood sampling. However, the accuracy of tPCOâ‚‚ may be influenced by factors such as peripheral perfusion, skin temperature, and vasopressor therapy. This prospective observational study compares transcutaneous carbon dioxide measurements with arterialized or arterial blood gas PaCOâ‚‚ values in children with respiratory insufficiency, including a subgroup receiving vasopressor support.
