Patients with respiratory failure undergoing prone positioning (PP) are often monitored by the transpulmonary thermodilution (TPTD) technique. However, it remains unclear whether the measurement of TPTD-derived variables is influenced by PP. We investigated the effects of 135° PP on the accuracy of TPTD-derived variables and their changes over an 8-10 h ...
