The growing utilization of critical care echocardiography (CCE) by clinicians necessitates a meticulous review of clinical conditions in critically ill patients, both before and during the examination. The reviewing process of clinical conditions minimizes the risk of overlooking or misinterpreting crucial findings. This article proposes a comprehensive strategy, namely BILL strategy to integrated into the CCE protocol, where “B” represents baseline respiratory and hemodynamic support, “I” signifies information gleaned from invasive monitoring, including central venous pressure and thermodilution-derived cardiac output, the first “L” denotes laboratory results such as central venous oxygen saturation, troponin, and brain natriuretic peptide, and the second “L” refers to lung ultrasound data. xx Combining the BILL strategy with CCE enhances a more comprehensive understanding of critical illness, potentially leading to improved diagnostic accuracy and patient outcomes.
