Technological advances in monitoring have at least a theoretical risk of exceeding our ability to understand the clinical implications of the derived information. This could result in the use of monitoring data to make inappropriate clinical decisions. Therefore, the implementation of any new monitoring technology must take into account the relevance and accuracy of the data obtained, the risks to the patient, and the evidence supporting any intervention directed at correcting the detected abnormality. The routine use of invasive monitoring devices, specifically the pulmonary artery catheter, must be questioned in light of the available evidence that does not demonstrate a clear benefit to its widespread use in various populations of critically ill patients. The future of physiologic monitoring will be dominated by the application of noninvasive and highly accurate devices which guide evidenced-based therapy.
