ABSTRACT

Purpose of the study: To know the physiologic background and the future perspective of the dynamic hemodynamic monitoring devices since the static hemodynamic monitoring does not provide continuous cardiac output assessment and has not proven to have any impact on survival or outcome of critical patients. Methods: We conducted an exhaustive bibliographical review on Medline about dynamic monitoring devices in the last 5 years. Results: Nowadays dynamic variables such as systolic pressure variation, pulse pressure variation and stroke volume variation can be assessed by dynamic monitoring and have proven to be good predictors of response to preload in critical care patients under mechanical ventilation. Until now circulatory shock and responses to preload therapy are the main uses of dynamic monitoring devices since they predict and measure the response to fluid resuscitation and the variations in cardiac output produced by therapeutic interventions. Conclusions: Although future is promising, further randomized controlled trials need to be conducted in order to know the strength and weaknesses of these devices.
