Excerpt
A frequent question in the intensive care setting is whether fluid resuscitation or volume expansion administered to a hypotensive patient will increase that patient’s cardiac output [
1]. In this regard, the assessment of preload, and especially the preload dependency state, is not always simple [
1], specially in case of latent hypovolemia [
2]. Among all indices available, static parameters of preload (central venous pressure, pulmonary artery occlusion pressure), which are influenced by various other physiologic parameters (heart function, heart chamber extramural pressure), do not allow adequate prediction of fluid responsiveness. In contrast, dynamic parameters such as pulse pressure variation (PPV) and stroke volume variation (SVV), which are based on the influence of cardiopulmonary interactions on heart preload, have been found to be accurate indices [
1]. …
