Systolic pressure variation and stroke volume variation between spontaneous breathing and mechanical ventilation The present study was aimed at assessing the diagnostic accuracy of ppv for prediction of fluid responsiveness by using the grey zone approach in a large population Fluid responsiveness is also known as “volume responsiveness”
Hemodynamic Pressure Monitoring
Even though there are many ways to determine fluid responsiveness, the only definitive test for fluid responsiveness.
Monitoring arterial pressure variation, i.e
Spv/ppv, helps to answer the question of fluid responsiveness and can be used to guide fluid expansion therapy.4 spv/ppv parameters cannot, however, indicate what type of fluid is the most suitable for the therapy Lidco ltd, as the manufacturer and supplier of pulseco, lidcoplus, lidcorapid and lidcounity medical devices, does not practice medicine and does not recommend these normal parameter metrics for use on a specific patient The medical practitioner who performs any procedure is responsible for determining and utilizing the appropriate techniques, devices and treatments for each individual. The optimal ppv threshold was determined with the youden’s index [19]
In line with a more clinically useful approach that was recently suggested [19, 20, 21] we also adopted a “grey zone”, or two cutoffs, approach to describe the ppv range of values for which formal clinical conclusions cannot be reached. Introduction pulse pressure variation (ppv) has been shown to predict fluid responsiveness in ventilated intensive care unit (icu) patients
