Central venous pressure (CVP) has long been a cornerstone of hemodynamic monitoring, traditionally interpreted as a surrogate of intravascular volume and cardiac preload. Current evidence demonstrates that CVP has limited value as a standalone marker of preload and fluid responsiveness (FR), and its role as a fixed target for fluid resuscitation has progressively declined. This narrative review retraces the evolution of CVP interpretation, from its physiological foundations to its role in contemporary clinical practice. While early resuscitation strategies relied on predefined CVP thresholds, this approach has been abandoned. Despite these limitations, CVP remains widely used due to its simplicity and historical familiarity and modern perspectives instead emphasize its role as a marker of venous congestion. In this context, CVP retains clinical utility when used for waveform interpretation, assessment of venous congestion, and, most importantly, as part of an integrated, multimodal hemodynamic monitoring strategy.
