Fluid balance is essential for normal functioning of the body. Oliguria (poor urine output) is usually associated with low circulatory blood volume (hypovolaemia), and can be a sign that a patient is acutely ill and deteriorating. Early warning scoring systems should identify the condition so that appropriate interventions can be undertaken to restore urine output and protect renal function.
体液平衡对于身体的正常功能至关重要。少尿（尿量少）通常与循环血容量低（血容量不足）有关，可能是患者病情危急且正在恶化的迹象。早期预警评分系统应识别出这种情况，以便能够采取适当的干预措施来恢复尿量并保护肾功能。
