OBJECTIVE
Arterial pulse pressure variation (PPV) has been used as an accurate index to predict fluid responsiveness. However, many confounding factors have been recently described. The aims of this study were to assess the conditions of applicability of PPV in intensive care units (ICU).
STUDY DESIGN
A one-day French national survey.
PATIENTS AND METHODS
A form assessing the suitability of PPV was completed by practitioners for each critically-ill patient included on a set day.
RESULTS
Four hundred and sixty-five patients were included in 36 ICUs. A regular sinus rhythm was noted in 408 (88%) patients and the presence of an arterial line in 324 (70%) patients. One hundred and twenty-seven (27%) patients were mechanically ventilated without spontaneous breathing. Only six patients (1.3%) had no confounding factors modifying the threshold value of the PPV.
CONCLUSION
The incidence of ICU patients in whom PPV was suitable and without confounding factors were respectively 18% and 1.3% in this one-day French national survey.
目的
动脉脉搏压变异度（PPV）已被用作预测液体反应性的准确指标。然而，最近已经描述了许多混杂因素。本研究的目的是评估在重症监护病房（ICU）中应用 PPV 的条件。
研究设计
一项为期一天的法国全国性调查。
患者和方法
在规定的一天内，每位纳入的危重症患者的临床医生都填写一份评估 PPV 适用性的表格。
结果
36 个 ICU 共纳入 465 名患者。408 名（88%）患者为窦性节律，324 名（70%）患者有动脉置管。127 名（27%）患者接受机械通气而无自主呼吸。仅有 6 名患者（1.3%）无改变 PPV 阈值的混杂因素。
结论
在这项为期一天的法国全国性调查中，适合使用 PPV 且无混杂因素的 ICU 患者的发生率分别为 18%和 1.3%。
