Abstract：
OBJECTIVE: The aim of this study was to research the effect of different bed head angles on the hemodynamic parameters of intensive care patients lying in the supine position.
METHODS: This study was a non-randomized and non-controlled, quasi-experimental repeated measures study. The study was conducted with 50 intensive care patients aged 18 and over in a general surgery intensive care unit in Turkey. With each patient in the supine position, the bed head was raised to an angle of 0°, 20°, 30°, and 45° without a pillow, and the hemodynamic parameters of central venous pressure, systolic and diastolic blood pressure, heart rate, breathing rate, and peripheral oxygen saturation were recorded after 0 and 10 min.
RESULTS: It was found that the mean central venous pressure value measured at min 0 and 10 was higher when the intensive care patients\' bed head angle was raised to 45° than when the bed head was at an angle of 0° or 20° (p < .05). It was found that the patients\' other hemodynamic parameters were not affected by different bed head angles.
CONCLUSIONS: It was concluded as a result of this research that in intensive care patients in the supine position, only central venous pressure was affected by bed head angle, and that central venous pressure measurement can be reliably made at a bed head angle of 30°.

摘要：
目的：本研究的目的是研究不同床头角度对仰卧位重症监护患者血流动力学参数的影响。
方法：本研究是一项非随机对照研究，准实验重复测量研究。这项研究是在土耳其一家普通外科重症监护室对50名18岁及以上的重症监护患者进行的。每个病人都处于仰卧位，床头升高到0°的角度，20°,30°,45°没有枕头，和中心静脉压的血流动力学参数，收缩压和舒张压,心率,呼吸频率,0和10min后记录外周血氧饱和度。
结果：发现重症监护患者床头角度升高至45°时，在第0和第10分钟测得的平均中心静脉压值高于床头角度为0°或20°时（p<.05）。发现患者的其他血液动力学参数不受不同床头角度的影响。
结论：这项研究的结果得出结论，在仰卧位的重症监护患者中，只有中心静脉压受床头角度的影响，并且可以在30°的床头角度下可靠地进行中心静脉压测量。
