The purpose of this study was to found the way that reduces adverse effect such as hypotension when nurses carried out postural change. In 2010, we reviewed previous studies on this field, and we interviewed nurses to clarify the problems when nurses did the postural change of their patients from supine to standing. The participants mentioned adverse effects (hypotension and arrhythmia) and accidental occurrences (withdrawal of intravenous drips or a catheter retained in the bladder). We did experimental study of elderly person on the next step. We measured forehead blood fl ow, contentious blood pressure, electrocardiogram, and the body movement of participants by using an accelerometer. When participants stood up from supine position, the change ratio of oxygenated hemoglobin quickly dropped from the base line which calculated at supine position. On the other hand, the change ratio of reduced hemoglobin showed increase immediately. There was significant difference between average value of oxygenated hemoglobin at supine and its average value at 30 seconds after standing (p<0.05).

这项研究的目的是找到减少不良影响的方式，例如护士进行姿势变化时的低血压。在2010年，我们审查了以前关于该领域的研究，并采访了护士，以阐明护士从仰卧为患者的姿势变化时的问题。参与者提到不良反应（低血压和心律不齐）和意外发生（静脉滴落或保留在膀胱中的导管）。我们在下一步进行了老年人的实验研究。我们通过使用加速度计测量了额头血压，有争议的血压，心电图和参与者的身体运动。当参与者从仰卧位站起来时，氧化血红蛋白的变化比很快从在仰卧位计算的基线下降。另一方面，减少血红蛋白的变化比立即显示出增加。站立后30秒的氧合血红蛋白的平均值与其平均值之间存在显着差异（p <0.05）。
