Effects of positioning of head/neck and trunk on respiratory cycle, oxygen desaturation and pulse rate in feeding.

本研究旨在探讨体位对吞咽时呼吸运动、氧减饱和度和脉搏率的影响，主要结果如下：正常人的呼吸模式有规律，而残疾人的呼吸模式有变化。在体位与呼吸周期的关系方面，正常组10 °体位呼吸周期持续时间显著长于45 °体位。另一方面，残疾受试者显示，在三分之二的患者中，45度位置的呼吸周期的持续时间长于10度位置。无论是正常人还是残疾人，10 °位吞咽时SpO2均高于45 °位。正常人10 °位静息和吞咽脉率低于45 °位。

The purpose of this study was to examine the effects of positioning on respiratory movement, oxygen desaturation and pulse rate during swallowing.The main results were as follows :Although normal subjects showed a well-regulated respiratory pattern, disabled subjects showed variable respiratory pattern. As for the relationship between positioning and respiratory cycle, normal group showed that duration time of a respiratory cycle of 10-degree position was significantly longer than 45-degree position. On the other hand disabled subjects showed that in two out of three patients, duration time of a respiratory cycle of 45-degree position was longer than 10-degree position. Both in normal and disabled subjects, SpO2 during swallowing of 10-degree position was higher than 45-degree position. Resting and swallowing pulse rate of 10-degree position was lower than 45-degree position in normal subjects.
