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、氧减饱和度及脉搏频率的影响。主要结果如下：虽然正常受试者的呼吸模式调节良好，但残疾受试者的呼吸模式却多种多样。至于体位与呼吸周期的关系，正常组10度体位的呼吸周期持续时间明显长于45度体位。另一方面，残疾受试者显示，在3名患者中，有2名患者45度体位的呼吸周期持续时间长于10度体位。无论是正常人还是残疾人，吞咽10度体位时的SpO2均高于45度体位。正常人10度卧位的静息和吞咽脉率低于45度卧位。

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.
