PURPOSE
To study the feasibility and the laterality of measurements of chest wall volume variation during tidal breathing in the lateral position in healthy subjects.
METHODS
Eighteen normal subjects were studied. Chest wall volume changes were measured by optoelectronic plethysmography in the supine and right and left lateral positions during quiet breathing. The accuracy of measuring lung volume was also examined using hot wire spirometry in 10 of the subjects.
RESULTS
The measurement errors between lung volume changes and chest wall volume changes were not significantly different in all positions. There was no significant difference between right and left compartmental volume changes in the supine position. However, chest wall volume changes were lower on the dependent side in the lateral position than on the non-dependent side because of the decrease in abdominal rib cage and abdomen volume changes.
CONCLUSION
Chest wall volume measurements during quiet breathing in the lateral position have high measuring accuracy and show laterality.
目的
研究健康受试者在侧卧位潮气呼吸时胸壁容积变化测量的可行性及测量的左右侧差异。
方法
对18名正常受试者进行研究。在安静呼吸时，通过光电体积描记法测量仰卧位以及右侧和左侧卧位时的胸壁容积变化。还对其中10名受试者使用热线肺量计检查了测量肺容积的准确性。
结果
在所有体位下，肺容积变化与胸壁容积变化之间的测量误差无显著差异。仰卧位时左右肺叶容积变化无显著差异。然而，由于腹侧胸廓和腹部容积变化减少，侧卧位时依赖侧的胸壁容积变化低于非依赖侧。
结论
侧卧位安静呼吸时的胸壁容积测量具有较高的测量准确性，并显示出左右侧差异。
