Objective To investigate the practicality and stability of self -made bedside angle instrument in clinic .Methods 81 cases of mechanical ventilation were randomly divided into the experimental group (n=42) and the control group(n=39) .The bed head in the control group was elevated according to the experience and sensation .However the bed head in the experimental group was elevated by the self-made bedside angle instrument .The bed head elevation angle in the two groups was measured at the differ-ent timepoints .Results The accuracy of bed head elevation was 100% in the experimental group and 57 .69% in the control group , the difference between the two groups had statistical significance (P<0 .05) .Conclusion The bedside angle instrument has good practicality and stability ,effectively ensures the accuracy of the bed head elevation and contributes to conduct the body posture nursing on the patients with mechanical ventilation .%目的：探讨自制床头角度仪的临床实用性和稳定性。方法：将81例机械通气患者随机分为实验组（n＝42）和对照组（n＝39）。实验组采用自制床头角度仪抬高患者床头。对照组依据经验和感觉抬高患者床头。两组床头抬高角度分别在不同时间点进行定时测量。结果实验组床头抬高准确率为100％，而对照组床头抬高准确率为57．69％，两组比较差异有统计学意义（ P＜0．05）。结论：床头角度仪具有良好的临床实用性及稳定性，可有效保证床头抬高角度的准确性，有助于机械通气患者的体位护理。
