ABSTRACT
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 .
