ABSTRACT
Objective Three common positions have been observed for its influence on the objective indicators of the patients with unilateral lung disease,and the change of subjective symptoms in these patients were collected.Methods The study group consisted of 93 patients who had unilateral lung diseases,each of which was randomly observed for three common positions (healthy side position,affected side position and the horizontal position) for 30 minutes respectively.In these patients,the changes of the objective indictors (heart rate,breathing,blood oxygen saturation,the mean arterial pressure) and subjective symptoms (chest stuffiness,breath is aggravating,etc.) were recorded.Results When using different positions,no statistical difference was observed with the heart rate,breathing,oxygen saturation and mean arterial pressure,whereas when affected side position was taken,the occurrence of worrisome symptoms was obviously higher than the condition when using healthy side position and the horizontal position.There was no statistical difference between the two groups of healthy side position and the horizontal position.Conclusions The occurrence of worrisome symptoms in the case of affected side po-sition is significantly more than the other two positions,indicating that patients with unilateral pulmonary disease are more willing to adopt the healthy side position and the horizontal position.
