Comparative Study of Noninvasive Blood Pressure Measurement of Lateral Position and Supine Position

Objective:To investigate whether noninvasive blood pressure measurement of lateral position and supine position was different or not.Methods:Blood pressure measurement of supine position,right lateral position and left lateral position was measured in 150 patients,with noninvasive blood pressure monitoring by the brachial arteries of right upper limbs.Results:The mean systolic pressure of supine position was 128 13±18 97mmHg,that of right lateral position was 127 31±19 60mmHg.There was no significant difference in the two groups, P 0 05.The mean systolic pressure of left lateral position was 113 66±17 69mmHg,which was significant difference with that of supine position, P 0 01.The mean diastolic pressure of supine position was 76 02±12 30mmHg,that of right lateral position was 77 67±12 15mmHg.There was no significant difference in the two groups, P 0 05.The mean diastolic pressure of left lateral position was 61 85±12 21mmHg,which was significant difference with that of supine position, P 0 01.Conclusion:When the brachial arteries of right upper limbs were used for noninvasive blood pressure monitoring of different positions,there was no significant difference between right lateral position and supine position.The mean systolic pressure of left lateral position was 14 47mmHg lower than that of supine,and the mean diastolic pressure was 14 17mmHg lower.
