目的 :研究健康航海人员 2 4h动态血压监测 (ABPM )各参数变化规律 ,从中得出各参数的正常参照值。方法 :测量 10 0例健康航海人员左上臂坐位血压 (<140 / 90mmHg ,1mmHg =0 .133kPa) ,行 2 4hABPM。结果 :10 0例健康航海人员ABPM各参数均值 (上限值 )分别为 :2 4h动态血压均值 (116 .2～ 12 7.8) / (75 .0～ 83.6 )mmHg ;日间血压均值 (119.2～ 131.6 ) / (76 .8～86 .0 )mmHg ;夜间血压均值 (10 5 .5～ 119.9) / (6 6 .0～ 77.8)mmHg。血压波动范围收缩压大于舒张压 ,白天大于夜间。夜间血压下降率在 11%～ 15 %。血压负荷值收缩压为 5 %～ 15 %,舒张压 8%～ 12 %。结论 :建议 2 4h动态血压均值 <12 8/ 84mmHg ,日间血压均值 <132 / 86mmHg ,夜间血压均值 <12 0 / 78mmHg ,夜间血压下降率≥ 10 %,血压负荷值 <15 %作为暂定健康航海人员2 4h动态血压正常参照值标准。
OBJECTIVE: To study the changes of various parameters of 24-hour ambulatory blood pressure monitoring (ABPM) for healthy sailors, and derive the normal reference value of each parameter. Methods: Blood pressure (<140 / 90mmHg, 1mmHg = 0.133kPa) was measured in the left upper arm of 100 healthy sailing crew members and was performed for 24 hABPM. Results: The mean (upper limit) values of ABPM for all 10 healthy sailors were respectively: 24 h ambulatory blood pressure (116.2 ~ 12.88) / (75.0-083.6) mmHg, mean daytime blood pressure (119.2 ~ 131.6) / (76.8 ~ 86.0) mmHg; mean nocturnal blood pressure (105.5-119.9) / (6.60-77.8) mmHg. Blood pressure fluctuation range systolic blood pressure greater than diastolic blood pressure during the day than at night. Night blood pressure decreased at 11% to 15%. Blood pressure load systolic blood pressure of 5% to 15%, diastolic blood pressure of 8% to 12%. Conclusion: It is suggested that the mean value of ambulatory blood pressure is <12 8 / 84mmHg at 24 hours, mean daytime blood pressure <132 / 86mmHg, mean nighttime blood pressure <12 0/78 mmHg, nighttime blood pressure declining rate≥10% and blood pressure load <15% 2 4h navigation personnel ambulatory blood pressure normal reference standard.
