据卫生部、国家医药管理局、国家计量局在联合发出的通知中指出,将废除毫米汞柱(mmHg)体液压力单位,而代之以国际单位制的单位千帕斯卡(KPa)。其换算关系是:1mmHg=0.133322KPa如正常成人的收缩压一般不超过140mmHg,换制后应计为不超过18.7KPa。舒张压应为90mmHg以下,计为12.0KPa以下。因人体静脉压较低,有时以毫米水柱(mmH_2O)
According to a joint circular issued by the Ministry of Health, the State Pharmaceutical Administration and the National Bureau of Metrology, it is stated that body pressure units of millimeters of mercury (mmHg) will be abolished and replaced by units of kilo-Pascal (KPa) in the International System of Units. The conversion is: 1mmHg = 0.133322KPa normal adult systolic blood pressure generally does not exceed 140mmHg, after the conversion should be considered not more than 18.7KPa. Diastolic blood pressure should be below 90mmHg, calculated as 12.0KPa or less. Due to the lower body pressure, sometimes in mm water column (mmH_2O)
