Comparison of Korotkoff blood pressure measuring method and invasive blood pressure measuring method in shock patients at the age of over 16 years, treated in Bach Mai hospital from June 2004 to November 2004. The results: the Korotkoff method in shock patients showed less accurate outcome and higher errors of measurement than the invasive method. When systolic blood pressure <70mmHg or mean blood pressure <40mmHg, the errors of measurement between 2 methods increased 2 folds. In shock patients, the accuracy of the Korotkoff method gained acceptable level when systolic blood pressure ≥60mmHg
