Blood pressure measurements by the Keito machine. Evaluation versus office blood pressure by physicians.

摘要: Background The Keito machine offers automatic measurements of blood pressure (BP), height and weight on insertion coins has been introduced in pharmacies. Design Cross-sectional study comparing BP by the to office physicians. Methods Patients scheduled for pre-catheterisation screening participated study. Their was first measured using machine, then Office recorded as last three consecutive with one-min intervals after a five-min rest sitting position. In sub-study simultaneously during measurement physician. Results 390 patients average significantly lower compared made physicians (136/75 ′ 19/8 mmHg versus 141/79 21/10 mmHg, both p<0.001). correlation coefficient (r) 0.56 (p<0.001) systolic (SBP) 0.53 diastolic (DBP). Bland-Altman analysis showed mean difference (′ 2 SD) SBP DBP -5 (′37) -4 17) respectively.
