Abstract:
Objective To investigate the linear relationship between invasive blood pressure and noninvasive blood pressure,providing references for clinical blood pressure monitoring.Methods Totals of 32 ICU patients were chosen,and their invasive blood pressure and non-invasive blood pressure were monitored at the same time by self-reflection methods.The data were collected and compared,and linear correlation was analyzed.Results Totals of 98 pairs of valid date were collected.The invasive systolic and diastolic blood pressure were respectively (146.93 ± 21.426) and (71.32 ± 13.152) mm Hg,higher than the non-invasive systolic and diastolic blood pressure which were (124.02 ± 19.417) and (68.86 ± 15.251) mm Hg,and the differences were statistically significant (t =15.301,3.363,respectively; P <0.05).And there was a linear relation between invasive blood pressure and non-invasive blood pressure (r =0.880,P < 0.05).Conclusions There is statistically significant difference between invasive blood pressure and non-invasive blood pressure,which are not substitutable for each other.And non-invasive blood pressure monitoring values can be used to deduce and calculate the invasive blood pressure monitoring values.
