| [ Summary ] | We set a vertical tube in blood tubing to read the blood level and have been developing adevice to measure BP with corrections for the noise caused by dialysis machines. Our bovine blood experiment shows that mimiced BP is directly proportional to that inside of arterial blood tubing, which suggests the possibility of useing this interior pressure to measure BP. We measured four patients'BP 160 times using normal sphygmomanometry and found two patients out of four showed correlations between these factors. Two patients showed no relationship. They were those whose BP reduction rate was less than 20%. Taking into consideration the facts concerning blood vessel rigidity and blood density. we will proceed with this study. |
