Background
Invasive arterial pressure monitoring is a method for measuring blood pressure in an invasive way, can continuously monitor systolic pressure, diastolic pressure and mean arterial pressure, accurately reflect dynamic changes of blood pressure in time, is widely applied to intra-operative monitoring of various critical patients and major operation patients, and is the 'gold standard' for blood pressure measurement. However, the measurement results of the system are often interfered by various factors, and the determination of the treatment scheme and the judgment of the disease prognosis are influenced. Among them, the pressure sensor fixing and zero calibration height is one of the important factors affecting blood pressure monitoring. The clinical level of the heart, i.e. the intersection between the axillary midline and the 4 th intercostal, is used as the indicator for zeroing. Research shows that in the process of pressure measurement, when the height of a pressure sensor is lower than the heart level, both systolic pressure and diastolic pressure rise; when the pressure sensor is high above the heart level, both the systolic and diastolic pressures drop. In interventional therapy, such as coronary artery PCI, TAVR and other operations, the requirement on blood pressure measurement accuracy is high. The device can be used for objectively and accurately monitoring the pressure of the radial artery, the pressure of the aorta, the pressure of the coronary artery and the pressure change of the left ventricle, and has important significance for guiding the progress of the operation and reducing the complications. Clinically, different patients have different heart horizontal positions, and the height of the existing pressure sensor fixing device is not easy to adjust and is fussy to fix. Therefore, a need exists for a method for measuring blood pressure more accurately and conveniently in the operation process, which has positive significance for guaranteeing the treatment effect of patients.
