Why do we need invasive blood pressure monitoring?

Blood pressure refers to the lateral pressure in blood in a blood vessel against a unit area of the blood vessel wall. The method of measuring blood pressure can be divided into non-invasive monitoring and invasive monitoring, among which non-invasive detection is indirect pressure measurement, which is relatively easy to grasp and has a wide range of indications. But the drawback is obvious: it is not accurate enough, it can only test blood pressure at a point in time.

In invasive monitoring, the catheter is directly connected to the blood vessel and directly touches the blood, the pressure in the blood vessel is converted into an electrical signal by the pressure sensor to be recorded in the monitor, and then the monitor is converted into numbers and waveform. Invasive monitoring can provide continuous and accurate systolic blood pressure, diastolic blood pressure and average blood pressure, draw the arterial pressure curve, find the change of blood pressure at any time, and can conveniently take blood for blood gas analysis, so as to relieve the pain of patients.

Which patients need invasive blood pressure monitoring? When blood pressure must be kept within a narrow range, critically ill patients whose blood pressure may fluctuate greatly and rapidly need to be observed in real time, and patients whose blood pressure cannot be monitored without invasiveness and need to repeatedly take arterial blood samples for blood gas analysis. Departments used: operating room, anesthesiology department, ICU, emergency department, PCI surgery for coronary heart disease treatment (interventional department, cardiology department, catheterization laboratory).
