[Retracted] To Explore the Haemostatic Effect of Compression Haemostasis Using an Ultrasonic Probe under the Guidance of Ultrasound after Radial Artery Puncture

Figure 6

Before pressing haemostasis, the short axis of the ultrasonic probe is perpendicular to the arterial puncture needle into the vascular port. After pulling out the catheter, use the ultrasonic probe to press haemostasis with the force that does not show arterial blood flow overflow on the ultrasonic display screen.
