Which method can be used to obtain pressure for the injection of arterial fluid?

The method of using a hand pump to obtain pressure for the injection of arterial fluid is effective due to the control it allows the embalmer over the rate and volume of fluid being injected. Hand pumps can provide a steady, consistent pressure that is necessary for the embalming process. This method is particularly valuable in managing the distribution of embalming fluid throughout the vascular system, ensuring that it reaches the desired areas effectively.

Using a hand pump also allows for adjustments to be made quickly based on the embalming situation, such as the condition of the body and the presence of any blockages in the vascular system. This direct control can be crucial when dealing with varying resistance in different body tissues.

Other methods for injecting arterial fluid, such as hydro aspirators, gravitational siphons, and electric pumps, each have their advantages and specific applications, but a hand pump is often preferred for the precision and tactile feedback it provides during the arterial injection process.
