→ What You can Learn from Gravity Injection - Must Read


No this post is not about drinking games or parties, it is actually about embalming. However, it seems within the funeral industry the college kids and hardcore adults might know more about it than some embalmers do today. Can anyone guess what the pressure of the alcohol is in this video, or better yet what about the rate of flow?

If you were conducting yourself within the industry with a license and have not heard someone say, "rate of flow swells the body while embalming" that would surprise me. Sure, turning the rate of flow valve to much or too quickly can lead to swelling rather quickly. Performing this action does in fact increase the measurable flowing pressure, then the internal pressure, and the result is swelling.
In regards to swelling, consider this example. If the rate of flow is equal to the rate of drainage, how can there be swelling? Better question, what is the pressure? No we aren't going to talk shell embalming or that increasing drainage is not possible even though it is- Siphonbalm. Simple answer is there can't be and so it must not be true. After just a little consideration one cannot make the rate of flow swelling claim reasonably or intelligently. The constant in the swelling occurrence is the increase in internal pressure, which can be measured with our Frankembalm machine.

But was there even such a thing as rate of flow while embalmers were putting beer bongs, I mean funnels, in the air using gravity to inject? The answer is yes. There was a rate of flow as fluid would flow due to the force of gravity. This is still true. Without force, which we measure as pressure, you do not have flow. Said another way, pressure creates flow. It is that simple.  Consider how you or anyone would gravity inject. Mild elevation as you get started. With mild elevation you will expect and get a mild rate of flow. Fluid will take the path of least resistance and be unable to pass areas of greater resistance. The elevated height will determine what is a path of great resistance or least resistance. The speed of drainage will begin to remove pooled blood from the body, this will lessen the pressure demand to distribute fluid. As rate of drainage becomes steady, increase the elevation and the job is done. Tubing size is the same as with all embalming machines, cannula size is the same, typical elevation at ten feet high would create approximately five pounds of pressure- has this ever lead to severe swelling? Not that I have seen.

How can we use this knowledge to improve our present skills? Is there a benefit to high flowing embalming? High flow results in de-saturation of tissue. In addition to distribution benefits, Jaundice cases, edema cases or even standard cases can greatly benefit of high flow embalming. Flushing bilirubin out is key for achieving a well preserved "un-green" jaundice case. Drawing moisture into the vascular system for removal will improve preservation of edematous tissue. Finally, drawing any water from any case will delay decomposition.

To make you a bit more comfortable injecting with a 'high rate of flow' with centrifugal embalming machines, here is a quick how to which probably doesn't require you to buy anything.
Make two incisions, one at the right clavicle site other at the left bra strap site.
From the left bra strap site incise and insert forceps in the subclavian vein and left jugular vein. 
From the site at the right clavicle incise and insert forceps into the right jugular vein.
Inject south via the carotid artery with pressure setting below 1 lb.
Remember what we know about gravity feed, as fluid flows and returns drainage turn the 'rate of flow' by 1/5.
As drainage continues to increases, continue opening the valve until it is completely open.
From that point raise the pressure carefully until you have achieved the desired results, you will not be disappointed.  

Whats your pressure number?

→ Displacement - Physical Science & Embalming

Flowing fluid may travel fast or slow, it can be in large vessels or small vessels, or it can be in some vessels but not others. Due to the complexity of the vascular system, its beauty, for one, it is easier to disregard all this knowledge and continue as operated. If this information makes your head hurt as much as mine, try and remember the old phrase, “No pain no gain!”
As common hand pumps, syringes, machine pumps, and even gravity feeds are provided to the embalmer, please accept that they do not aid the embalmer very well to calculate displacement. The embalmer is left to calculate this all on his or her own, and it is done usually from memory and frame of reference. Displacement is the measure of volume over time. It is not a complicated concept for us to understand; like miles per hour, so, ounces per minute. All of the above mentioned instruments used to inject or displace fluid have a force that can be calculated. Some of the above have the ability to restrict or regulate flow as well. It should be noted that when we regulate or restrict flow, we conversely influence or affect pressure. Yet when we measure displacement, it remains constant until we adjust one of the previous two variables: pressure or flow, if available. This is why perhaps our most significant frame of reference as we embalm is not the dials, numbers, and switches, but the displacement. We can calculate this visually with our imagination, yet however well this might work for us, we can do better using a flowmeter. As we connect a flowmeter to an embalming machine, we can better understand how adjusting these variables can affect the displacement of fluid from the machine. From our machine, pump settings as “high pressure with very restricted flow” can yield a displacement value the same as “low pressure with moderate rate of flow.” So what is the difference, you might ask? Sorry to disappoint you, that is not covered yet.
To answer the question, there isn’t much of a difference in either of these examples. Both methods rely on pressurizing the arterial system slowly. The pressurized arterial system next begins to dilate the smaller vessels, and so on and so forth. It is important to move slowly at the beginning stages of embalming, for reasons best known to the vascular system itself. Factors such as time of death and refrigeration, to name a few, will lead to pooled blood throughout the arterial system. Pushing the pooled blood deeper into smaller vessels will cause distribution issues for the embalmer. The goal of the embalmer initially would be to distribute the fluid well, and next to pressurize all of the vascular pathways that have been opened. See our former chapter about why fast moving fluid will aid the embalmer in distributing fluid.
The embalmer’s ability to learn more about Physical sciences as it relates to embalming can prove as useful a tool as an aneurysm hook. Holding the vascular system in high regard and understanding how fluid will or will not move within it will aid the embalmer during challenging cases where there are multiple pressure systems being encountered, from air, to fluid within the abdomen, and everything else.
