phlebostatic axis?

ParrotHeadRN · Aug 5, 2006

If you type phlebostatic axis into google or yahoo, you will come up w/ tons of answers. I just tried it and it works well.

Ill take a wild guess here and suggest that maybe he/she is asking for the location of the reference point. The junction of the fourth intercostal space and the midpoint of the anterior-posterior diameter indicates the phlebostatic axis. Exactly what is the question he/she poses to you? While looking at the entire question we can see something maybe you are not.

Awaiting your reply,

Troy

no the question was more along the lines...

what does the phlebostatic axis point to?

i said the right atrium & he said yes but, he was looking for something more specific.

Well I guess you could elaborate and say the left and right atrium as well as the pulmonary artery. Other than those 3 things, I am stumped.

Peace,

Troy

nevermind.....duh I re-read the original post.

Let me try again....

Does the instructor mean what is "level" with the phlebostatic axis? Such as if you were to hold a yard stick perpendicular to this reference point what would be at the end of the yard stick opposite the phlebostatic axis?

Or as seems to be the obvious - what anatomical structure(s) are at the phlebostatic axis?

Weird way to word that question.

Or maybe the instructor is looking for a very specific definition of what is measured using the phlebostatic axis. Like: Storm clouds point to rain.

Also, something else to think of..... what is the phlebostatic axis used for? There is a term that includes the word "point" (not reference point).

hmmm.

we came to this question when we were discussing how to zero the transducer for an a-line.

my class and i said you place the transducer 4th intercostal space, midaxillary & our instructor asked what's the signifigance of this placement..."what are you zeroing it to, what in the body is the tranducer lined up with."

i said the right atrium and all the books i've read say the right atrium but, our teacher said there's an even more specific part of the heart (maybe even part of the right atrium as he did say we are right) the p.axis lines up with.

all the major parts of the heart; valves, atria, ventricles, sa, & av nodes have been named (we're fishing) and our instructor keeps sending us away telling us to come back with another answer.

i dunno i'm stumped. if anything he said he'll tell us the answer when we graduate (2 months).

p.s. thanx for all the effort tho people.

Hey j. I'm pretty sure the answer to your question is in this thread.

And it wasn't me.

There is another possibility that I can think of. It's not necessarily a "part" of the heart, but it is in the heart.

Sorry to be so elusive, but I think you'd be stoked to figure this out on your own.

I think there's a clue in here too:

Ooo! I think I might have it! I read the thread, then googled it and think I found it in the paper at the address below:

The phlebostatic axis points to the catheter tip or opening, or the vessel/chamber pressure at the catheter tip, where it sits in the RA or vena cava (or vena cava/RA juncture).

Huh? Whaddya think? Am I totally off? Was this already said?

Peace, and hope you're doing great, as this posting is 2 years old...
