Question 1

where's the pulmonary artery is located at?

Accepted Answer

Off the right heart: It is the main artery coming of the right ventricle/heart. It goes to both lungs carrying blood with low oxygen.

Question 2

what is the normal diameter for a pulmonary artery?

Accepted Answer

25mm: 25mm is upper limit of normal.

Question 3

what's a pulmonary artery catheter used for?

Accepted Answer

Measures pressure: Pa catheter is used in the ICU for precise hemodynamic management of critical patients.  When used properly, it can be a life saving tool.

Question 4

how does pulmonary artery differ from the vena cava?

Accepted Answer

Anatomy lesson: The pulmonary artery is the vessel that carries blood from the right ventricle to the lungs where the blood is oxygenated. The vena cava are veins that drain blood into the right atrium from both the upper and lower halves of the body.

Question 5

is it dangerous to have an enlarged pulmonary artery?

Accepted Answer

May be a sign of...: An enlarged pulmonary artery may indicate pulmonary arterial hyper tension. A work up should be done to investigate. A 2d-echo, ct scan, possible sleep study....

Question 6

what does this mean other anomalies of pulmonary artery and pulmonary circulation with collateral flow?

Accepted Answer

Partial description: That sounds like only part of a larger description? Anomalies usually refers to a congenital or birth defect. Collateral flow means blood is reaching its target tissue by alternate routes. Taken all together, my guess is: there is some congenital obstruction or diversion of blood from the right ventricle thru the lungs that, nonetheless, has found a way to get through.

Question 7

please explain why pda does not occur in right branch of pulmonary artery?

Accepted Answer

Pda: if there is a right sided aortic arch, there could be a PDA to the right pa branch, this would require several simultaneous congenital malformations which would have a very low probability.

Question 8

can a pulmonary artery rupture be fatal?

Accepted Answer

Rupture PA fatal: The pulmonary artery is large, with pressure lower than systemic pressure. So, yes a rupture, tear, of laceration in the pulmonary artery (or one of its many branches) can be lethal; blood loss, not easy to control, or compress.

Question 9

how does one know if one has a ruptured pulmonary artery?

Accepted Answer

One is dead: A ruptured pa is one of the fastest ways to die.  I wouldn't worry about it.  If you're coughing up blood, and it's not from a nosebleed, that's a medical urgency if not emergency, but it's probably not a pa rupture.

Question 10

how to differentiate between a central line and a pulmonary artery catheter?

Accepted Answer

Length : CVP catheter can  not go beyond the right atrium and therefore it is less than 50 cm long.In contrast pulmonary artery catheter can go past the pulmonary artery and into the pulmonary capillaries and it is over 100cm long. In addition it has a balloon tip to facilitate the positioning of the catheter into the pulmonary artery via a peripheral vein.
