A member asked:
How to differentiate between a central line and a pulmonary artery catheter?
A doctor has provided 1 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.
