Pulmonary Artery (Swan Ganz) Catheter Placement

A Pulmonary Artery catheter (Swan) is a long, thin, hollow tube placed in the large veins of the
neck, upper chest, or groin. This is guided through the heart and into the large vessels of the lung
(pulmonary artery). The Pulmonary Artery catheter measures pressures in the heart and the
vessels going to the lungs.

A doctor inserts the catheter and it is connected to a monitor. The monitor displays wave forms
and numbers. The purpose of this tube is to determine how much medicine or IV fluid to give
you. In addition, the catheter is used to give IV fluids, medicine, and to take blood samples.


As with any procedure, there are risks. Some of the risks include:
ξ Pain – Patients may feel a poke as the doctor inserts the needle. Numbing medicine can
be used to lessen the pain. Once the needle is in, the pain is often mild and goes away.
ξ Collapsed lung – The lung is very close to veins in the neck and chest. When a central
catheter is placed in the chest area, if a needle passes through or misses the vein, the
needle could pierce the lung and cause it to collapse. If this happens, the doctor can
reinflate the lung by placing a chest tube. This may happen even if everything is done the
right way.
ξ Infection – Any tube entering the body can make it easier for bacteria from the skin to
get into the bloodstream. Special care in cleaning the skin and applying the dressing at
the catheter site is done to decrease the risk of infection.

Some other risks specific to the Pulmonary Artery catheter include:

ξ Altered heart rhythms– The Pulmonary Artery catheter can tickle the heart and cause
the heart to beat too fast or too slow. If this occurs, treatment is done to return the heart
to a normal beat pattern.
ξ Rupture of the pulmonary artery – Though very rare, the catheter could break the large
blood vessel in the lung. This could be life-threatening.
