Q

What West lung zone is considered ideal for placement of a PAC? why?

A

it should be placed in an area within West lung zone III BC the PAP is greater than the pulmonary venous pressure which is in turn greater than the alveolar pressure in this position

Q

What measurements can a pulmonary artery catheter make indirectly?

A
  • left ventricular filling pressure, right-sided cardiac output
    Measurements such as PVR and SVR are calculations made on data observed directly and indirectly.
    -PAOP estimates the LV end-diastolic pressure (preload).
  • PCWP is the LV equivalent of the CVP for the right ventricle.

Q

When inserting a pulmonary artery catheter via the right internal jugular vein, what are the distances the catheter must travel to reach the cardiac and pulmonary structures?

A

Right atrium: 15-25 cm,

right ventricle: 25-35 cm, pulmonary artery: 35-45 cm, pulmonary artery wedge position: 40-50 cm

Q

What conditions would make monitoring core body temperature via a pulmonary artery catheter inaccurate?

A

Thoracotomy and cardiopulmonary bypass can render pulmonary artery temperatures unreliable.
