A cardiac catheterization is done in a healthy person.The blood sample withdrawn from the cathetershows 60% oxygen saturation, and the pressurerecording shows oscillations from a maximum of 26mm Hg to a minimum of 14 mm Hg. Where was thecatheter tip located?
(A) Ductus arteriosus
(B) Foramen ovale
(C) Left atrium
(D) Pulmonary artery
(E) Right atrium




  #2

Oxygen saturation and partial pressure analysis seems a little low for normal venous blood.....i don't know how wud oxygen saturation differ from right atrium to pulmonary artery in a healthy individual.

i'll go with (E) Right atrium


  #3

It is pulmonary artery due to diastolic pressure of 14 mmHg
