Brief Summary:

The study is about comparing blood samples obtained from the superior vena cava and the pulmonary artery. The investigators will compare the values of PCO2 and PO2 from these two sites, in order to see if exists a PCO2 gap and a PO2 gap, different from zero. Moreover the investigators want to find out if these gaps are related with changes in the cardiac output, the hematocrit or if they can predict post operative dysfunctions.

Blood samples will be taken at six different times as scheduled by the protocol. Along with the two venous blood samples, an arterial blood sample will be taken too, from a radial of femoral artery catheter.

Official Title: Evaluation of PCO2 and PO2 Values in the Pulmonary Artery and in the Superior Vena Cava: Relationship With Cardiac Output, Hematocrit and Post Operative Organ Dysfunction
Actual Study Start Date : July 19, 2018
Actual Primary Completion Date : July 23, 2019
Actual Study Completion Date : July 24, 2019

Intervention Details:
  • Other: blood samples
    blood samples will be obtained from the superior vena cava (via centra venous catheter), from the pulmonary artery (via Swan Ganz catheter), and from a radial or femoral artery catheter


Primary Outcome Measures :
  1. PCO2 gap changes [ Time Frame: two days ]
    See if exists a PCO2 pa-svc gap different from zero in patients undergoing cardiac surgery

  2. PO2 gap changes [ Time Frame: two days ]
    See if exists a PCO2 pa-svc gap different from zero in patients undergoing cardiac surgery
