Correlation of Arterial Blood Gas (ABG) and Venous Blood Gas (VBG) in the Undifferentiated Critically Ill Patient

Not Applicable

Completed

• Conditions: Patients Needing Blood Gases
• Interventions: Other: Venous Blood Gas

• Registration Number: NCT01287884
• Lead Sponsor: Christiana Care Health Services

Brief Summary

The primary objective of this study is to identify a correlation between the pH and pCO2 in arterial and venous blood. The secondary objectives include a correlation of pulse oximetry and arterial pO2 along with subgroup analyses of specific patient populations such as congestive heart failure, chronic obstructive pulmonary disease, diabetic ketoacidosis, pneumonia, overdose, and trauma.
