Summary

The purpose of this study is to examine the agreement between venous blood gas and arterial blood gas measurements in patients in the Intensive Care Unit.

Detailed description

Venous blood gas analysis may be an alternative to arterial blood gas analysis for acid-base status, reducing the need for frequent invasive arterial sampling. The objective of this study is to examine the agreement between ABG and VBG samples for all commonly used parameters (pH, pCO2 and bicarbonate) in a pathologically diverse ICU patient population, specifically analyzing multiple paired arterial and venous samples from each patient.

Conditions

• Acid-Base Balance

Interventions

Type	Name	Description
PROCEDURE	Venous blood gas analysis	When an ABG is deemed to be necessary as part of ICU management, a central venous sample will also be obtained with minimum delay (always \< 2 minutes) between the samples. The samples will be analyzed by a blood gas analyzer as quickly as possible.
