Primary Outcome Measures:

Agreement between venous and arterial blood gas measurements of pH, pCO2 and bicarbonate [ Time Frame: Duration of Intensive Care Unit Admission ] [ Designated as safety issue: No ]

Enrollment:	40
Study Start Date:	January 2008
Study Completion Date:	July 2008
Primary Completion Date:	July 2008 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1	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.

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.
