v-TAC in clinical practice

It is simple to operate v-TAC in daily clinical practice. After installation of the v-TAC software the workflow is as follows

1. Draw a peripheral venous blood sample

2. Measure arterial oxygen saturation (SpO2) simultaneously with a pulse oximeter.

3. Insert the venous blood sample into the blood gas analyser and start the analysis. The exact operation of the blood gas analyser depends on the actual brand and type.

4. The v-TAC software calculates arterialised blood gas values, which instantly becomes available to the clinician on a printed report (optional) and in the electronic patient record.

The Roche cobas b 123 blood gas analysers (type 3 and 4) are among the list of blood gas analysers supported by the v-TAC software.

The workflow for Radiometer ABL equipment can be found in the v-TAC Product Description here



To operate the cobas b 123 POC system, the following steps are required:

1. Select the sample type ‘Venous’:

2. Select ‘Remark 1’ field:

3. Enter the measured arterial saturation (SpO2) value e.g. 90% using syntax ‘SPO2=90%’:
