Emergency Departments

Application of v-TACTM software in the emergency department (ED) presents several benefits over the use of arterial blood gas (ABG), venous blood gas (VBG) or capillary blood gas (CBG) alone.

EDs already using VBG as the main screening tool

In recent years, VBG has become more and more popular as an initial screening tool in the ED. However, v-TACTM can compensate for most of the limitations and represents a substantial improvement over the use of VBG alone.

Summary of benefits over the use of VBG alone:

  • Reduces unnecessary follow-up examinations and speeds up time-to-care: For patients with, for example acid-base disturbances, additional examinations following a VBG may be needed. such as an ABG. Application of v-TACTM will reduce the need for follow-up ABG (eliminating this work process) and speed up the time-to-care
  • Estimates severity of acidosis/alkalosis: v-TACTM will automatically provide an estimate of the severity of acidosis/alkalosis without the need for a follow-up ABG
  • Reduces ‘false positive’ hypercarbia: When using VBG alone, a number of patients will fall into hypercarbia due to pvCO2 > 45 mmHg (6 kPa). v-TACTM will eliminate ‘false positive’ hypercarbia patients
  • Discovers marginal hypoxemia: v-TACTM will discover marginal hypoxemia
  • Gets ABG baseline on admission: v-TACTM will provide a baseline for blood gas values at the time of patient admission and hence as a reference during the hospital stay
  • Prevents misinterpretations of VBG measurements: Un-experienced medical doctors may accidently misinterpret VBG values. Using v-TACTM arterialised values will allow the clinical staff to use standard ABG interpretation tools and techniques

Application of v-TACTM in EDs already using VBG is straight-forward: all you need is to measure the corresponding SpO2 value and enter the result on the blood gas instrument. The calculated ABG values are automatically and instantly available.

EDs currently using arterial blood gas by puncture

For emergency departments using arterial blood gas for screening, the application of v-TACTM creates instant advantages, including:

  • Enables systematic screening and faster results: A blood sample for VBG is easily taken in combination with other regular blood samples using a venous line.
  • Reduces the need for ABG: Systematic screening by VBG and v-TACTM significantly reduces the need for ABG by arterial puncture
  • Reduces patient pain and discomfort: It is generally accepted that arterial puncture is a painful and unpleasant experience for the patients and should be minimised.
