Minimize the need for (repeated) arterial punctures

Arterial blood gas analysis is an important tool in assessing patient status, and in departments of pulmonary medicine. Arterial blood is typically sampled via arterial puncture. These patients, such as COPD patients, often experience repeated arterial punctures needed for, e.g. adjustment of oxygen therapy and non-invasive ventilation (NIV).

Using v-TACTM, the need for arterial punctures can be minimize or even obviated.

In situations where the patient already has a venous line (such as a vacutainer holder w/needle or butterfly), this access can be used to draw venous blood for blood gas testing, and combined with the corresponding SpO2 measurement, v-TACTM software can calculate the arterial acid-base and blood gas values.

The benefits include:

  • Save clinical resources: A v-TACTM measurement takes just a few minutes, compared to arterial or capillary blood gas measurement, which easily takes 10 minutes or more.
  • Reduce pain: Spare the patient the painful and unpleasant experience of repeated arterial punctures.
  • Reduce risk: Reduce the risk of haematoma and other potential side effects of arterial punctures.
  • Use less skilled personnel: Venous punctures can be done by less skilled personnel, compared to arterial punctures, where medical doctors or specially trained nurses are needed.
  • Get ABG results quicker: Especially during night shifts and weekends, arterial blood gas testing often requires calling in skilled personnel from a different department. It may take several minutes before such personnel become available.
