Improve your mixing with the safePICO arterial blood gas syringe

  • The safePICO 1.0 mL aspirator label clearly shows the amount of blood you need for correct automatic mixing on most ABL analyzers

  • Built-in gold-coated mixing ball helps you obtain a homogeneous sample

  • safeTIPCAP minimizes the risk of blood contact

  • Barcode helps you get a correct match between your patient and blood sample

  • Integrated needle shield minimizes the risk of needlestick injury

  • Dry electrolyte-balanced heparin reduces the risk of your sample clotting

Why mixing is important in the preanalytical phase

In a Radiometer-sponsored webinar on minimizing preanalytical errors in blood gas testing, 48% of participants mentioned issues related to mixing as the most prevalent errors in the preanalytical phase of blood gas testing. Examples of such errors in mixing are clots or hemolysis

The safePICO syringe is designed to help you mix your sample. That’s why it comes with a built-in mixing ball and dry electrolyte-balanced heparin, it aims to support you in getting a clot-free, homogeneous sample.

The safePICO syringe helps minimize other preanalytical errors, such as: 

Manual mixing and automatic mixing

The built-in mixing ball in the safePICO syringe aids in the manual mixing of the sample.

However, when you mix your sample manually, make sure you don’t mix it too vigorously to reduce the risk of hemolysis. [1]

Using automatic mixing integrated in your blood gas analyzer aids in obtaining a homogenous sample. [2]

In fact, studies comparing manual and automatic mixing have demonstrated that automatic mixing is superior to manual mixing in producing a homogeneous sample and obtaining correct results. [2]

The safePICO aspirator for arterial line blood gas sampling

The safePICO aspirator has an integrated mixing ball and a new 1.0 mL label.

The label clearly shows the amount of blood you need for correct automatic mixing. It also shows you the amount you need for measuring all possible parameters on most ABL analyzers.

With the 1.0 mL label, you get support in using nothing more or less than the exact amount of blood necessary for your blood gas test. 

Thus the 1.0 mL label contributes to Patient Blood Management.

Barcode connects patient with sample

The safePICO blood gas syringe is already barcoded, helping you match the sample with the correct patient.

With the FLEXLINK data management system, you can scan the sample directly at the bedside and link it with your patient’s ID.

This gives you confidence that you have the right result for the right patient.

What we’ve done to support you as a caregiver

At Radiometer, we believe that supporting caregivers should be a top priority in all phases of acute care testing.

The integrated needle shield device on the safePICO self-fill syringe lowers the risk of needlestick injury.

Also, the vented safeTIPCAP limits the risk of blood contact while helping you expel air bubbles from the sample.

The cap seals the sample and aims to prevent contact with patient blood, even during transport and analysis.
