reduce delays in cardiology services with patient-side testing

Delays can impact patient outcomes, so efficient testing processes are paramount to help maximize surgical outcomes. POC testing with the i-STAT System can help support the unit’s goal of expeditious care and allow surgeons to respond immediately to unstable patient conditions. In addition, the technology may streamline the blood analysis process (to potentially reduce equipment maintenance) and minimize changes in surgery schedules.

CVOR

KEY i-STAT CARTRIDGES

Because of the delicate nature of surgery, real-time test results are often critical, yet results from the central lab can take 60 minutes or more.1 Costly challenges, such as surgical cancellations, can add up, while the sharing of bench-top systems for blood gas analysis among a number of operating rooms can can cause delays due to the nurse having to leave the room, the system already being in use or frequent calibration requirements. The variables can potentially increase staffing requirements and impact patient care. Analysis via bench-tops (where the operating room assistant must leave the room to perform tests) can be costly, as well as potentially increase staffing requirements and impact patient care.

CATH LAB

KEY i‑STAT CARTRIDGES

In the Cath Lab, it’s important that both activated clotting time (ACT) and blood gas results are readily available.

The i-STAT System test menu enables Cath Labs to function with a single platform, helping to reduce costs while increasing operational efficiencies.

act represents the time required for a clot to form in the presence of an activator: celite or kaolin

there are two methods to measure act:

  • mechanical systems detecting blood viscosity (fibrin clot); and
  • non-mechanical systems that detect the presence of thrombin-clot through chemical assessment.

i‑STAT NON-MECHANICAL TEST

KEY ADVANTAGES
  • Earlier marker (thrombin) associated with more consistent results across duplicate ACT tests2 
  • Less susceptible to factors that affect a final physical clot3
  • Automation minimizes manual intervention and associated risks
  • Only cartridge-based ACT that can measure the entire heparin range (0-6 units/ml) with a single test. No need for high and low range ACT tests

TRADITIONAL MECHANICAL TEST

KEY DISADVANTAGES
  • Vulnerable to temperature, dilution, hematocrit, fibrinogen levels, and user technique3
  • User intervention reduces reproducibility
  • Larger sample volume in some systems limits usability for pediatric cases, impacting patient care
