Purchasing Blood Gas AnalyzersOne of the most important laboratory tests, analysis of arterial blood gas is performed to classify respiratory failure into subtypes. A blood gas test can reveal the severity of the respiratory failure episode by measuring the partial pressures of oxygen (PO2), carbon dioxide (PCO2) and the acidity (pH) of arterial blood.

According to experts, choosing a blood gas analyzer for a specific lab depends on much more than just the technology underlying the analyte measurements and the analyzer’s performance. In addition to a clear understanding of the tests required, factors such as analyzer size, ease of use and capital and consumable costs must be considered before making the purchase decision.

Important issues that need to be considered are:

  • the range of analytes
  • nature of quality control
  • availability of consumables
  • reliability, ease and safety
  • maintenance and troubleshooting procedures
  • computer interface to allow automatic results reporting and communication with a facility’s data management system
  • quality of training and customer support
  • cost

The level of device automation is an important factor to consider if non-lab trained personnel are expected to use the device. Automated features and data management capabilities such as recording of patient identification, test results and date and time, would come in useful. It should also be able to record quality control results, reagent lot numbers, and operator id. The ability to generate reports based on data collected is important.

There are many different brands and models of blood gas analyzers in the market. One device that is impressing with its efficacy and small footprint is Medica’s EasyBloodGas™. In addition pH, PCO2, and PO2, it calculates 11 additional parameters. It offers features such as:

  • Compact electrode design
  • Precise control of calibrator volumes
  • Digital data entry and integration of entries with patient results
  • Display and printing of measured and calculated results
  • Simple menus for easy operation
  • Small footprint for easy integration with lab workflow

All components are combined into three simple modules in this analyzer. Maintenance is simple and limited to the replacement of the reagent module, electrodes, and a single pump tube. Purchase the EasyBloodGas™ from a lab equipment supplier that ensures competitive pricing and efficient customer support service.
