Blood Gas AnalyzersAs the status of blood gas plays a key role in the evaluation of the critically ill patients, it is crucial for the clinical labs as well as healthcare facilities to have reliable analyzers to deliver rapid and reliable results. Advanced blood gas analyzers can streamline work processes and reduce errors in clinical labs or critical care facilities.

There are several models of analyzers in the market that are suitable for measuring the basic blood gas panels as well as electrolytes and metabolites. Advanced blood gas analyzers accurately measure the level of arterial oxygen tension (pO2), carbon dioxide tension (pCO2), and acidity (pH), assisting physicians in disease diagnosis and treatment. Advanced analyzers have computer interfaces and internal algorithms to calculate pertinent parameters.

However, inappropriate sampling devices and improper handling can cause inaccuracies in blood gas analysis. Factors to be considered while choosing an analyzer includes type of analyzer (whether hand-held or benchtop), number of analytes measured, sample size, sample handling (single or multiuse cartridges), clot protection, analysis time, automation, and operating costs.

Leading manufacturers of blood gas analyzers include Roche Diagnostics, Radiometer America Inc., Medica and Siemens Healthcare Diagnostics Inc. The Medica EasyStat analyzer measures pH, PCO2, PO2, Na+, K+, Ca++, Cl-, and Hct and calculates additional parameters, patient parameters, including FIO2, patient ID, patient temperature, and %FIO2 drawing site. Its compact format and modular design significantly reduces maintenance and space requirements.

The RAPIDLab 1200 System from Siemens is designed to enhance blood gas testing efficiency in the clinical laboratory and combines testing speed and reliability with low maintenance. Laboratories can purchase new as well as recertified analyzers from established lab equipment suppliers.
