Bedside blood gas testing can be performed in real time in different departments throughout the hospital and the results are available immediately. Other routine samples are sent to a central laboratory for testing. arterial blood gas analysis In the case of the Siemens blood gas analyzer, the central laboratory uses the Rapid Point 500, the Pukett meter and the Rapid Lab 1200 blood gas analysis system.

Hospitals can set up rapid point 500 systems in clinical departments such as icu or picu, and blood gas analysis must be uniform in administration or comparable in measurement of instrument results. Regardless of the type of blood gas analyzer measured, it should ensure that clinicians receive consistent test results and make the same clinical decisions for patients.

"Because of the variation in measurements across instruments, laboratory measurement systems can mislead physicians and give the wrong treatment plan when they give different results for the same sample." To effectively promote comparability of results between instruments, AACC expert Malone pointed out that different instrument manufacturers work together to find different ways to address the consistency of measurement results for the same specimen. This also means that comparability of measurements between methods can be achieved.

To demonstrate the comparability of results between the Pukett instrument and the central laboratory blood gas system. First, we collected heparin, anticoagulant, and fresh blood. The bioelectrode method was used to perform ph and gas measurements over a period of time, and the samples were corrected for other analytes by adding different solutions to cover the measurement range of each test. Air bubbles were removed after collection or prior to analysis following appropriate sample handling procedures.

Samples were analyzed in normal arterial mode within 10 minutes using two Rapid Point 500 and Rapid Lab 1265 analyzers. All analyzers were quality controlled daily and run regularly according to an automated quality control program (aqc). Comparative studies were performed using clsi ep09-a3 methodology on patient samples to compare measurement procedures and estimate bias. The statistics, including slope (m), intercept (b) and determinant (r2), were calculated by ordinary or weighted regression analysis of the following analytes
