Comparison of electrolyte and glucose levels measured by a blood gas analyzer and an automated biochemistry analyzer among hospitalized patients

Performance of Gem Premier blood gas/electrolyte analyzer evaluated.

We evaluated a new analyzer designed for point-of-care testing of blood gases, sodium, potassium, ionized calcium, and hematocrit. The Gem Premier (Mallinckrodt) system has two components: the analyzer and a disposable cartridge. Analysis takes place in the cartridge, which contains the electrochemical sensors, the calibrants, the reagents, the sampling stylus, and the waste container. The syst...

Comparison of a human portable blood glucose monitor, a veterinary portable blood glucose monitor and an automated chemistry analyzer for measuring canine blood glucose concentration

Environmental testing of a blood gas/pH and electrolyte analyzer for field hospital use.

In 1983 the U.S. Army Academy of Health Sciences developed a Letter Requirement for a Blood Gas/pH Analyzer for use in Echelon 3 and 4 facilities. Field trials of several nondevelopment items and a subsequent market survey did not produce a suitable instrument. Recently, a relatively small, lightweight, and simple device became commercially available, and was tested for field applicability in a...

Comparison of blood gas and electrolyte test results from the Gem-Stat and CDI-300 versus a conventional laboratory analyzer.

Continuous blood gas monitoring devices have been an aid to the perfusionist since the introduction of the oxygen saturation meters of the early 1980s. Since that time, the perfusionist has had to decide between continuous versus intermittent sampling, and on-line (an analyzer that can automatically sample either at prescribed intervals and/or on demand) versus in-line devices (monitors that c...

Portable blood gas and electrolyte analyzer evaluated in a multiinstitutional study.

A recently introduced blood gas/electrolyte analyzer (SenDx 100((R)), renamed ABL70) intended for point-of-care, near-patient, or stat laboratory use was evaluated simultaneously in four different institutions and compared with three different laboratory bench analyzers with respect to imprecision, inaccuracy (assessed by tonometry), and patient-sample analyses. The analyzer is equipped with a ...
