Evaluation of a new instrument offeringsodium, potassium, and ionized calcium incombination with haematocrit, pH and bloodgas analysis; the performance of the NovaStat Profile 1

摘要

The Nova Stat Profile 1 analyser, a combined sodium, potassium,ionized calcium, haematocrit and conventional blood gas analyser,was evaluated over a four month period. In addition to assessingand demonstrating that the instrument met analytical requirements,an appreciation of the use of ionised calcium (iCa) was made.Prospective costs were characterised and practical problems of iCameasurement addressed.
