For testing syringe, capillary, microsyringe, and microcapillary modes, blood was
collected in heparinized vacuum tubes. It was tonometered at 37.0
C to each of
three levels to prepare samples for pH analysis, and five levels to prepare samples
for pCO
2
and pO
2
analysis. Blood was spiked/diluted to each of three levels to
prepare samples for sodium, potassium, calcium, chloride glucose and lactate
analysis. Multiple runs were made using these samples on four 860 systems, except
for lactate. For lactate, multiple runs were made on six 860 systems. The
experimental protocol called for three replicates of each level in each run.
For testing the expired gas mode, 10 mL of tonometry gas were drawn into a
12 mL syringe and aspirated into the 860 system for analysis. Multiple runs were
made using five levels of expired gas on four 860 systems. The protocol called for
three replicates of each level in each run.
Table E-31 through Table E-44 summarize the results of the 860 system whole
blood, expired gas, and electrolyte recovery and precision testing.
