Randomized Controlled Trial
Effects of syringe material, sample storage time, and temperature on blood gases and oxygen saturation in arterialized human blood samples.
The practice of on-ice storage of arterial-blood samples in plastic syringes for delayed analysis continues, and the effects of storage time and temperature on the measurement of blood-oxygen-saturation values (S(aO2)) have not been adequately described. ⋯ For accurate arterial-blood-gas results, samples drawn in plastic syringes should be analyzed immediately. If the analysis is going to be delayed, the samples should be drawn and stored in glass.
