Comments:

Blood gas analyses and calculations assume a patient temperature of 37°C unless the laboratory is informed of a different temperature either by phone or by paper documentation if sample is hand- delivered. Any air drawn in with the sample must be expelled immediately. Samples that contain greater than 25% air to sample volume ratio will not be analyzed. All needles must be removed from the syringe before delivery.

Methodology:

Traditional Electrodes
