Delivery Instructions:
Deliver to laboratory immediately after collection.
Testing Schedule:
24 hrs/day, 7 days a week, including holidays.
Turn Around Time:
10 minutes (upon receipt in laboratory)
Comments:
This order is for venous oxygen saturation for a specimen drawn from a central catheter (e.g., central venous catheter, PICC line, pulmonary artery catheter) as opposed to peripheral site (e.g., standard venipuncture). Can be ordered with blood gases (0.5 mL blood required). All needles must be removed from the syringe before delivery. Samples that contain greater than 25% air to sample volume ratio will not be analyzed.
Methodology:
Oximetric
