Venous (Peripheral) Oxygen Saturation
Label Mnemonic: VOSP
Epic Lab Code: LAB8592
Downtime Form: A-1a Critical Care/Special Care Nurseries Laboratory Requisition
Critical Care - Relocated to Core Laboratory
6240 RCP
356-3527
Specimen(s):
Whole Blood (syringe only)
Collection Medium:
Lithium/Sodium Heparin syringe
Minimum:
0.5 mL in Lithium/Sodium Heparin syringes ONLY. No air bubbles in syringe.
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 peripheral site (e.g., standard venipuncture) as opposed to central catheter such as PICC line or pulmonary artery catheter. 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.

This test is also performed in the Iowa River Landing (IRL) clinical laboratory (for specimens drawn at that site).
Methodology:
Oximetric
