Best Practices Checklist for SpCO Comparisons
1. Ensure SpCO device is powered on and connected to computer with automatic
data capture.
2. After venous blood draw, SpCO testing must be initiated within 30 seconds
(COHb can change rapidly).
3. Sensor site selection:
  Remove anything from patient's arm that can impede blood flow to the
sensor site, such as restrictive garments, accessories, purses, backpacks,
watches, jewelry, and blood pressure cuff.
  Do not use sites with any of the following conditions:
  An anatomically abnormal finger (e.g. damaged, clubbed, deviated,
etc.).
  A finger or arm that has experienced previous surgical procedures.
  A finger or arm that is currently receiving an IV infusion.
  A finger or arm that currently used for blood pressure cuff.
  Site should be cleaned of debris and dry prior to testing.
  Nail polish should be removed prior to testing.
  Select the patient’s testing finger in the following priority.
 Non-dominant ring or middle finger.
 Dominant ring or middle finger.
4. Sensor selection:
  Use the appropriate sensor as defined in the sensor directions for use.
5. Ensure proper sensor positioning:
  Rest patient’s hand and arm with sensor on a horizontal surface securely
to limit the movement of the patient.
  Examine the finger while placed in the sensors to ensure the emitter and
detector are directly aligned on top of each other and there is no gap
between the sensor and fingertip.
  Align upper and lower red lines.
  If using a reusable sensor, make sure finger tip is inserted all the way and
touching the finger stop inside the sensor (allowing long finger nails to
extend beyond the finger stop).
