SpO2, SpCO, and SpMet Monitoring Considerations
The quality of the SpO
2
, SpCO, and SpMet readings depends on correct sensor size and
placement, adequate blood flow through the sensor site, and limiting patient motion and sensor
exposure to ambient light. For example, with very low perfusion at the sensor site, readings may
be lower than core arterial oxygen saturation. Test methods for accuracy are available by
contacting your local Physio-Control representative.
Use the following criteria to select the appropriate pulse oximeter sensor:
• Patient size (adult, pediatric, infant) and weight
•
Patient perfusion to extremities
• Patient activity level
•
Available application sites on the patient’s body
• Sterility requirements
•
Anticipated duration of monitoring
To help ensure optimal performance:
• Use a dry and appropriately sized sensor.
•
Choose a site that is well perfused. The ring finger is preferred.
• Choose a site that least restricts patient movement, such as finger of the non-dominant hand.
•
Be sure the fleshy part of the digit completely covers the detector.
• Keep the sensor site at the same level as the patient’s heart.
•
Apply the sensor according to the Directions for Use provided with the sensor.
• Observe all warnings and cautions noted in the sensor’s Directions for Use.
Sensor Application
The preferred site for sensor application is the ring finger of the non-dominant hand. To
position the sensor:
1. Orient the sensor so the cable is on the back of the patient’s hand.
2. Place the finger in the sensor until the tip of the finger touches the "raised digit stop."
3. The hinged tabs of the sensor should open to evenly distribute the grip pressure of the
sensor along the length of the finger. Check the arrangement of the sensor to verify
correct positioning. Complete coverage of the detector window is needed to ensure
accurate data.
The sensors are sensitive to light. If excessive ambient light is present, remove or reduce
lighting, cover the sensor site with an opaque material to block the light, and check
appropriateness of sensor site. Failure to do so could result in inaccurate measurements.
