Attaching the Sensor to the Patient
To attach the sensor to the patient:
Choose the appropriate sensor. See sensor table for additional information. 1.
If using a reusable sensor, clean or disinfect the sensor per 2. Cleaning or Disinfecting the Sensors
section in this chapter. (
7
Disposable sensors are for single-patient use and do not require
cleaning or disinfecting.)
Check the sensor and oximetry cable for damage and integrity. See 3. Checking the Sensor and
Oximetry Cable section for additional information.
Attach sensor to the patient. 4.
WARNING! Prolonged use or the patient’s condition may require changing the sensor site
periodically. Change sensor site and check skin integrity, circulatory status, and
correct alignment at least every 4 hours.
WARNING! When attaching sensors with Microfoam
®
tape, do not stretch the tape or
attach the tape too tightly. Tape applied too tightly may cause inaccurate
readings and blisters on the patient’s skin (lack of skin respiration, not heat,
causes the blisters).
WARNING! SpO
2
measurements may be adversely affected in the presence of high ambient
light. Shield the sensor area (with a surgical towel, for example) if necessary.
WARNING! Dyes introduced into the bloodstream, such as methylene blue, indocyanine
green, indigo carmine, patent blue V (PBV), and fluorescein, may adversely
affect the accuracy of the SpO
2
reading.
WARNING! Optical cross-talk can occur when two or more sensors are placed in close
proximity. It can be eliminated by covering each site with an opaque material.
WARNING! Remove fingernail polish or false fingernails before applying SpO
2
sensors.
Fingernail polish or false fingernails may cause inaccurate SpO
2
readings.
WARNING! Significant levels of dysfunctional hemoglobins, such as carboxyhemoglobin
(with CO-poisoning) or methemoglobin (with sulfonamide therapy), will affect
the accuracy of the SpO
2
measurement.
WARNING! Tissue damage may result from overexposure to sensor light during
photodynamic therapy with agents such as verteporphin, porfimer sodium,
and metatetrahydroxyphenylchlorin (mTHPC). Change the sensor site at least
every hour and observe for signs of tissue damage. More frequent sensor site
changes/inspections may be indicated depending upon the photodynamic
agent used, agent dose, skin condition, total exposure time or other factors.
Use multiple sensor sites.
