Factors causing
significant variances in
sensor accuracy
Presence of dysfunctional
hemoglobins (COHb,
MetHb).
Follow hospital procedure for
determining oxygenation in
these patients.
Presence of intravascular
dyes (indocyamine green,
methylene blue) in the blood
stream.
Follow hospital procedure for
determining oxygenation in
these patients.
High ambient light level. Reduce light levels near the
patient.
Electrosurgical interference. Follow hospital procedure for
determining oxygenation in
these patients.
Patient is significantly
anemic (Hb less than 5 g/dl)
or has received large
