The maximum application time at a single site
should be less than 30 minutes, in order to
ensure correct sensor alignment and skin integ-

tional hemoglobin (such as carboxyhemoglobin or
methemoglobin).
 Intravascular dyes such as indocyanine green or meth-
ylene blue have been injected into the patient.
 Used in the presence of high ambient light (e.g. direct
sunlight). Shield the sensor area with a surgical towel if
necessary.
 There is excessive patient movement.
 The patient experiences venous pulsations.
 The patient has hypotension, severe vasoconstriction,
severe anemia, or hypothermia.
