Introduction Precautions

viii 0070-10-0666-01 Trio™ Operating Instructions

CAUTION: Inaccurate SpO

measurements may be caused by:

• incorrect sensor application or use

• significant levels of dysfunctional hemoglobins, (e.g.,

carboxyhemoglobin or methemoglobin)

• intra-vascular dyes such as indocyanine green or

methylene blue

• exposure to excessive illumination such as surgical

lamps (especially ones with a xenon light source),

bilirubin lamps, fluorescent lights, infrared heating

lamps, or excessive ambient light. In such cases, cover

the sensor site with opaque material.

• excessive patient movement

• venous pulsations

• electro-surgical interference

• placement of a sensor on an extremity that has a blood

pressure cuff, arterial catheter or intra-vascular line.

• nail polish or fungus

CAUTION: In certain situations in which perfusion and signal strength

are low, such as in patients with thick or pigmented skin,

inaccurately low SpO

readings will result. Verification of

oxygenation should be made, especially in preterm infants

and patients with chronic lung disease, before instituting

any therapy or intervention.

CAUTION: Many patients suffer from poor peripheral perfusion due to

hypothermia, hypovolemia, severe vasoconstriction,

reduced cardiac output, etc. These symptoms may cause a

loss in vital sign readings.

CAUTION: If the sensor or patient cable are damaged in any way,

discontinue use immediately. To prevent damage, do not

soak or immerse the sensor in any liquid solution. Do not

attempt to sterilize.

CAUTION: When equipped with Masimo SpO

, use only Masimo

oxygen sensors and cables. Use of other oxygen sensors

may cause improper oximeter performance.

CAUTION: When equipped with Nellcor SpO

, use only Nellcor oxygen

sensors and cables. Use of other oxygen sensors may cause

improper oximeter performance.

CAUTION: When using the Trio equipped with SpO

, use only

approved supplied oxygen transducers and Patient Cables.

Use of other oxygen transducers may cause improper

oximeter performance.

CAUTION: Use only approved blood pressure cuffs and hoses with the

Trio.

CAUTION: Please consult a physician for interpretation of blood

pressure measurements.

CAUTION: A blood pressure measurement can be affected by the

position of the patient, and his/her physiological condition

as well as other factors, such as patient movement.
