Introduction Cautions
viii 0070-10-0699-02 Accutorr V Operating Instructions
CAUTION: When equipped with DPM SpO
2
, use only DPM oxygen 
sensors and cables. Use of other oxygen sensors may cause 
improper oximeter performance.
CAUTION: Excessive ambient light may cause inaccurate SpO
2
 
measurements. Cover the sensor with opaque materials.
CAUTION: Inaccurate readings may be caused by incorrect sensor 
application or use; significant levels of dysfunctional 
hemoglobins (i.e. carbohemoglobins or methemoglobin); or 
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 direct 
sunlight; excessive patient movement; venous pulsations; 
electro-surgical interference; and placement of a sensor on 
an extremity that has a blood pressure cuff, arterial 
catheter, or intra-vascular line.
CAUTION: Route cables neatly. Ensure cables, hoses, and wires are 
kept away from patient’s neck to avoid strangulation. Keep 
floors and walkways free of cables to reduce risk to 
hospital personnel, patients, and visitors. If the sensor or 
patient cable is damaged in any way, discontinue use 
immediately. 
CAUTION: When cleaning sensors, do not use excessive amounts of 
liquid. Wipe the sensor surface with a soft cloth, dampened 
with the cleaning solution. To prevent damage, do not soak 
or immerse the sensor in any liquid solution. DO NOT 
ATTEMPT TO STERILIZE.
CAUTION: Prolonged and continuous monitoring may increase the risk 
of skin erosion and pressure necrosis at the site of the 
sensor. Check the SpO
2
 sensor site frequently to ensure 
proper positioning, alignment, and skin integrity at least 
every eight (8) hours; with the Adult and Pediatric re-usable 
finger sensor, check every four (4) hours; for neonates and 
patients of poor perfusion or with skin sensitive to light, 
check every 2 - 3 hours; more frequent examinations may 
be required for different patients. Change the sensor site if 
signs of circulatory compromise occur. Ensure proper 
adhesion, skin integrity, and proper alignment. Exercise 
extreme caution with poorly perfused patients. When 
sensors are not frequently monitored, skin erosion and 
pressure necrosis can occur. Assess the site every two (2) 
hours with poorly perfused patients and neonates.
CAUTION: Recharge the Lithium ion battery while in the unit at room 
temperature. If using the Accutorr V in a hot environment, 
the Lithium ion battery may not charge when the unit is 
connected to the AC mains.
CAUTION: Remove the battery if the Accutorr V is not likely to be used 
for an extended period of time.
CAUTION: The Communications Connectors on the Accutorr V are only 
for use with IEC 60601-1-1 compliant equipment.
CAUTION: Never place fluids on top of this monitor. If fluid spills on the 
unit, wipe clean immediately and refer the unit to qualified 
service personnel.
