Trio™ Operating Instructions 0070-10-0666-01 ix
Precautions Introduction
CAUTION: A patient's skin is sometimes fragile (i.e. on pediatric and 
geriatric patients or due to physiological conditions). In 
these cases, a longer time duration between measurements 
should be considered to decrease the number of cuff 
inflations over a period of time. In extreme cases, a thin 
layer of soft roll or cotton padding may be applied to the 
limb in order to cushion the skin when the cuff is inflated. 
This measure may affect NIBP performance and should be 
used with caution.
CAUTION: Observe caution on all patients (Pediatrics and Adults) when 
NIBP is set to the Continuous mode and the 1 minute 
Interval. When the NIBP “Continuous” interval is chosen, the 
Trio will continually take back to back blood pressure 
readings. As a safety precaution, a limit is placed on the 
Continuous mode to revert to an interval of every 5 minutes 
after 5 minutes of continuous readings.
CAUTION: Any condition which may affect the regularity and strength 
of arterial pressures (such as patient movement, cardiac 
arrhythmias, restriction of hose, etc.), will affect the 
accuracy and ability to measure the NIBP. 
CAUTION: When cleaning sensors, do not use an excessive amount of 
liquid. Wipe the sensor surface with a soft cloth, dampened 
with a cleaning solution.
CAUTION: Do not subject the sensor to autoclaving.
CAUTION: Do not use sensors or cables that are damaged or have 
deteriorated.
CAUTION: Replace the battery with one of the following part numbers: 
0146-00-0043 (for a sealed lead acid battery),
0146-00-0069 (for a Lithium Ion battery).
CAUTION: Remove the battery if the Trio is not likely to be used for an 
extended period of time.
CAUTION: Remove the battery prior to shipping the Trio.
CAUTION: To avoid permanent damage, do not expose metal 
components (pins, sockets, snaps) to disinfectants, soaps or 
chemicals.
CAUTION: The cuff must be properly applied to the patient's limb 
before inflating. If it is inflated without being securely 
wrapped, damage to the cuff can result.
CAUTION: Only connect NIBP Luer fittings to Blood Pressure Cuff or 
Monitor.
CAUTION: During the decontamination process, do not get the LpH SE 
Germicidal detergent into any vent openings.
CAUTION: To ensure continued use of the Factory Defaults when the 
unit is powered off and on, save the Factory Defaults as the 
User Default Configuration (see section 3.1.2).
