2048723-002C CARESCAPE V100 Vital Signs Monitor 2-13
Equipment overview: Overall principles of operation
Monitors with auscultatory reference (DINAMAP auscultatory
reference technology)
In these monitors, the reference blood pressure is the auscultatory method for
adult and pediatric populations. For neonatal populations, the usual reference is
the invasive blood pressure obtained from the umbilical artery.
NOTE
For neonatal determinations the SuperSTAT algorithm is always used.
Temperature
The monitor uses the following technologies to measure patient temperature:
Alaris Turbo Temp, Alaris Tri-Site, or Exergen.
Alaris temperatures
The Alaris temperature probes contain a heating element that preheats the
probe to reduce determination time. The heating function is controlled by the
Main Board. The Alaris probes also contain a thermistor that indicates the
temperature. When the probe is attached to the temperature connector and
patient, the signal generated by a thermistor that senses temperature is routed
to the Main Board. When the probe makes contact with the patient, the
resistance of the thermistor is sensed by circuitry on the Main Board. The Main
Board then processes the digital signal and displays the patient temperature on
the UI Board and printer in Celsius or Fahrenheit.
When the monitor is powered on, the monitor automatically calibrates the
temperature circuit to account for ambient room temperature. This is done by
measuring a high precision resistor of known value, computing a calibration
factor, and applying this factor to all subsequent measurements.
NOTE
If large changes occur in the ambient temperature, the temperature system
can be recalibrated by cycling power using the
On/Off button.
Furthermore, at one minute intervals, the monitor verifies the voltage supplied to
the temperature circuit to ensure that readings calculated using that factor are
accurate. If the voltage is found to be out of tolerance, the monitor issues an
alarm.
Alaris Turbo Temp or Tri-Site temperature options
NOTE
Either the Turbo Temp or the Tri-Site temperature option can be enabled on
the monitor at a time.
The Alaris temperature technology supports two temperature options: Turbo
Temp or Tri-Site. The Turbo Temp and Tri-Site temperature options allow the
clinician to take oral, rectal, or axillary temperature readings.
The Turbo Temp or Tri-Site temperature options support two different
temperature measurement modes of operation: fast (predictive) or continuous
(monitor).

The Turbo Temp temperature option can take a fast (predictive) oral or rectal
