Introduction
Product Limitations
Product Limitations
Non-invasive blood pressure (NIBP) accuracy depends on the application of the proper cuff
size. See Chapter 3.0 of the Operating Instructions for detailed information.
The Accutorr V will not operate effectively on patients who are experiencing convulsions or
tremors.
The Accutorr V is a portable device intended for intra-hospital use.
If the pressure cuff is not placed at the patient’s heart level, the NIBP measurement may be
subject to error, due to the hydrostatic effect.
The pulse rate data displayed on the Accutorr V is computed from the measurement of
peripheral pulses (peripheral pulses taken only during a measurement cycle). The rate
measured by the Accutorr V may differ from the rate of an ECG monitor. This is because the
ECG is an electrical signal that may not always result in a peripheral pulse.
Administration of certain vasoconstrictor drugs (for example, norepinephrine), may reduce
peripheral perfusion to a level that prevents the Accutorr V from taking pulse rate
measurements.
Arterial compression, tricuspid regurgitation, or other conditions may reduce perfusion to a
level that prevents the Accutorr V from taking pulse rate measurements.
The presence of arrhythmias may increase the time required to complete a measurement and
may extend this time so that a measurement cannot complete.
The Accutorr V is not intended for use during CPR. The monitor uses an oscillometric
technique based on normal peripheral circulation to compute blood pressure.

Specifications
Introduction
The Accutorr V monitors patient vital signs (including non-invasive blood pressure (NIBP),
pulse oxygen saturation (SpO2), and pulse rate (PR)) for a single adult, pediatric, or neonatal
patient. It also monitors oral or rectal mode temperature (Temp) for a single adult or pediatric
patient; or axillary mode temperature for a single neonate, adult, or pediatric patient using
the optional Temperature Module.
2.2
NIBP Measurement
The NIBP module is used to measure the systolic pressure, diastolic pressure, and mean
pressure in the neonatal, pediatric, and adult modes. The Accutorr V calculates NIBP values
using the oscillometric method of noninvasive blood pressure measurement. These
measurements correspond to comparisons with auscultatory values, measured using the fifth
Korotkoff sound within ANSI/AAMI SP10 standards for accuracy.

NIBP Measurement Cycle
2.3
Specifications
NIBP Measurement Cycle
There are two different modes of measurement operation: manual and interval modes. The
manual mode requires the operator to initiate the measurement cycle.
The interval mode follows a configured plan of automatically initiated measurement cycles,
using the follow selections:
OFF (manual), STAT, or 1, 2, 3, 5, 10, 15, 20, 30, 60, 120, 240 minutes
NOTE:
When the NIBP STAT interval is selected, the Accutorr V
takes back to back (one right after the other) blood pressure
readings. As a safety precaution, there is a five minute or
10 measurement limit for continuous NIBP measurements.
After 5 minutes or 10 measurements, the NIBP module
automatically switches to the mode in use before NIBP STAT
was selected. This reduces the chance of surface vessel
rupture (petechia).
The maximum adult and pediatric measurement cycle is 180 seconds.
The maximum neonatal measurement cycle is 90 seconds.
The NIBP module adjusts the inflation pressure automatically according to the systolic
pressure of the last measurement. If the first measurement is unsuccessful, the subsequent
inflation pressures change to 50 mmHg higher than the previous systolic pressure in adult or
pediatric mode, and 40 mmHg higher than the previous systolic pressure in neonate mode.
(The subsequent inflation pressure should be greater than the systolic pressure in the previous
measurement).
2.3.1
Cuff Inflation Time
If the cuff pressure does not attain 15 mmHg within 20 seconds for adult and pediatric
patients, or 15 mmHg within 10 seconds for neonate patients from the start of inflation, the
Accutorr V retries measuring up to three times. If the target pressure is not reached after three
retries, the cuff is deflated, and a status code displays.
2.3.1.1
Cuff Pressure Automatic Check Algorithm
If the monitor cannot inflate the cuff to the Pressure Threshold within the expected time period,
the monitor deflates the cuff, cancels the measurement, shuts off the pump, and displays the
message “Unable to Measure”. The cancellation occurs based on the following tables.

When sensors are used on neonatal subjects as recommended, the specified accuracy range
increases by ± 1 digit, to account for the theoretical effect on oximeter measurements of fetal
hemoglobin in neonatal blood.
Neonatal accuracy specifications are based upon testing neonatal sensors on healthy adult volunteers in induced hypoxia studies, in the range of 70-100% SpO2. The specified accuracy also takes
into account published literature which predicts that there may be a small difference in % SpO2
reported by the oximeter when measurements from adult and fetal blood with 100% fetal hemoglobin are compared. Fetal hemoglobin is present in concentrations varying from 10% to 90% in neonatal blood, and this percentage declines over time. As the percentage of fetal hemoglobin in
neonatal blood declines, the theoretical effect on accuracy due to this source is reduced

Alarm Information
2.10.1
Basics
• There are two types of alarms:
• Physiological alarms: The physiological parameters of the monitored patient
exceed the specified ranges, or the physiological exceptions of the patient cannot be
judged according to a single physiological parameter.
• Technical alarms: The patient cannot be monitored normally and accurately due to
faults in manual operation, technical faults, or faults in the monitor.
• The high priority alarm indicates only physiological alarms and a low battery alarm.
• The low priority alarm indicates only technical alarms, other than low battery.
• The Accutorr V provides functionality for selecting the upper limit and lower limit of each
physiological alarm.
2.10.2
Alarm Notification
1. When an alarm occurs, the system notifies the user through the speaker, alarm indicator,
relevant 7-segment LED digit displays, and LCD status bar.
2. When alarms of multiple levels occur simultaneously, the system notifies the user of the
alarm with the highest level through the speaker and alarm indicator.
3. If the hospital Nurse Call system is available and connected to the monitor, the user can
be notified of relevant alarms through the Nurse Call system.
2.10.3
Audio Alarm Pause, Audio Alarm Off, and Audio Alarm Silencing
The monitor provides functionality for pausing (disabling) an audio alarm for 120 seconds.
After 120 seconds, the audio alarm notification functionality resumes. The user can resume
the audio alarm notification at any time. An alarm causes the monitor to terminate the
paused state.
• The monitor provides the ability to turn the audio alarm off globally. During audio alarm
off, a remind signal reminds the user every minute.
• The monitor provides the ability to silence an alarm. The monitor automatically exits the
alarm silenced status if a new technical or physiological alarm occurs.
2.11
Configuration management
The monitor provides a factory configuration and a user configuration. The monitor loads the
selected configuration when it is switched on. If no user configuration exists, the factory
configuration is automatically loaded.
2.12
Barcode scanner
The monitor can admit a patient using the barcode scanner.
