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.

The AC flows through the EMI filter and the rectifier and filter. The rectifier and filter converts the AC to 16.8V DC voltage by the Flyback converter. The 16.8V DC voltage is the main input to the DC/DC converters and charging circuit. The DC/DC converters convert 16.8V DC to 12V, 5V, and 3.3V DC. The charging circuit charges the lithium battery. When the Accutorr V is not connected to the AC mains, the battery supplies power to the DC/DC converters.
The 16.8V DC output is protected against over-voltage and over-power. The 12V, 5V, and
3.3V DC outputs are protected against over-voltage, short-circuit, and over–current.

Introduction Specifications

2.1 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.

In single fault conditions, the hardware controls the cuff deflation to prevent the cuff pressure from exceeding the following ranges:
Adult 330 mmHg
Pediatric 220 mmHg
Neonate 165 mmHg

2.2.4 Cuff Inflation

The Non-Invasive Blood Pressure inflation source brings a volume of 200 ccs to a pressure of 300 mmHg in less than or equal to 10 seconds

2.2.5 Maximum Leakage

The Non-Invasive Blood Pressure Cuff driver allows a pressure drop to be, at most, 1 mmHg in 10 seconds as measured with a 200 cc volume at differential pressures of 250 mmHg, 150 mmHg, and 50 mmHg.

2.2.6 Deflation Rate

The Non-Invasive Blood Pressure Cuff venting mechanism in adult mode vents a volume of 500 cc, reduced from a pressure of 260 mmHg to a pressure of 15 mmHg in a maximum of 10 seconds.
The Non-Invasive Blood Pressure Cuff venting mechanism in neonatal mode vents a volume of 500 cc, reduced from a pressure of 150 mmHg to a pressure of 5 mmHg in a maximum of 5 seconds.

2.2.7 Update Period

The Non-Invasive Blood Pressure Parameter has an update period of one (1) second.

2.2.8 Initial NIBP Pressure Setup and Range

The initial pressure is adjustable, and should be set to the following default values:
PATIENT TYPE DEFAULT INITIAL PRESSURE ADJUST RANGE
Adult 180 mmHg 100 – 280 mmHg
Pediatric 140 mmHg 60 – 180 mmHg
Neonate 100 mmHg 40 – 120 mmHg
Manual pressure changes in increments of 5 mmHg.

NIBP Measurement Cycle Specifications

2.3 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.

2.3.2 Automatically Adjusted Inflation Value after First Measurement

In the Interval and Stat modes, the inflation value of the next measurement will be automatically adjusted by the NIBP module based on the systolic value of the previous reading. After the first unsuccessful measurement, the subsequent inflation value will be the previous systolic pressure reading plus P2:
Adult Mode: P2 = 50
Pediatric Mode: P2 = 50
Neonate Mode: P2 = 40

Alarm Information Specifications

2.10 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.
