English Update for Acuity System

This document describes changes in operation for the Acuity Central Monitoring System
(software version 6.31.01). This document replaces information in the following manuals:

• 810-1598-02 B Acuity System Directions For Use (software version 6.3X)

• 810-1600-02 B Acuity LT and Mobile Acuity LT Wireless System Directions For Use
(software version 6.3X)

For other operating information not contained in this document, refer to the preceding
manuals.

Heart Rate Calculation

Understanding Differences Between Acuity System and Monitor

It is possible for the Acuity Central Station with Arrhythmia Analysis Option to display a
different heart rate than the bedside patient monitor.

• The Acuity System with the Arrhythmia Analysis Option calculates the patient heart
rate by using the Mortara arrhythmia library analysis algorithms that are integrated
into the Acuity System software. This approach analyzes beat morphology using
multiple leads (when available). The result is a more sophisticated assessment of
heart rate that is less affected by noise and other artifact. Noise and other artifact can
affect the single-lead heart rate calculation performed by the bedside monitor. The
Acuity System heart rate is also in greater harmony with the ECG waveform,
arrhythmia detection, and arrhythmia event alarms.

• The bedside monitor displays the heart rate that it calculates using the single-lead
heart rate analysis. It does not use arrhythmia analysis. It is possible that this heart
rate may be different from the heart rate at the Acuity Central Station. The differences
are most likely to occur with rare ECG morphologies, such as “tall ‘T’ waves,” certain
paced rhythms, and noise or artifact.

2 Chapter 1 English Update for Acuity System Welch Allyn Acuity System

Understanding Differences in Heart Rate Alarms

The possible differences between ECG-based heart rates at the Acuity Central Station and
the bedside ECG monitor can affect the frequency of heart rate alarms. For example,
when heart rate alarm limit settings are the same at the Acuity Central Station and the
bedside monitor, the bedside monitor could display a higher heart rate (due, perhaps, to
noise or artifact) and present a heart rate alarm event at bedside.

For patients monitored using a Propaq CS or Encore monitor, if a high-quality pulse
oximetry waveform is available for the patient, you can try selecting pulse rate oximetry
as the heart rate source. This may result in a more accurate heart rate, thereby reducing
erroneous or nuisance heart rate alarm events at the bedside monitor.

To select pulse rate oximetry as the heart rate source:

• From Main Menu, press SETUP, MORE to access Setup Menu 2.

• Press NEXT as needed to highlight the HR/PR selection for SELECTED SOURCE
(typically set to ECG).

• Press CHANGE as needed to highlight SpO2.

• Press Home or MAIN MENU key to exit.

Acuity Message for Monitor Heart Rate Alarm

If a heart rate alarm occurs at the bedside monitor but does not occur at the Acuity
Central Station for a defined period of time (see table below), the Acuity Central Station
displays an equipment alert to inform the operator of this condition:

When the heart rate alarm is no longer occurring at the bedside monitor, the Acuity
system dismisses this message. The operator can also dismiss the message.

Acuity System with
Arrhythmia Option

ST Analysis ST Analysis can be performed for any or all of seven leads, depending on the operator selection.

Heart Rate Heart rate information is available in the trend data which can be viewed on the display or printed.

Determined by monitor (displayed at monitor)

Heart rate = 60 / latest average interval in seconds.
For higher heart rates, latest average interval = 7/8 of previous average interval + 1/8 of latest
interval
For lower heart rates, latest average interval = 3/4 (previous average interval) + 1/4 latest interval.
Transition rates for choice of formula include hysteresis and are 70 and 80 beats per minute.

Determined by Acuity Arrhythmia Option software (displayed at Acuity Central Station)

The beat-to-beat heart rate (HR) value is calculated as follows:

HR = 60000/actual RR (bpm).
Actual RR = time between last detected QRS complex and previously detected QRS complex
(ms).
Average HR is calculated on the basis of the mean RR interval in the last 6 seconds or 8 RR
intervals (whichever is shorter).

Arrhythmia Analysis Option

The operator can select a measurement offset.

ST segment shifts are recorded in continuous trend data every second. The operator can inspect
trend data to see the duration and elevation or depression for each episode for any time period
recorded. The operator can also inspect a summary of ST segment shift data within tabular trends.

The operator can inspect the trend data to see the lowest, highest, and median (averaged) heart
rates. Trend data also includes the total beats per range of time.

Definition of Pause
Arrhythmia Event

A pause is defined as the R-R interval which is greater than or equal to two times the average R-R.

Herzfrequenzberechnung

Unterschiede zwischen Acuity-System und Monitor

An einer Acuity-Zentralstation mit Arrhythmieanalyseoption kann eine von der am
bettseitigen Monitor des Patienten abweichende Herzfrequenz angezeigt werden.

• Das mit der Arrhythmieanalyseoption ausgestattete Acuity-System berechnet die
Herzfrequenz des Patienten mit Hilfe von Analyse-Algorithmen, die in die Software
des Acuity-Systems integriert sind und die die Mortara-Arrhythmie-Bibliothek
verwenden. Bei diesem Verfahren wird die Herzschlagmorphologie unter Einsatz
mehrerer Ableitungen (sofern verfügbar) analysiert. Hieraus resultiert eine
differenziertere Bewertung der Herzfrequenz, die weniger stark von Störungen und
anderen Artefakten verfälscht ist. Störungen und andere Artefakte können die am
bettseitigen Monitor mittels nur einer Ableitung durchgeführte
Herzfrequenzberechnung nachteilig beeinflussen. Die vom Acuity-System
bestimmte Herzfrequenz befindet sich außerdem in höherer Übereinstimmung mit
der EKG-Kurve, der Arrhythmie-Erkennung und den Arrhythmie-Ereignisalarmen.

• Am bettseitigen Monitor wird die Herzfrequenz angezeigt, die der Monitor anhand der
Herzfrequenzanalyse mit nur einer Ableitung berechnet. Hierbei wird keine
Arrhythmieanalyse eingesetzt. Es ist möglich, dass diese Herzfrequenz von der an der
Acuity-Zentralstation angezeigten Frequenz abweicht. Ein Auftreten solcher
Abweichungen ist bei seltenen EKG-Morphologien wie „hohen 'T'-Wellen“,
bestimmten stimulierten Rhythmen oder Störungen bzw. Artefakten am
wahrscheinlichsten.

14 Kapitel 2 Deutsches Update für das Acuity-System Welch Allyn Acuity-System

Unterschiede zwischen Herzfrequenz-Alarmen

Die möglichen Unterschiede zwischen EKG-basierten Herzfrequenzen an der Acuity­Zentralstation und Herzfrequenzen am bettseitigen EKG-Monitor können sich auf die
Häufigkeit der Auslösung von Herzfrequenz-Alarmen auswirken. Wenn beispielsweise die
Einstellungen der Herzfrequenz-Alarmgrenzen an der Acuity-Zentralstation und dem
bettseitigen Monitor identisch sind, könnte am bettseitigen Monitor eine höhere
Herzfrequenz angezeigt werden (möglicherweise durch Störungen oder Artefakte
verursacht) und somit bettseitig ein Herzfrequenz-Alarmereignis darstellen.

Bei Patienten, die mit einem Propaq CS- oder Encore-Monitor überwacht werden, können
Sie versuchen, die Pulsfrequenzoximetrie als Herzfrequenzquelle einzustellen, wenn für
diesen Patienten eine Pulsoximetriekurve von hoher Qualität zur Verfügung steht. Dieses
Vorgehen kann zu einer exakter erkannten Herzfrequenz führen, wodurch sich die
Häufigkeit von Herzfrequenz-Fehlalarmen am bettseitigen Monitor verringern würde.

So stellen Sie Pulsfrequenzoximetrie als Herzfrequenzquelle ein:

• Im Hauptmenü drücken Sie SETUP, WEITER, um ins Setup-Menü 2 zu gelangen:

• Drücken Sie so oft WAHL wie nötig, um den Eintrag „HF/PF“ für GEWÄHLTE
QUELLE (normalerweise auf EKG eingestellt) zu markieren.

• Drücken Sie so oft ÄNDERN wie nötig, um „SpO2“ zu markieren.

• Drücken Sie die Taste „Pos 1“ oder HAUPTMENÜ, um das Menü zu verlassen.

Acuity-Meldung für Monitor-Herzfrequenz-Alarm

Tritt über einen festgelegten Zeitraum (siehe folgende Tabelle) am bettseitigen Monitor
ein Herzfrequenz-Alarm auf, an der Acuity-Zentralstation aber nicht, dann zeigt die Acuity­Zentralstation einen Gerätealarm an, um den Bediener über diesen Zustand zu
informieren:

Wenn der Herzfrequenz-Alarm am bettseitigen Monitor nicht mehr auftritt, hebt das
Acuity-System diese Meldung auf. Die Meldung kann ebenfalls vom Bediener aufgehoben
werden.
