V Use only accessories and other parts recommended or supplied by SCHILLER

AG. Use of other than recommended or supplied parts may result in injury, inac­curate information and/or damage to the unit.

V Ancillary equipment connected to the analogue and/or digital interfaces must be

certified according to the respective IEC standards (e.g. IEC/EN 60950 for data
processing equipment and IEC/EN 60601-1 for medical equipment). Furthermore
all configurations shall comply with the valid version of the system standard IEC/
EN 60601-1-1. Everybody who connects additional equipment to the signal input
part or signal output part configures a medical system, and is therefore responsi­ble that the system complies with the requirements of the valid version of the sy­stem standard IEC/EN 60601-1-1. If in doubt, consult the technical service de­partment or your local representative.

V Precautions must be observed when using high frequency devices. Use the spe-

cial high frequency SCHILLER patient cable to avoid possible signal interference
during ECG acquisition.

V There is no danger when using the ECG unit simultaneously with electrical stimu-

lation equipment. However, the stimulation units should only be used at a suf­ficient distance from the electrodes. If in doubt, the patient should be disconnec­ted from the device.

V If the patient cable should become defective after defibrillation, an electrode be-

comes displaced, or an electrode resistance is too high, a lead-off indication is
displayed in the upper right part of the screen and an acoustic alarm given.

V If the device is a part of a medical system, the original SCHILLER patient cable

must only be used with, and connected to, the patient connector on the AT-101.

1.7 Maintenance

V Danger of electric shock! Do not open the device. No serviceable parts inside.

Refer servicing to qualified technician authorised by SCHILLER only.

V Before cleaning and to isolate the mains power supply, switch the unit off and dis-

connect it from the mains by removing the plug.

2.2 Operating Philosophy Overview

AT-101

There are broadly four types of data display as follows:

Data Acquisition and ECG
Recording Screen

In this screen the real-time ECG is displayed. From this screen a continuous printout
can be initiated and/or an auto recording can be made. In auto mode 10 seconds of
ECG data is analysed and averaged and the results given on a printout. The format
and data of an auto mode printout is independent of the screen display, and is defined
in the setup screens. (See paragraph 5.2 page 34).

An auto mode recording can also be stored in the memory for later print or
transmission.

Memory Screen In this screen stored recordings can be accessed, printed and transmitted.

Patient Data Screen Patient data entry via the keypad.

Data Entry and Setup In these screens all system settings are made.

2.2.1 Initiating Functions or Tasks

Most functions and tasks are initiated by the 5 softkeys (1) situated immediately below
the LCD. The function of the softkeys varies according to the screen displayed and is
displayed on the LCD immediately above the key itself.

During data acquisition, further dedicated function keys are provided to make an auto
mode recording (START) and to stop a manual printout (STOP). The top line of the
alphanumeric keypad, additionally enables direct settings of lead group, trace speed
and sensitivity, filter on/off and other functions, for both the real-time display and
(manual) printout.

4 ЭКГ покоя

V Инструкции по наложению электродов на пациента приводятся исключительно как справочная информация. Они не заменяют решения специалиста.

4.1Наложение электродов

Цветокодировка, приведенная здесь, соответствует требованиям Кода 1 (Европейский). Цветовой эквивалент по коду 2 приведен в разделе 4.2.3.

Для получения оптимального сигнала ЭКГ и обеспечения высокого качества регистрации необходимо, чтобы сопротивление между кожей и электродом было минимальным. Для этого следует соблюдать следующие требования:

1.Убедитесь, что в помещении тепло и пациент расслаблен.

2.Побрейте область наложения электрода до того, как очистить ее.

3.Очистите область наложения электрода спиртовым тампоном

4.Нанесите слой геля на кожу в месте наложения электрода.

5.Первым прикрепите электрод С4 в пятом межреберье по среднеключичной линии.

6.Затем расположите:

–C1 в четвертом межреберье по правому краю грудины

–C2 в четвертом межреберье по левому краю грудины

–C3 между С4 и С2 на равном расстоянии

–C6 по левой среднеподмышечной линии на уровне С4

–C5 между С4 и С6 на равном расстоянии

Сопротивление электродов можно проверить на экране регистрации — см. раздел 4.3.1.

При снятии ЭКГ у ребенка иногда чисто физически трудно наложить все электроды. В этом случае электрод С4 может быть наложен с правой части грудины.

VДля записи электрокардиограммы нужно убедиться в том, что ни пациент, ни токопроводящие части наложенных на него электродов (включая нейтральный электрод), не контактируют с другим человеком или другими токопроводящими предметами (даже если они заземлены).

4.2Дополнительные комбинации отведений

4.2.1Отведения по Небу

Отведения по Небу — это биполярные грудные отведения. Они представляют особенный интерес для диагностики изменений задней стенки желудочка. Три отведения организованы в форме «малого кардио-треугольника». Дорсальное (спинное) отведение по Небу (D) измеряется между электродами Nax и Nst; переднее отведение по Небу (А) — между Nap и Nst, а нижнее (J) между точками

Nap и Nax.

Наложите электроды следующим образом:

Все остальные электроды могут быть наложены на их обычные позиции. Комбинация электродов, определенная пользователем, должна быть установлена в меню Настройки:

МЕНЮ > НАСТРОЙКА > УСТАНОВКИ ЭКГ > 4 х СЛЕДУЮЩИЙ > НЕБ (D, A, J) > ВКЛ.

См. раздел 5.2.5 для получения более подробной информации.

4.2.2Наложение электродов для дополнительных отведений

Клипсы с грудных электродов С1 — С3 должны быть отсоединены и подсоединены к электродам С7 — С9, расположенным на спине пациента. Все остальные электроды могут быть наложены на обычные позиции.

Комбинация электродов, определенная пользователем, должна быть установлена в меню Настройки:

НАСТРОЙКА > УСТАНОВКИ ЭКГ > 4 х СЛЕДУЮЩИЙ > задние и прекардиальные опции. Выберите «вкл.» или «выкл.» для визуализации дополнительных отведений.

« В процессе получения данных выберите группу отведений при помощи клавиш групп отведений.

См. раздел 5.2.5 для получения подробной информации.
