Introduction The E-series modules are white modules with GE parameter connectors for ECG, SpO2, NIBP, temperature and invasive blood pressure measurements. The modules are designed for use with Datex-Ohmeda S/5TM Anesthesia Monitor, S/5TM Critical Care Monitor, S/5TM Compact Anesthesia Monitor, and S/5TM Compact Critical Care Monitor. Additionally, the E-PSM(P) module is also designed for use with Datex-Ohmeda S/5TM FM.

Figure 1

Datex-Ohmeda parameter E-modules, record keeping keyboard and Remote Controller

Plug-in modules The E-modules are plug-in modules that can be plugged into F-CU8 and F-CU5(P) Module Frames. The modules can be removed or inserted during monitoring. NOTE: The M-series and E-series measurement modules can both be used in the F-CU8 and F-CU5(P) Module Frames.

General module description

(1) Insertion guide slot (2) Module keys (3) Cable connectors (4) Module release latch The F-CU8 Module Frame provides places for up to four double-width or eight single-width modules. The F-CU5(P) Module Frame provides places for up to five single-width or two double-width modules (plus one slot for one single-width module). Up to two F-CU5(P) Module Frames can be connected together, thus providing ten single width module slots. The Extension Frame used with F-CU8 provides four additional module places.

Patient Side Module Datex-Ohmeda Patient Side Module, E-PSM(P) Rev.00 is designed for use with Datex-Ohmeda monitors as follows: − S/5 FM monitors using software L-FICU03(A) or later. − S/5 Anesthesia Monitors using software L-ANE04(A) equipped with 5-Module Frame, F-CU5P or with 8-Module Frame, F-CU8. With F-CU8, the E-INTPSM interface module is needed. − S/5 Critical Care Monitors using software L-ICU04(A) equipped with 5-Module Frame, F-CU5P or with 8-Module Frame, F-CU8. With F-CU8, the E-INTPSM interface module is needed.

Keyboards Monitoring is controlled through the keys on the detachable Command Bar, fixed command board, anesthesia record keeping keyboard, Remote Controller and modules.

Remote Controller The Remote Controller, K-(C)REMCO, brings the Command Bar functions near to the user and gives access to the same menus as the Command Bar. The Remote Controller has keys that start or end a function immediately, like module keys. These direct access keys help in most common situations and tasks.

Introduction

Module overview The same modules can be used in the Anesthesia Monitor, Compact Anesthesia Monitor, Critical Care Monitor and Compact Critical Care Monitor. The patient accessories for the modules are the same as well. Most of the modules contain several parameters. The following tables show the parameters for each module. The asterisk (*) in the parameter column indicates that the module measures the parameter referred to in the column heading. A number in the parameter column indicates that the module measures the parameter referred to in the column heading and the number of module connectors for that specific parameter.

Introduction

Avoiding identical modules Modules that measure the same parameter are considered identical. Do not use them in the same monitor simultaneously. NOTE: Corresponding M-series and E-series modules are considered identical. To monitor:

Select only one of the following modules:

ECG (E), NIBP (N), SpO2 (S), Temp (T), Pressure (P) or Resp (R)

E-PRESTN, E-PRETN, E-RESTN, E-PSM or E-PSMP. NOTE: E-PRESTN, E-PRETN, E-RESTN, E-PSM and E-PSMP work only with L-ANE04(A) and L-ICU04(A) software or later versions.

Pressure (P)

E-P or E-PT. NOTE: E-P or E-PT can be used together with E-PRESTN, E-PRETN, E-RESTN, E-PSM, E-PSMP or E-PP. NOTE: E-PP can be used for additional pressure measurements with E-P. E-PT, E-PRESTN, E-PRETN, E-RESTN, E-PSM and E-PSMP.

Separate SpO2 measurement

E-NSAT NOTE: E-NSAT can be used with E-PRESTN, E-RESTN, E-PSM and E-PSMP. The SpO2 measurement in E-NSAT automatically overrides the SpO2 measurement in these modules.

Compact Airway Modules

Introduction This Technical Reference Manual slot provides information for the maintenance and service of the Datex-Ohmeda S/5 Compact Airway modules. The Compact Airway modules are double width plug-in modules. E-CO, E-COV, E-COVX, E-CAiO, E-CAiOV, E-CAiOVX and E-CAiOVX/SERVICE are designed for use with the S/5 Monitors. Later in this manual modules may be referred to without S/5 for simplicity. The service menu is described in a separate “Service Menu“ slot and the spare part lists in the “E-Modules Spare Parts” slot. The Compact Airway modules provide airway and respiratory measurements. Letters in the module name stand for: C = CO2 and N2O, O = patient O2, V = patient spirometry, X = gas exchange, A = anesthetic agents, and i = agent identification

About E-CAiOVX/SERVICE module The E-CAiOVX/SERVICE module is meant for service purposes only. It can be used as a loan module, if the module in the hospital should be sent to the factory for repair. The specifications that apply to the E-CAiOVX apply also to the E-CAiOVX/SERVICE module. **Module differences: the colour of the front mask is green, the front panel has a “SERVICE” text and there are no front panel keys equipped.

NOTE: The Compact Airway Module or Single-Width Airway Module and Airway Module, G-XXXX, cannot be used simultaneously in the same monitor. NOTE: The Compact Airway modules cannot be used in the Extension Frame, F-EXT4. NOTE: Anesthetic agents and N2O values are not displayed with Critical Care main software, but when present in the module they are calculated for compensation of CO2 and O2.
