Introduction
This Technical Reference Manual Slot provides  information for the maintenance and service of 
the Patient Side Modules E-PSMP and E-PSM. 
Please also refer to “Technical Reference Ma nual” of the monitor for system specific 
information e.g. related documentation, conv entions used, symbols on equipment, safety 
precautions, system description, system installation, interfacing, functional check and planned 
maintenance. 
The E-PSMP and E-PSM modules provide general hemodynamic parameters.

Table 1 Patient Side Module options
Intended purpose (I ndications for use)
The Patient Side Module (model family E-PS M(P)) and accessories are indicated for the 
monitoring of hemodynamic parameters of all hospital patients. The hemodynamic 
parameters of the module comprise ECG including ST-segment and arrhythmia, Impedance 
respiration, NIBP, Temperature, SpO
2 (including monitoring during  conditions of clinical patient 
motion), and invasive blood pressure. Parameter E-PSMP E-PSM

Impedance respiration measurement is indicated for patients aged 3 and up. The NIBP 
measurement is indicated for patients who weigh 5 kg (11 lb.) and up. This device is indicated 
for use by qualified medical personnel only. 
Monitor software compatibility
Patient Side Module, E-PSM(P) Rev. 00 and 01 are designed for use with Datex-Ohmeda 
monitors as follows: 
−S/5 FM monitors using software L-FICU04(A) or later.
− S/5 Anesthesia Monitors using software L- ANE04(A) or later equipped with 5-Module 
Frame, F-CU5(P) or with S/5 8-Module Fram e, F-CU8. With the F-CU8, the E-INTPSM 
interface module is needed. 
− S/5 Critical Care Monitors using software L-ICU04(A) or later equipped with 5-Module 
Frame, F-CU5(P) or with S/5 8-Module Fram e, F-CU8. With the F-CU8, the E-INTPSM 
interface module is needed. 
Equipment safety symbols
When displayed on the E-PSM, E-PSMP module, indicates that protection 
against cardiac defibrillator di scharge is due in part to the accessories for pulse 
oximetry (SpO
2), temperature (T) and invasive pressure (P) measurement.

Venous stasis pressure may be lower than the values above if the patient has low blood 
pressure. The venous stasis pressure adapts to the measured mean pressure being the same 
as mean pressure but always at least the following:
Infant 20 ± 5 mmHg
Child 30 ± 5 mmHg
Adult 40 ± 5 mmHg 
Overall system accuracy:  Meets  or exceeds SP10-2002 AAMI standards
