GE Cardiocap 5 Service Manual

Overview 
1.3 Monitor structure 
The Cardiocap/5 can be equipped with several factory-configured options. The block diagram and 
descriptions that follow represent the maximum functionality of the monitor with all options installed. 
 
Figure 1-1. Cardiocap/5 monitor structure 
The main software and measurement technologies are based on AS/3 hardware and software. Some 
parameter-measuring unit boards are interchangeable with AS/3 module boards, however, the units 
cannot be replaced with the...

PVX unit for Patient Spirometry (N-XV option) 
The PVX unit connects to the CAiO unit and measures the patient’s airway flow and pressure (Patient 
Spirometry).  
CAiO unit (N-XC, N-XCO, and N-XCAiO options) 
The CAiO unit measures airway gases. It is capable of measuring CO2, N2O, O2, anesthetic agents (AA) 
and also identifying the present anesthetic agent. 
Datex-Ohmeda enhanced pulse oximetry (N-XOSAT option) 
The OSAT unit measures oxygen saturation and pulse...

Overview 
Distributed processing 
The parameter and airway measuring units contain their own microprocessor systems for performing 
low level functions, such as waveform filtering and pneumatics control. At the same time, the main 
CPU performs higher level tasks (trending and alarm control, for example). 
1.3.4 Display 
The main CPU directly controls the monitor display, a 10.4 inch color LCD. Supply voltages for the 
display are connected via the CPU board and the Backlight board. The Inverter board...

Symbols on equipment 
 
Attention! Read accompanying instructions, including all warnings and cautions, 
before using this device.  
This symbol has the following meanings when it appears on the screen: 
• On the front panel indicates that protection against cardiac defibrillator discharge is 
due in part to the accessories for pulse oximetry (SpO2), temperature (T) and 
invasive pressure (P) measurement. 
• When displayed beside the O2...

Overview 
Electrical shock hazard 
When you connect equipment to the Cardiocap/5 input and output connectors, you are configuring a 
medical system and are responsible for ensuring that the system complies with IEC/EN 60601-1-1 
and with local requirements. 
Do not touch any exposed wire or conductive surface while covers are off and the monitor is energized. 
The voltages present can cause injury or death. 
Always perform an electrical safety check and leakage current test of the monitor after service....

Cardiocap/5 Technical Reference Manual 
Always perform an electrical safety check and a leakage current test on the monitor after service. 
Handle the water trap and its contents as you would any body fluid. Infectous hazard may be present. 
Accessories 
Use only accessories, mounts and defibrillator-proof cables and invasive pressure transducers 
approved by GE Healthcare. For a list of approved supplies and accessories, see the Supplies and 
Accessories catalog. Other cables, transducers and...

Overview 
Do not apply pressurized air to any outlet or tubing connected to the monitor. 
Clean the fan dust filter on the rear panel once a month or whenever necessary. 
Electrostatic discharge through the PC boards may damage the components. Before handling printed 
circuit boards, wear a static control wrist strap. Handle all boards by their nonconductive edges and 
use antistatic containers when transporting them. 
Do not break or bypass the patient isolation barrier when testing PC boards. 
If...
