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 corresponding modules as the hardware of the assemblies is different.
1.3.1 Measurement parameter units
The maximum Cardiocap/5 parameter measurement configuration consists of the NESTPR, PVX, and
CAiO units plus ONE of the following units: NMT or NSAT or OSAT.
The NESTPR, CAiO, and NMT units are connected to the CPU through the Mother board and
communicate with the CPU over a standard AS/3 module bus. The NSAT or OSAT pulse oximetry unit is
also connected to the CPU through the Mother board and communicates with the CPU over a standard
AS/3 module bus, which is located on the SpO2 interface board.
Each parameter measurement board contains a CPU that processes measurement data for the
parameter(s) associated with that board before sending the data to the main CPU.
NESTPR unit
The NESTPR unit contains three boards for measuring hemodynamic parameters:
• The ECG board measures ECG (3-lead and 5-lead) and impedance respiration.
• The STP board measures oxygen saturation, temperature, and invasive blood pressure.
• The NIBP board measures noninvasive blood pressure.
1-3

Cardiocap/5 Technical Reference Manual
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 rate using Datex-Ohmeda enhanced pulse
oximetry technology.
Nellcor® compatible pulse oximetry (N-XNSAT option)
The NSAT unit measures oxygen saturation and pulse rate using signal processing electronics and
software that are based on Nellcor stand-alone oximeters.
NeuroMuscular Transmission (N-XNMT option)
The NMT unit measures the relaxation status (TOF, DBS, and ST) of patients. When used with a regional
block cable, the unit acts as a nerve locator.
1.3.2 Communication
The CPU communicates with the hemodynamic parameters measuring unit (NESTPR) and airway gas
measuring unit (CAiO) over a standard AS/3 module bus. It is based on the widely used industry
standard RS485, which uses a differential serial method to transfer data and is quite robust.
RS485 serial communication supports multidrop or party line connections. This means all units
connected to the module bus use the same two physical wires for communication purposes. The
module bus uses a 500 kbps data transfer rate.
Communication with the I/O board and the DC/DC board takes place over an internal synchronous
serial bus. The same bus also controls display brightness and audio signals by means of D/A
converters located on the CPU board.
Communication with the Net takes place over a separate synchronous serial channel. Communication
with the Net is possible, if the CPU board is equipped with an Ethernet controller.
Communication with the Recorder takes place over an asynchronous serial channel.
1.3.3 CPU board
The control functions of the monitor are centralized on the CPU board. The CPU:
• Controls the power on/off sequencing.
• Controls the brightness of the LCD screen by means of the Backlight board.
• Controls the Inverter board that provides the high voltage for the display backlights.
• Reads input from the keyboard and ComWheel.
• Controls the serial channels and I/O functions of the monitor.
Two PCMCIA-compatible data card slots on the board are for loading software and transferring data.
1-4

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 provides high
voltage for the display backlights. The CPU controls the display brightness by adjusting the backlight
voltage.
1.3.5 I/O board
The I/O board contains D/A converters for analog outputs and the audio output amplifier. It also
contains connectors for the network identification plug, serial I/O, analog output, and external
keyboard.
Analog outputs are created by transferring digital data from the CPU to the D/A converters on the I/O
board through the internal synchronous serial bus. The network identification plug is connected to the
CPU over a separate synchronous serial channel.
1.3.6 DC/DC board
The DC/DC board converts 15 VDC coming from the AC/DC unit to different supply voltages for the
monitor. All outputs are short-circuit and over-voltage protected. The CPU controls the output voltages.
If the mains voltage drops, the 12 VDC back-up battery automatically supplies power to the monitor.
The battery will run the monitor for at least 15 minutes. The battery is always charged when mains
voltage is connected. The temperature sensor that measures the monitor’s internal temperature is
located on the board. The DC/DC board communicates with the CPU over the internal synchronous
serial bus.
1.3.7 AC/DC unit
The AC/DC unit converts the mains voltage to 15 VDC that is fed to the DC/DC board. The input
voltage range of the unit is 100 to 240 VAC. The DC/DC board shuts down the AC/DC unit when there
is over voltage detected on the 15 VDC output. The shutdown mode is reset by detaching the mains
power cord for 30 seconds.
1.3.8 Recorder (N-XREC option)
The Recorder prints trend data and record parameter waveforms. It connects to the CPU through an
asynchronous serial channel. Recorder supply voltages connect through a Recorder board that is
permanently attached to the recorder mounting box. The board contains a voltage filter and a delay
circuit for 12 V.
