Cardiocap/5 Technical Reference Manual

1.2 Cardiocap/5 models and features

The Cardiocap™/5 is a configured monitor that is intended for indoor monitoring of the hemodynamic, respiratory, relaxation, and ventilatory status of the patient. Two models of the monitor are available: hemodynamic (F-MX) and hemodynamic with airway gas measurement (F-MXG). Both models can be equipped with built-in options.

• All measurement parameter options (and the Recorder option, N-XREC) are factory-configured

and cannot be added after purchase.

• Data collection and management options (N-XNET and N-XDNET) can be added later, if the CPU

board supports Network functionality.

1.2.1 Options for hemodynamic model (F-MX)

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.

Overview

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 SpO

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.

interface board.

• 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.

1-4

• 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.

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.

Overview

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.

2.4.3 Interfacing other devices using the analog/digital output connector

The analog/digital output connector (X1) can be used to interface other devices to the Cardiocap/5.

Digital outputs

Defibrillation sync

The ECG generates the defibrillation sync digital output signal. The signal is set to a high state (logic 1: 2.8 to 5.0 VDC ) when activated. After 10 ms, it is set back to a low state (logic 0: 0 to 0.8 VDC). The signal is regenerated only after returning to the low state. The delay from the R-wave peak to the start of the signal is 35 ms maximum.

Nurse call

The nurse call digital output signal is generated by red, yellow, and white alarms. When activated, the signal is set to a high state and remains at a high state until the alarm situation is over or the Silence Alarms key is pressed. The high state (logic 1) ranges from 2.8 to 5.0 VDC while the low state (logic 0) ranges from 0 to 0.8 VDC. The nurse call signal also activates a relay that connects X1 (pins 11 and 12).

2.6 Functional check

The functional check consists of instructions to verify the correct operation of the Cardiocap/5. The functional check is recommended after installing the monitor and after long storage.

The first part of the instructions contains procedures that are performed through the service menu. These checks are especially recommended if the monitor has been stored and not used for a long time.

When installing a new monitor, performance checks with a simulator and accessories are typically enough to ensure the correct function of the monitor. We recommend that you always perform the complete functional check to confirm that no hardware failures occurred during transport.

The instructions are for the maximum functional configuration of the Cardiocap/5. Perform the procedures in ascending order and skip items that do not correspond to your monitor configuration.
