The F-MX model can also be configured with one of the following built-in options: N-XNSAT Nellcor® compatible pulse oximetry (SpO N-XOSAT Datex-Ohmeda enhanced pulse oximetry (SpO 1.2.2 Options for hemodynamic model with airway gas measurement (F-MXG) The F-MXG measures NIBP, ECG (3-lead and 5-lead), pulse oximetry (SpO ), temperature (T1), impedance respiration, and airway gases.
Page 11: Monitor Structure
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.

, 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.
Page 13: Distributed Processing
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.

Cardiocap/5 Technical Reference Manual The PFC converter controls the intermediate voltage. The intermediate voltage has been set to about 370 V. In addition, there is a small (<10 V ) ac ripple component across capacitor C9. The frequency of this AC component is double the line frequency. 5.2.4 DC/DC converter The DC/DC converter is a forward converter.
Page 103: Over-Voltage Protection
Frames and Software Output voltage is controlled by a two-loop system. This means that there is a fast inner-voltage- control loop and a slow outer-voltage-control loop. The slow-voltage control is an external voltage signal, which, by setting the offset to the inner-control loop, determines the level of the output voltage. If the external feedback signal is not connected to pin 6 of connector X12, the output voltage measured from connector X12 settles to approximately 10 V.

Page 131: Measurement Principles For Hemodynamic Parameters
Measurement Parameters 6.2 Measurement principles for hemodynamic parameters 6.2.1 NIBP NIBP (Non-Invasive Blood Pressure) is an indirect method for measuring blood pressure. The NIBP measurement is performed according to the oscillometric measuring principle. The cuff is inflated with a pressure slightly higher than the presumed systolic pressure and deflated at a speed based on the patient's pulse.
Page 132: Invasive Blood Pressure (N-Xp Option)
Cardiocap/5 Technical Reference Manual 6.2.5 Invasive blood pressure (N-XP option) A catheter is inserted into an artery or vein to measure invasive blood pressure. The invasive pressure setup—consisting of tubing, a pressure transducer, and an intravenous bag of normal saline all connected together by stopcocks—is attached to the catheter.
Page 133: Sensor
NOTE: Only one pulse oximetry source at a time is allowed by the Cardiocap/5. When the N-XOSAT option is installed in the monitor, standard pulse oximetry and N-XNSAT are not available. The Datex-Ohmeda enhanced pulse oximetry option uses a two-wavelength pulsatile system—red and infrared light—to distinguish between oxygenated (O Hb) and reduced (HHb) hemoglobin, each of which absorbs different amounts of light emitted from the oximeter sensor.
Page 134: Calibration
Calibration Datex-Ohmeda enhanced pulse oximetry uses two wavelength ranges, 650 nm to 665 nm and 930 nm to 950 nm, both with an average power of less than 1 mW. These wavelengths are used to calculate the presence of oxyhemoglobin (O Hb) and reduced hemoglobin (HHb).
Page 135: Pulse Oximetry, Nellcor Compatible (N-Xnsat Option)
The calculation of SpO assumes 1.6% carboxyhemoglobin (COHb), 0.4% methemoglobin (MetHb), and no other pigments. These values are based on the Datex-Ohmeda Pulse Oximeter Empirical Calibration Study. Appreciable variation from these values will influence SpO accuracy.

Nerve stimulation There are three NMT stimulus modes: Train of Four (TOF), Double Burst 3,3 (DBS) and Single Twitch (ST).

Measurement Parameters Before each stimulation, the sequence offset, noise, and threshold for response detection is measured. Offset is a baseline of the noise measurement. Noise is calculated by the same algorithm as the response signal itself. The response detection threshold is calculated based on the noise. If the response is not greater than the threshold, it is interpreted as no response.

Service Procedures 7.4.2 NIBP calibration check NIBP pressure measurement electronics are calibrated at the factory. The processor maintains zeroing pressure automatically. If the zero point of the pressure transducer drifts more than specified, an error message is given and the NIBP board should be recalibrated or replaced. Checking the primary pressure channel calibration 1.
