    Respiratory Modules, E-sCAiOVX, E-sCAiOV, E-sCAiO, E-sCOVX, E-sCOV, E-sCO Product overview 1.1 Introduction This document provides information for the maintenance and service of the CARESCAPE Respiratory modules, E-sCO, E-sCOV, E-sCOVX, E-sCAiO, E-sCAiOV, and E-sCAiOVX. The CARESCAPE Respiratory modules are single width plug-in modules. The CARESCAPE Respiratory modules provide airway and respiratory measurements.
  • Page 252 Module Frames and Modules System compatibility The CARESCAPE Respiratory Modules can be used for respiratory monitoring in the following host systems: • CARESCAPE Monitor B850 • CARESCAPE Monitor B650 • CARESCAPE Monitor B450 (gas exchange measurement not supported). NOTE: The Neonatal Intensive Care Unit (NICU) software package of the CARESCAPE modular patient monitors may not support the use of CARESCAPE Respiratory Modules.

  • Page 254: Measurement Principle

    Module Frames and Modules 1.2.2 O measurement The differential oxygen measuring unit uses the paramagnetic principle in a pneumatic bridge configuration. The signal picked up with a differential pressure transducer unit is generated in a measuring cell with a strong magnetic field that is switched on and off at a main frequency of 164 Hz.

  • Page 258: Gas Sampling System

    Module Frames and Modules 1.3.2 Gas sampling system The gas sampling system draws a 120ml/min sample from the patient's airway to the module. The sampling system also takes about 30ml/min flow of room air to the oxygen sensor. When the gas sensors are zeroed, room air is taken through the CO -absorber to the gas sensors instead of the sampled gas from the patient's breathing.
  • Page 259 Respiratory Modules, E-sCAiOVX, E-sCAiOV, E-sCAiO, E-sCOVX, E-sCOV, E-sCO D-fend Pro(+) water trap The gas sampling line is connected to the input of the water trap where a special membrane passes gases and vapors but stops liquids. The gas flowing through the membrane continues via the main flow connector of the water trap to the module.
  • Page 260 Module Frames and Modules Working pressure transducer The working pressure transducer measures absolute working pressure near the MiniTPX unit and MiniOM unit. It is used for messages: ‘Sample line blocked’, ‘Check D-fend’, ‘Replace D-fend’ and ‘Check sample gas out’. Pneumatics unit The pneumatics unit contains the zero valve, the occlusion valve and the pneumatics block with tubing connections.

All gas lines to the sensor must also be carefully assembled so that they do not pick up mechanical vibrations of the module mechanics.

  • Page 264: Minipvx Measuring Unit

    Module Frames and Modules The factory calibration coefficients of the sensor are stored in an EEPROM memory on the miniOM board. When the module starts up, the calibration coefficients are read to the module CPU and then used for calculating the O2 concentration from the Oxygen raw data received from the sensor.

    Module Frames and Modules 1.2 Measurement principle 1.2.1 CO O, and agent measurement TPX is a side stream gas analyzer, measuring real time concentrations of CO O, and anesthetic agents (Halothane, Enflurane, Isoflurane, Desflurane, and Sevoflurane). Figure 2 TPX sensor principle Anesthetic agents or mixtures of two anesthetic agents are automatically identified, and concentrations of the identified agents are measured.
  • Page 325 Compact Airway Modules, E-CAiOVX, E-CAiOV, E-CAiO, E-COVX, E-COV Identification of anesthetic agents and calculation of their concentrations is performed by measuring absorptions at five wavelengths in the 8-9 μm band and solving the concentrations from a set of five equations. Figure 4 Infrared absorbance of AAs The measuring accuracy is achieved utilizing numerous software compensations.

    Module Frames and Modules 1.2 Measurement principle Entropy is a measure of irregularity in any signal. During general anesthesia, EEG changes from irregular to more regular patterns when anesthesia deepens. Similarly, FEMG quiets down as the deeper parts of the brain are increasingly saturated with anesthetics. The Entropy Module measures these changes by quantifying the irregularity of EEG and FEMG signals.
