  • Page 11: Functional Description

    S/5 Airway modules FUNCTIONAL DESCRIPTION 2.1 Measurement principle 2.1.1 CO O and Agent measurement The CO O, and anesthetic agent gas measurements are based on absorption of infrared light as it passes through the gas sample in measuring chamber in the photometer. The light absorption is measured at three wavelengths using an infrared detector.

  • Page 12: Measurement

    Datex-Ohmeda S/5 Anesthesia Monitor 2.1.2 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 is generated in a measuring cell with a strong magnetic field that is switched on and off at a frequency of 110 Hz.

  • Page 13: Agent Identification

    S/5 Airway modules 2.1.3 Agent identification The anesthetic agent identification bench identifies Halothane, Enflurane, Isoflurane, Desflurane and Sevoflurane. The bench measures the spectrum of the gas between 3.24 µm and 3.39 µm. Because the spectrum of each of the anaesthetic agents is different it is possible to identify them. The bench consists of an infrared source, a measuring chamber, a rotating filter and a detector.

  • Page 14: Patient Spirometry

    Datex-Ohmeda S/5 Anesthesia Monitor 2.1.4 Patient Spirometry In anesthesia, CMV (Controlled Mechanical Ventilation) is the mostly used ventilation mode. In this mode, mechanical breaths are delivered to the patient by a ventilator with a proper tidal volume (TV), respiration rate (RR), and inspiration/expiration ratio in time (I:E) determined by the settings of the ventilator.

  • Page 15: Main Components

    S/5 Airway modules Patient Spirometry sensor, D-lite Patient Spirometry is measured with a specific sensor, D-lite or Pedi-lite. D-lite and Pedi-lite sensors are designed to measure kinetic pressure by two-sided Pitot tube. The pressure reduction caused by measuring cross is taken into account, too, especially in small flows. Velocity is calculated from pressure difference according to Bernoulli's equation.

  • Page 16: Gas Sampling System

    Datex-Ohmeda S/5 Anesthesia Monitor 2.2.1 Gas sampling system The gas sampling system samples the measured air to the module, and removes water and impurities from it. A sampling line is connected to the water trap on the front panel. The pump draws gas through the sampling line to gas measuring units.
  • Page 17 S/5 Airway modules Gas measuring units, ACX-200 and O unit After the zero valve, the gas passes through the ACX-200 and O measuring units. In the ACX-200 measuring unit, infrared light is passed through chambers containing the main flow gas (measurement) and a chamber containing reference gas.

    S/5 Airway modules Figure 10 O/AA measurement block diagram 2.2.3 OM measuring unit The oxygen measurement is based on the paramagnetic susceptibility, which is a unique property of oxygen among all gases generally present in a breathing gas mixture. The gas to be measured and the reference gas, which usually is room air, are conducted into a gap in an electromagnet with a strong magnetic field switched on and off at a frequency of approximately 110 Hz.
