OVERVIEW Principles of Operation Displays, Controls, and Connectors
The monitor incorporates Oridion’s Microstream capnography technology. PRINCIPLES OF OPERATION The monitor uses Microstream non-dispersive infrared (NDIR) spectroscopy to continuously measure the amount of CO2 during every breath, the amount of CO2 present at the end of exhalation (EtCO2) and during inhalation (FiCO2), and the Respiratory Rate. Infrared spectroscopy is used to measure the concentration of molecules that absorb infrared light. Because the absorption is proportional to the concentration of the absorbing molecule, the concentration can be determined by comparing its absorption to that of a known standard. The Microstream EtCO2 consumables deliver a sample of the inhaled and exhaled gases from the ventilator circuit or directly from the patient (via an oral/nasal cannula) into the monitor for CO2 measurement. Moisture and patient secretions are extracted from the sample while maintaining the shape of the CO2 waveform. The 50 ml/min. sampling flow rate reduces liquid and secretion accumulation, decreasing the risk of obstruction in the sample pathway in humid ICU environments. Once inside the Microstream CO2 sensor, the gas sample goes through a microsample cell (15 microliters). This extremely small volume is quickly flushed, allowing for fast rise time and accurate CO2 readings, even at high respiration rates. The Microbeam IR source illuminates the microsample cell and the reference channel. This proprietary IR light source generates only the specific wavelengths characteristic of the CO2 absorption spectrum. Therefore, no compensations are required when different 7
OVERVIEW
concentrations of N2O, O2, anesthetic agents, and water vapor are present in the inhaled and exhaled breath. The IR that passes through the microsample cell and the IR that passes through the reference channel are measured by the IR detectors. The microcomputer in the monitor calculates the CO2 concentration by comparing the signals from both channels. Microstream EtCO2 Consumables The following products comprise the Microstream EtCO2 consumables: Intubated • FilterLine Set (for non-humid environments)
•
FilterLine H Set (for humid environments)
Non-intubated • Smart CapnoLine Oral Nasal Cannula– for use in procedural sedation. Also available with O2 delivery.
•
CapnoLine H – for use in ICU for patients receiving hi-flow oxygen by mask or on long term CPAP or Bi-PAP. Also available with O2 delivery.
•
NIV-Line – for use under oxygen CPAP, Bi-PAP or NPPV mask and to avoid intubation during EMS transport
Special Procedure FilterLines • FilterLine XL – Provides extended length so that the monitor can be used safely during MRI. (see MRI Scanning, page 38) Note: The generic term FilterLine, used in this manual, is interchangeable with any of the Microstream EtCO2 consumables. FilterLine The FilterLine has five active elements that work together to offer a solution to the problems that have previously posed challenges to

OVERVIEW
capnography in ICU, emergency, and transport applications. These elements are described below. *
Hydrophobic filter
The hydrophobic filter is located at the end of the sample line that is closest to the capnograph. This filter strips the remaining water vapor from the gas sample while keeping a laminar flow of the gas. This laminar flow minimizes distortion of the CO2 waveform. *
Drying element
The drying element is a tube made of a synthetic material that is chemically stable and has high water absorption. This material allows the water vapor to pass outside the tube, thereby adjusting the humidity inside the FilterLine close to the level of humidity in the ambient air. *
Sample line
The sample line has low dead space due to its small internal diameter. This provides a sharp waveform and an accurate CO2 reading at a high breath rate per minute. The sample line is not affected by gases and anesthetic agents in the operating room environment. *
FilterLine Recognition Safeguard
When the FilterLine is attached to the monitor, the FilterLine Recognition Safeguard (FRS) identifies the FilterLine and activates the monitor, thus enabling measuring. *
Airway Adapter
The airway adapter design provides multiple channels for the sampled air from the airway minimizing the possibility of water infiltration or line blockage. These multiple channels allow uninterrupted monitoring for all adapter orientations and in all applications. The airway adapter provides optimal performance in all directions and is seldom disabled by secretions or liquids. 9
