SLE6000 etCO2 module

The design of the SLE6000 allows the purchase of a number of software modules for upgrading and extending its features. It also means that in the future when you require new features and modes, or when we release a new option, it will be easier for you to update the ventilator and add these new features.

All new SLE ventilators include a core set of modes. Additional modules can be added when the ventilator is purchased, or at a later date.

Ventilator Integration

SLE has developed an optional CO2 software module for use with the SLE6000 ventilator. This requires an external hardware module, the MicroPod, that plugs into the rear panel of the SLE6000 and sends data on CO2 from the patient to the ventilator to display and trend.

Capnography

Capnography is an established non-invasive method for monitoring the level of carbon dioxide in exhaled breath (etCO2) to assess a patient’s ventilatory status. In the past, this has always been separate to the ventilator.

How it works

Microstream capnography uses non–dispersive infrared (NDIR) spectroscopy to continuously measure the amount of CO2 during every breath, particularly the amount of CO2 present at the end of exhalation (etCO2).

The Microstream etCO2 sampling lines deliver a sample of the inhaled and exhaled gases from the ventilator circuit into the monitor for CO2 measurement. Moisture and patient secretions are extracted from the sample, while maintaining the shape of the CO2 waveform. A 50 ml/min sampling flow rate is ideally suited to infant/neonatal applications.

Once inside the Microstream CO2 sensor, the gas sample goes through a micro-sample cell (15 microlitres). This extremely small volume is quickly flushed, allowing for fast rise time and accurate CO2 readings, even at higher respiration rates.

Key Benefits:

  • Respiratory gas monitoring incorporated into the ventilator interface.
  • CO2 monitoring can confirm correct placement of ET tube and adequate ventilation.
  • On-screen trends show gradual and sudden changes in CO2 output.
  • CO2 reading can be visually correlated with ventilation parameters when viewed in trend mode.
  • Allows NICUs without CO2 monitoring to add CO2 monitoring at a time that suits them.
  • Bracket available for convenient mounting on the SLE6000 trolley.
  • Microstream capnography technology offers Plug-and-Play technology — turn on monitor, attach sample line, and begin monitoring.
  • No individual patient calibration or zeroing required.
  • Automatic adjustment for changes in ambient temperature: not impacted by temperature fluctuations.
  • Low flow 50 ml/minute sample rate - effective for infant/neonatal sampling.
  • 0.2 micron sterilizing-grade filter designed to reduce risk of biohazard contamination of the monitor.
