GE Datex Ohmeda single-use gas sampling lines — a selection guide

A selection guide for GE Datex Ohmeda sampling lines: connector types, length, packaging. Answers to the questions that come up most often about replacement and use.

During anesthesia monitoring the sampling line carries the patient's exhaled gas to the gas analyzer of the anesthesia machine or monitor. A leak or a blockage in the line directly affects measurement accuracy.

Product characteristics

GE Datex Ohmeda single-use sampling lines are made for:

  • •Datex Ohmeda AS/3
  • •Datex Ohmeda S/5

They are made from medical-grade materials, intended for single use and disposal, and meet infection-control requirements. The inner surface is smooth, which minimises adsorption and keeps the sample accurate.

Selection criteria

Three parameters have to be confirmed when choosing a sampling line:

  1. Connector type: make sure it matches the sample port of the anesthesia machine or monitor (Luer or quick-connect)
  2. Length: standard length is 1.5–2.4 m; too long increases the response time, too short restricts patient movement
  3. Packaging: bulk packs are usually 25 or 50 per box

Signs of a fault

A blocked line:

  • •The monitor shows a flattened CO₂ curve
  • •EtCO₂ values are suspiciously low or missing
  • •"Sample error" alarm

A leaking line:

  • •Fluctuating gas monitoring readings
  • •A reduced sampling rate
  • •No stable capnogram can be obtained

Rules of use

  • •Use once only, and dispose of the line after use
  • •Do not kink or clamp the line while it is in use
  • •Store in a dry place at room temperature
  • •Check that the packaging is intact before use

Conclusion

The sampling line is an important element of the breathing circuit, and the accuracy of gas monitoring depends on it directly. Use only original GE Datex Ohmeda single-use lines and replace them promptly at any sign of a fault.

Frequently asked questions

Can a single-use GE sampling line be reused?
No. A single-use line is intended for one use and guarantees the absence of residue and cross-contamination. Reuse reduces measurement accuracy and breaks infection-control protocols.
What should be done if the sampling line becomes blocked?
When the data look wrong (a flattened CO₂ curve), replace the line immediately. Do not blow it through with compressed gas — that can damage the flow sensor.
How does a leak in the sampling line show up?
The main signs are low or unstable gas monitoring readings, and an alarm such as "Sample error" or "Low sample rate" on the monitor.
Where can I buy original GE Datex Ohmeda sampling lines with delivery to Russia?
Medicaparts offers direct supplies of original single-use GE Healthcare sampling lines to Russia and CIS; lead time is confirmed when the order is placed. Contact us on Telegram @GEpartsV_bot.
