MRI Transport Ventilator Circuit

9317 and 9318.png

A complete, lightweight, ready-to-use, non-metallic MRI transport circuit in a single small package. Compatible with Westmed BagEasy™ Manual Resuscitator, and with some portable transport ventilators that have a passive exhalation valve. Features a minimal deadspace non-rebreathing valve with a swivel patient connector, adjustable PEEP valve and a proximal monitoring port that can be used for airway pressure. Now available with Adult CO2 Easy™ Carbon Dioxide Detector: 2-inch diameter indicator is easy to read and the anti-fog lens reduces condensation from exhaled gas. Purple-to-yellow color change allows CO2 to be confirmed from a distance.


MR-Safe. The entire circuit is magnetic resonance imaging safe and is completely non-metallic, non-electrically conductive, and non-RF reactive.

Expandable Tubing. 
The packaged length of the 22 mm corrugated tubing is only 28 inches, yet the entire circuit expands up to 8 feet to allow convenient ventilator positioning away from the patient or outside of the MRI magnet.  

Single-piece Patient Valve.  
Below left – with integral adjustable PEEP capability. Below right – Monitoring port with tethered cap allows connection of external pressure gauge or sidestream capnograph for expanded monitoring capability.
