The PneuX system is a single-use endotracheal or tracheostomy tube (ETT) designed to prevent ventilator-associated pneumonia (VAP) by minimising the risk of pulmonary aspiration and micro‑aspiration during mechanical ventilation. Aspiration occurs when secretions from the mouth leak past the cuff into the lungs. The system has 3 components: a tube, a tracheal seal monitor, and a 2 m extension tube.

It has a low-volume, low‑pressure cuff made from a soft silicone material. The tracheal seal monitor is an electronic automated pressure controller which controls and maintains safe intracuff/tracheal wall seal pressure. It has 3 subglottic secretion drainage and irrigation ports above the proximal end of the cuff so that subglottic drainage and irrigation can be done even if one of the ports is blocked. The subglottic ports are small to prevent damage to the tracheal mucosa. Subglottic drainage can also be done with PneuX. This involves using a cleaning fluid (usually saline) to wash out the space above the cuff and oro-pharyngeal space.

PneuX was formerly known as the 'Venner PneuX PY VAP Prevention System and the Lo-Trach system'. There are no functional differences between the 2 versions.

The PneuX system is not compatible with other ETTs.

Innovative aspects

An automated tracheal seal monitor/cuff pressure controller and 3 subglottic ports.

Intended use

PneuX is intended for use in people who are expected to be intubated for 24 hours or longer. There is no evidence for the use of PneuX in children.

Clinical staff will need to be trained in subglottic secretion drainage using the PneuX ports. They will need to do this at regular intervals.

The company provides training and support.


The PneuX system costs £150, based on the NHS Innovation and Technology Tariff (ITT-03 2017-19).
