Principles of an Ideal Device for Administering Helium-Oxygen Mixture

During Weaning From Mechanical Ventilation

It has identified the use of helium-oxygen (He/O2) mixture during weaning as a healthcare market. Fundamentally, helium-oxygen could provide a respite of low work of breathing to ease the patient to self-breathing. 

A part of the weaning process often includes a test period where the endotracheal tube is left in place in the patient.

The problem is that a device would be needed to administer the helium-oxygen mixture during the test period or in a ventilator-administered test and the ventilator was not equipped to use helium-oxygen.

An ideal device for doing this would include:

·         Breathing circuit consisting of tubing, T-piece, instrumentation ports, connection to endotracheal tube, one-way valves, filters, humidifier…

·         Gas supply of helium-oxygen and oxygen to a gas blender…

·         Control system for pressure.

·         Measurements: temperature, humidity, endotracheal tube pressure, tracheal pressure, flow, gas concentration…

·         Display of measurements, breathing frequency, work of breathing
