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
