HELIOX – GAS PROPERTIES

What is Heliox?

Heliox – HeO2 – is a mixture of helium (He) and oxygen (O2) (e.g. 80/20; 70/30).

Helium is an inert, low density gas (~1/7 the density of air and oxygen).

Lower density leads to a more laminar flow (less turbulence) and thus reduces resistance in the airways.

Laminar gas flow (A) is more efficient than turbulent flow (B).

HELIOX – GAS PROPERTIES

HELIOX – EFFECTS ON VENTILATION

Effects of Heliox therapy according to the literature

Established positive effects on ventilation

Reduces work of breathing

Increases CO2 diffusion

Potential positive effects on ventilation

Reduces the peak pressure needed to maintain flow

Increases CO2 elimination and improves gas exchange

Increases expiratory flow

Reduces respiratory rate and auto PEEP

Increases drug deposition in distal parts of the airways.

Upper airway obstruction

Lower airway obstruction

Preparations before using Heliox with SERVO-i


Automatic gas identification

Performed by the ultrasonic expiratory flow sensors

Available during Pre Use Check and during ventilation

Active as long as the set O2 concentration is 75% or below

Time for identification is determined by tidal/minute volume and O2 concentration used


Pre Use Check


Automatic identification when changing from air to Heliox during ventilation


Gas type change – manually initiated compensation for Heliox gas






Non-invasive application


Infant application
