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.

5
HELIOX GAS PROPERTIES

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

6
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.

7
HELIOX USES AND APPLICATIONS
For which patients is Heliox most commonly used?

• Upper airway obstruction
• Lower airway obstruction

18
SERVO-i WITH HELIOX OPTION
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

Things to bear in mind when using Heliox with
SERVO-i

• When system is compensated for Heliox
• Flow trigger sensitivity is automatically reduced
  to a level of 1 if set to a more sensitive level.
• O2 alarm limits are automatically adjusted from
  5 to 7.
• When ventilating below 100 ml in infant range, it
  is recommended to use additional patient
  monitoring.

25
SERVO-i WITH HELIOX OPTION
Things to bear in mind when using Heliox with
SERVO-i

• When changing gas type from air to Heliox and
  vice versa
• When changing from air to Heliox or vice versa,
  measured values relating to expiratory flow may
  be affected for a short while.
• Changing gas during ventilation may trigger O2
  concentration high and/or Gas supply pressure low
  alarms.
• After O2 concentration is changed stabilization
  of expiratory measurements may be delayed.
• During nebulization there may be a higher
  deposition of drugs used compared to when
  ventilating with air.
