Heliox therapy for respiratory students

1. Heliox therapy
R .SAM
BSC RESPIRATORY THERAPY

2. Introduction
 Breathing gas mixture of He ( Helium 80 %) and
O2 ( Oxygen 20% )
 Discovered in 1934 by Branch

3. Characteristics
 Colourless
 Odourless
 Tasteless
 Non -toxic
 Non- carcinogic
 Non- flammable
 Does not produce effect on human organs
 Does not cross alveolar capillary membrane

4. Physiological properties
 Low density gas ( reduce flow resistance)
 Low boiling point
 Low 5450melting point
 Second lowest density gas next to hydrogen
 Density 0.52 (Kg/m³ ) in 70/30 Concentration
 Density 0.40 ( kg / m3) in 80/20 concentration

5.  Generate less airway resistance than air by decreased turbulance
and require less mechanical energy to ventilate lungs
 Work of breathing is reduced

6. Mechanism
 INCREASE TENDANCY TO LAMINAR FLOW
 DECREASE RESISTANCE IN TURBULANT FLOW

8.  Helium Diffuse 1: 8 Times faster than oxygen flow of heliox from an oxygen flowmeter 1:8 Times
than normal flow
 Decrease airflow resistance within bronchial tree in obstructive lung disease
and asthma attack

9.  Heliox increase aerosol deposition mainly
because of reduction in
Turbulance and less impaction and
Medication loss

10. Administration
VIA :
SIMPLE NASAL CANNULA
HIGH FLOW NASAL CANNUL
NON – REBREATHER MAS
. NEBULIZER
INVASIVE AND NON – INVASIVE
VENTILATOR

11. Concentration of
gas mixture
HELIUM : OXYGEN
1. 80 : 20
2. 70 : 30
3. 60 : 40
MOST COMMONLY USED
CONCENTRATION IS 80:20

12. 1.Upper Airway obstruction
2.Laryngeal obstruction
3.Subglottic stenosis
4.Acute vocal cord dysfunction
5.Bilateral vocal cord paralysis
6.Tracheobronchitis

HELIOX THERAPY
7. Endotracheal and endobronchial disease
8.Mediastinal mass compressing lung
9.COPD and Asthma exacerbations
10.Pneumonia with respiratory failure
11.Bronchiolitis
12. Ciliary dyskinesia

14. CLINICAL
APPLICATIONS OF
HELIOX THERAPY
13.Increase exercise performance
14.Diagnostic PFT to calculate FRC(
Functional Residual Capacity)
15.Pulmonary Rehabilitation
16.Congenital Diaphragmmatic
Hernia

15. 1.Anoxia
oxygen level becomes zero or absence of
oxygen
2.Hypothermia
Caused mainly in Infants while using
oxyhood
HAZARDS OF HELIOX THERAPY

16. HAZARDS
Words are badly distorted at
pitch so high as to make it
almost unintelligible because
Helium goes through vocal cord.

17. HAZARDS
Hypoxemia
Volume induced lung injury during
Mechanical ventilation
