Heliox Therapy in Acute Severe Asthma
Chest, 1995To assess how patients with respiratory acidosis from acute severe asthma respond to helium-oxygen (heliox) mixtures.Consecutive case series.Urban community teaching hospital.Over a 2-year period, 12 asthmatics (mean age, 33.8 +/- 11.3 years) presented to the emergency department with acute respiratory acidosis (pH < 7.35 and PaCO2 > or = 45 mm Hg ...

More About Heliox and Bronchiolitis
Pediatrics, 2002To the Editor .— The study by Martinon-Torres et al1 using heliox therapy in infants with acute bronchiolitis makes me question the diagnosis of “bronchiolitis” in those infants. It appears from the study that the use of heliox helped to decrease the work of breathing in these infants. It is conceivable that this was achieved by its property of having

Heliox in children with airway obstruction
Pediatric Emergency Care, 1997Although helium offers an additional tool in the treatment of various airway and pulmonary problems, it has no inherent therapeutic effects. As such, it can be used only as a temporizing agent to allow time for therapeutic agents to work or for the natural resolution of the disease process.

Revue medicale de la Suisse romande, 2003
Heliox is composed of oxygen and helium and its low specific gravity allows a modification of the gas flow within the airway. Breathing heliox favors a laminar flow and therefore decreases the work of breathing. Its usefulness in the child is established in croup or in post-extubation stridor.

A Prototype Infant Incubator for Heliox Therapy
Biomedical Instrumentation & Technology, 2006Abstract Heliox (Hx) gas has been shown to improve pulmonary function in infants, but methods for its delivery are invasive and problematic. To this end, we modified an Isolette (Hill-Rom Air-Shields) infant incubator (Hxl) to deliver Hx respiratory gas mixtures noninvasively while providing thermal stability for neonatal care in the ...

Heliox Therapy in Infants With Acute Bronchiolitis
Pediatrics, 2002Objective. To assess the therapeutic effects of breathing a low-density gas mixture (heliox: 70% helium and 30% oxygen) in infants with bronchiolitis. Design. Prospective, interventional, comparative study. Setting. A pediatric intensive care unit (PICU) in a tertiary care, teaching hospital.

Effect of heliox, oxygen and air breathing on helium bubbles after heliox diving.
Undersea & hyperbaric medicine : journal of the Undersea and Hyperbaric Medical Society, Inc, 2007In helium saturated rat abdominal adipose tissue, helium bubbles were studied at 101.3 kPa during breathing of either heliox(80:20), 100% oxygen or air after decompression from an exposure to heliox at 405 kPa for one hour. While breathing heliox bubbles initially grew for 15-115 minutes then shrank slowly; three out of 10 bubbles disappeared in the ...

Heliox in upper airway obstruction.
Official journal of the Canadian Association of Critical Care Nurses, 2000The use of a helium-oxygen (heliox) mixture in patients with airway obstruction was used as early as the 1930s. Although heliox does not resolve airway obstruction, it decreases airway resistance providing time to allow other treatments to become therapeutic, and thus, possibly preventing the need for intubation and mechanical ventilation.

[Heliox in acute severe asthma].
Revue medicale suisse, 2008In acute severe asthma, the use of heliox can reduce dyspnea, when the patient is spontaneously breathing as well as in mechanical ventilation. This effect is due to a decrease in airway resistance. A better penetration of aerosolized bronchodilators has also been observed. However, the clinical benefit of these physiological measurable effects remains
