HelioxHelioxHelium is a colorless tasteless, non-combustible gas that is biologically inert and insoluble in human tissue It is seven times lighter than air. Combining helium and oxygen (Heliox) results in a gas with a similar viscosity to air but with a substantially lower density.Heliox lowers the resistance of gas flow in the airways and allows for an increase in ventilation due to changing turbulent flow into more efficient laminar flow. It also may decreases the pressure gradient needed to achieve a given level of turbulent flow which may decrease work of breathing. Use of Heliox does not treat the underlying disease, but is used to reduce airways resistance and respiratory muscle work until definitive treatments act.
Heliox HistoryHeliox History
In 1930’s BarachIt recommended Heliox In 1930’s BarachIt recommended Heliox as an adjunct therapy for treatment of as an adjunct therapy for treatment of respiratory failure from obstructions of the respiratory failure from obstructions of the larynx, trachea, and airways larynx, trachea, and airways
Use decreased in the 1940s due to the Use decreased in the 1940s due to the World War II and the loss of helium World War II and the loss of helium sources and development of sources and development of bronchodilators that were more effective. bronchodilators that were more effective.
Heliox resurfaced in the early 1980s Heliox resurfaced in the early 1980s when asthma deaths began to rise when asthma deaths began to rise despite advances in medicine despite advances in medicine
Considerations of HelioxConsiderations of HelioxHeliox usually comes in a 80/20 mixture.
There is little evidence of any severe adverse reactions for patients breathing Heliox since it is an inert gas that has no effect on human metabolism.
Helium has a high thermal conductivity and may be associated with a lowering of body temperature when used for prolonged periods.
Administration is best via a closed system as this allows the best concentration to be delivered to the patient without any mixing of room air to occur.
When using an 80/20 mix FIO2’s >0.45 negate the therapeutic effect of He/O2.
With an 80/20 mix when using an oxygen flow meter multiply by 1.8 to calculate the actual system flow.
Understanding the effects of heliox on ventilator performance.
Heliox cylinders cost about four times as much as oxygen .

Evidence of HelioxEvidence of HelioxA prospective study by Gluck showed heliox reduced peak airway pressure and PaCO2and helped correct respiratory acidosis in 7 intubated patients with status asthmaticus.
Schaeffer reported that 11 mechanically ventilated for status asthmaticus receiving heliox had improved oxygenation in adult and pediatric patients. A retrospective study by Abd-Allah heliox was used in 28 mechanically ventilated children with status asthmaticus. Heliox was associated with significantly lower mean peak pressure and mean PaCO2 , and a improved arterial pH.
Gerbeaux retrospectively studied 81 nonrandomized patients who were admitted for exacerbation of COPD and respiratory acidosis. 39 patients received 70:30 heliox and 42 did not receive heliox. There were no significant differences in age, gender, medicalhistory, Among those who received heliox, the intubation rate was lower (8% vs 50%, p 0.01), mortality was lower (3% vs 24%, p 0.01), and intensive-care-unit (ICU) admissions were lower (46% vs60%, p 0.23). Among the survivors, mean ICU stay was shorter (8 vs 18 d, p 0.01).
Gross et al found that in children mechanically ventilated for bronchiolitis, heliox did not improve oxygenation.

Nose to Brain
OptiNose has developed innovative nasal drug delivery devices that enable nasal administration of CNS (nose to
brain), systemic and topical nasal formulations. OptiNose’s unique breath actuated devices deliver intranasal drugs to
targeted regions of the nasal cavity, including the sinuses and the olfactory region, without lung deposition, unlike
traditional nasal inhalers, nasal sprays or nebulizers. The Company offers both single and multi-use intranasal delivery devices for liquid and powder formulations. Founded in 2000,
OptiNose has extensively tested the technology in both in-vitro and in-vivo deposition studies and concluded Phase I
studies. The Company has recently completed Phase II clinical studies with rhinosinusitis and migraine therapies.

Fightting the FluFightting the Flu
RELENZA (ruh-LENS-uh) is a medicine that can both treat influenza (flu, infection caused by influenza virus) and help to prevent getting the flu. While some antiviral medicines only protect against influenza A, RELENZA is effective against both influenza A and B.
RELENZA belongs to a group of medicines called neuraminidase inhibitors. These medications target the influenza virus and prevent it from spreading inside your body. RELENZA treats the cause of influenza at its source, rather than simply treating the symptoms.
Some patients have had bronchospasm (wheezing) or serious breathing problems when they used RELENZA. Many but not all of these patients had previous asthma or chronic obstructive pulmonary disease.

"Subsequent to these findings, we assume that the hormone is an overall trigger for social sentiments: when the person's these findings, we assume that the hormone is an overall trigger for social sentiments: when the person's association is positive, oxytocin bolsters pro-social behaviors; when the association is negative, the hormone association is positive, oxytocin bolsters pro-social behaviors; when the association is negative, the hormone increases negative sentiments. increases negative sentiments.
