A Chinese alligator in heliox: formant frequencies in a crocodilian [PDF]

Journal of Experimental Biology, 2015
ABSTRACT Crocodilians are among the most vocal non-avian reptiles. Adults of both sexes produce loud vocalizations known as ‘bellows’ year round, with the highest rate during the mating season. Although the specific function of these vocalizations remains unclear, they may advertise the caller's body size, because relative size ...

Helium-oxygen in bronchiolitis-A systematic review and meta-analysis. [PDF]

Pediatr Pulmonol, 2022
Abstract Introduction Bronchiolitis is common reason for infant hospitalization. The aim of our systematic review and meta‐analysis was to evaluate helium–oxygen (heliox) in bronchiolitis. Methods We screened 463 studies, assessed 22 of them, and included six randomized controlled trials.

Heliox for croup in children [PDF]

Cochrane Database of Systematic Reviews, 2013
Croup is an acute viral respiratory infection with upper airway mucosal inflammation that may cause respiratory distress. Most cases are mild. Moderate to severe croup may require treatment with corticosteroids (the benefits of which are often delayed) and nebulised epinephrine (adrenaline) (the benefits of which may be short-lived and which can cause ...

Therapeutic gases used in balneotherapy and rehabilitation medicine - scientific relevance in the last ten years (2011 – 2020) - Synthetic literature review [PDF]

Balneo and PRM Research Journal, 2021
: Background. The medical relevance of therapeutic gases can range from use in burns and stroke victims to hypoxia therapy in children. However, medical gases such as oxygen, hydrogen, helium and xenon have recently come under increased exploration for

Effects of heliox and non-invasive neurally adjusted ventilatory assist (NIV-NAVA) in preterm infants

Scientific Reports, 2021
Due to its unique properties, helium–oxygen (heliox) mixtures may provide benefits during non-invasive ventilation, however, knowledge regarding the effects of such therapy in premature infants is limited.

Consequences of group III/IV afferent feedback and respiratory muscle work on exercise tolerance in heart failure with reduced ejection fraction

Experimental Physiology, Volume 108, Issue 11, Page 1351-1365, 1 November 2023., 2023
Abstract Exercise intolerance and exertional dyspnoea are the cardinal symptoms of heart failure with reduced ejection fraction (HFrEF). In HFrEF, abnormal autonomic and cardiopulmonary responses arising from locomotor muscle group III/IV afferent feedback is one of the primary mechanisms contributing to exercise intolerance.

Outcomes of a respiratory therapist driven high flow nasal cannula management protocol for pediatric critical asthma patients

Pediatric Pulmonology, Volume 58, Issue 10, Page 2881-2888, October 2023., 2023
Abstract Introduction This study aimed to determine if a respiratory therapist (RT)‐driven high flow nasal cannula (HFNC) protocol could decrease duration of HFNC use, pediatric intensive care unit (PICU) and hospital length of stay (LOS), and duration of continuous albuterol use in pediatric patients with critical asthma.

Heliox delivered by high flow nasal cannula improves oxygenation in infants with respiratory syncytial virus acute bronchiolitis

Jornal de Pediatria, 2018
Objective: The objective of this study is to evaluate the hypothesis that use of heliox would result in improvement of gas exchange when used with high flow nasal cannula in infants with RSV acute bronchiolitis.

Applying behaviour change theory to speech and language therapy intervention for inducible laryngeal obstruction

International Journal of Language &Communication Disorders, Volume 58, Issue 5, Page 1539-1550, September/October 2023., 2023
Abstract Background Speech and language therapists (SLTs) provide interventions for inducible laryngeal obstruction (ILO) despite a current lack of evidence to inform intervention delivery. This study is the first step to develop an evidence‐based intervention for ILO, using behaviour change theory and the Behaviour Change Technique Taxonomy version 1 (

Heliox allows for lower minute volume ventilation in an animal model of ventilator-induced lung injury. [PDF]

PLoS ONE, 2013
BACKGROUND:Helium is a noble gas with a low density, allowing for lower driving pressures and increased carbon dioxide (CO2) diffusion. Since application of protective ventilation can be limited by the development of hypoxemia or acidosis, we ...
