A review of the use of high flow nasal cannula oxygen therapy in hospitalized children at a regional hospital in the Cape Town Metro, South Africa
Background: High-flow nasal cannula oxygen (HFNC) is a non-invasive alternative to nasal continuous positive pressure oxygen (CPAP) therapy for infants and children requiring respiratory support. There is a paucity of literature to support its use in children, with no published data from …

Indication for and outcomes of continuous Positive Airways Pressure (CPAP) and High Flow Nasal Cannula oxygen therapy (HFNC) in children admitted to Red Cross War Memorial's Hospital (RCWMCH) excluding those with primary respiratory aetiologies
… Pressure (nCPAP) and High Flow Nasal Cannula oxygen therapy (HFNC) are non-invasive ventilation (NIV) modalities appropriate for children in developing countries. There is minimal literature describing nCPAP and HFNC use in children with respiratory compromise secondary to non-pulmonary …

Observational study of children with autism who have participated in hyperbaric oxgen therapy
… so does the need for research.</p> <p>Hyperbaric oxygen therapy is one alternative treatment parents are seeking for their child with autism. When one looks at the science behind hyperbaric oxygen therapy and the physical condition of a child with autism the rationale behind the treatment becomes …

A retrospective study of sleep breathing disorder therapies and treatment attitudes among adult heart failure patients
… endurance as compared to the use of nocturnal oxygen therapy, and to examine health attitudes related to compliance with recommended treatment for SBD. A retrospective chart review was completed to determine models and variables for predicting improvements in QOL and cardiovascular endurance. …

Laser-processed parchment paper for fabrication of chronic wound dressings with selective oxygenation
… A major inhibitor of healing is suboptimal oxygenation of the wound bed. Unlike acute injuries that receive sufficient oxygen via a functional blood vessel network, chronic wounds often suffer from the lack of a proper vascular network; thus being incapable of providing sufficient oxygen for …

Design and Development of a Portable Multi-user Medical Grade Oxygen Concentrator
… pandemic has increased the demand for high-flow oxygen concentrators, particularly in resource-limited areas. There is a pressing need for an innovative, high-flow, multi-user oxygen concentrator using local materials to address this healthcare challenge. Methods: The study focused on creating a …

The Clinical Spectrum, Aetiology and Disease Progression of Children with Post-infectious Bronchiolitis Obliterans at Tertiary Paediatric Pulmonology Service in Cape Town, South Africa
… were admitted to ICU, 92% required supplemental oxygen therapy and 75% required ventilatory support. Reported cigarette smoke exposure was high (47%). Adenovirus was the most common cause of initial infection 59%. Lung hyperinflation (84%) and air trapping (78%) were the most common current chest …

The effect of stimulus threat on experimentally induced secondary hyperalgesia
… 7 – 10% of people and responds poorly to pharmacotherapy. Numbers needed to treat for first line drugs range from 4 – 8. Therefore, there is an obvious need for improved understanding of the mechanisms of neuropathic pain to inform improved treatments. Mechanistic research on neuropathic pain …

The evidence basis of diving and hyperbaric medicine - a synthesis of the high level clinical evidence with meta-analysis
Introduction: Hyperbaric oxygen therapy (HBOT) is the administration of 100% oxygen at pressures greater than 1 atmosphere. One recurrent criticism that has been made of this field is that treatment is based on little or no good clinical evidence. Aims: The primary objective of this thesis is to …

The emerging role of mesenchymal stromal cells among therapeutic options for chronic obstructive pulmonary disease
… treatment options for COPD include exercise therapy, oxygen therapy, and multiple drugs with bronchodilation activity. These therapies aim to reduce dyspnea and exacerbation frequency. Steroid resistance in COPD patients has made treatment of underlying chronic inflammation difficult. …

The hyperbaric incident monitoring study (HIMS) : an international study of incidents occuring in hyperbaric medicine units
… units, or as a consequence of hyperbaric oxygen exposure, with the aim of developing recommendations for safety improvement in hyperbaric medical practice. A review of the hyperbaric literature showed that ear barotrauma is the most frequently reported patient complication of hyperbaric …

The Effects of Altered Partial Pressures of Gas on Cognitive and Neural Function
Oxygen is central to neural function, yet the precise mechanisms and effects by which varying <br/>oxygen levels, whether through Hypoxia, Hyperoxia, or Hyperbaric Oxygen Therapy (HBOT), <br/>shape cognition and brain activity remain incomplete. This thesis adopts a novel, multi-modal …

Best-Practice Evidence Based Medicine for the Effective Management of Chronic Obstructive Pulmonary Disease (COPD)
… as part of everyday best-practice. The use of oxygen therapy for the pre-hospital management of acute exacerbations of COPD (AECOPD) is potentially dangerous when delivered at high flow, with a titrated approach associated with significantly reduced mortality. Routine use of short acting …

Design and Evaluation of a Novel Method to Noninvasively Estimate Tidal Volumes During Administration of Nasal Cannula Therapy
Administration of nasal cannula therapy tasks providers with periodically monitoring their patients and adjusting settings according to patient needs. Conventionally, providers monitor a patient's oxygen demand using pulse oximetry and a qualitative assessment of the patient's work of breathing. …
