AI Article Synopsis
- Recent systematic reviews found no evidence supporting the use of oxygen in drowning treatment, prompting a study on lifeguards administering oxygen before EMS arrival.
- The study analyzed 216 drowning patients in two matched groups (oxygen vs. non-oxygen) based on age, sex, and injury severity, focusing on in-hospital mortality and other outcomes.
- Results showed no improvement in survival or oxygen levels with oxygen therapy; both groups had similar death rates and initial oxygen saturation, but the oxygen group required more positive pressure ventilation.
Article Abstract
Introduction: No published evidence was identified regarding the use of oxygen in the treatment of drowning in two recent systematic reviews. The aim of our study was to investigate the impact of on scene, pre-Emergency Medical Services (EMS) oxygen therapy by lifeguards in the resuscitation of drowning victims.
Method: We conducted a retrospective case match analysis of drowning patients presenting to the EDs of Sunshine Coast Hospital and Health Service. Patients were matched for age, sex and severity of drowning injury. The primary outcome was in-hospital mortality. Secondary outcomes included positive pressure ventilation (PPV) by EMS and the ED, as well as admission to the Intensive Care Unit.
Results: There were 108 patients in each group. Median (IQR) age was 22 (15-43) in the oxygen group and 23 (15-44) years in the non-oxygen group. There were 45 females in the oxygen group and 41 females in the non-oxygen group. Sixteen patients had suffered cardiac arrest and three patients respiratory arrest in each group. There were five deaths in each group. Initial oxygen saturation on arrival of EMS was identical in both groups 89.2% (±19.9) in the oxygen group versus 89.3% (±21.1) (P = 0.294) in the non-oxygen group. The oxygen group required PPV more frequently with EMS (19 vs 11, P < 0.01) and in the ED (19 vs 15, P < 0.01).
Conclusion: On scene treatment with oxygen by lifeguards did not improve oxygenation or outcomes in drowning patients.

Maximal oxygen uptake (VOmax) in healthy subjects is primarily limited by systemic oxygen delivery. In chronic kidney disease (CKD), VOmax is potentially reduced by both central and peripheral factors. We aimed to investigate the effect on VOpeak of adding arm exercise to leg exercise.

Background: Sepsis and shock are common complications of necrotising soft tissue infections (NSTI). Sepsis encompasses different endotypes that are associated with specific immune responses. Hyperbaric oxygen (HBO) treatment activates the cells oxygen sensing mechanisms that are interlinked with inflammatory pathways.

Gold-based (Au) nanostructures are efficient catalysts for CO oxidation, hydrogen evolution (HER), and oxygen evolution (OER) reactions, but stabilizing them on graphene (Gr) is challenging due to weak affinity from delocalized [Formula: see text] carbon orbitals. This study investigates forming metal alloys to enhance stability and catalytic performance of Au-based nanocatalysts. Using ab initio density functional theory, we characterize [Formula: see text] sub-nanoclusters (M = Ni, Pd, Pt, Cu, and Ag) with atomicities [Formula: see text], both in gas-phase and supported on Gr.

Although alveolar hyperoxia exacerbates lung injury, clinical studies have failed to demonstrate the beneficial effects of lowering the fraction of inspired oxygen (FO) in patients with acute respiratory distress syndrome (ARDS). Atelectasis, which is commonly observed in ARDS, not only leads to hypoxemia but also contributes to lung injury through hypoxia-induced alveolar tissue inflammation. Therefore, it is possible that excessively low FO may enhance hypoxia-induced inflammation in atelectasis, and raising FO to an appropriate level may be a reasonable strategy for its mitigation.
