Shifts in the Oral Microbiota During a Four-Week Commercial Saturation Dive to 200 Meters

Frontiers in Physiology, 2021
During commercial saturation diving, divers live and work under hyperbaric and hyperoxic conditions. The myriads of bacteria that live in and on the human body must adjust to the resultant hyperbaric stress.

Variability of ventilation during exercise is greater in adolescents than in adults

Physiological Reports, Volume 14, Issue 7, April 2026.
Abstract Adolescence involves rapid physiological changes that may affect ventilatory control. This study used Poincaré and approximate entropy (ApEn) analyses to assess ventilatory variability and randomness during steady‐state exercise in adolescents and adults.

Heliox Improves Carbon Dioxide Removal during Lung Protective Mechanical Ventilation

Critical Care Research and Practice, 2014
Introduction. Helium is a noble gas with low density and increased carbon dioxide (CO2) diffusion capacity. This allows lower driving pressures in mechanical ventilation and increased CO2 diffusion.

Functional Profiling Reveals Altered Metabolic Activity in Divers’ Oral Microbiota During Commercial Heliox Saturation Diving

Frontiers in Physiology, 2021
Background: The extreme environment in saturation diving affects all life forms, including the bacteria that reside on human skin and mucosa. The oral cavity alone is home to hundreds of different bacteria.

Successful Management of Status Asthmaticus via Veno‐Venous ECMO: Extubation Prior to Decannulation—A Case Report

Case Reports in Critical Care, Volume 2026, Issue 1, 2026.
Background The use of veno‐venous extracorporeal membrane oxygenation (VV‐ECMO) has risen exponentially since the COVID pandemic. VV‐ECMO has been utilized successfully to manage patients in status asthmaticus who have failed to respond adequately to conventional therapeutic interventions and mechanical ventilatory support. However, clear guidelines on

Does heliox administered by low-flow nasal cannula improve respiratory distress in infants with respiratory syncytial virus acute bronchiolitis? A randomised controlled trial

Anales de Pediatría (English Edition), 2019
Objectives: The aim of our study is to evaluate whether the use of heliox (79:21) delivered through a low flow nasal cannula would improve respiratory distress in infants with acute bronchiolitis caused by RSV.

Central and Peripheral Mechanisms of Low Exercise Capacity in Prematurely Born Adults

Comprehensive Physiology, Volume 15, Issue 5, October 2025.
The lower exercise capacity described in preterm born adults is associated with impaired stroke volume augmentation in response to incremental exercise intensity, thus to a lower cardiac output response to exercise, compared to age‐matched individuals born at term.
