Functional profiling reveals altered metabolic activity in divers’ oral microbiota during commercial heliox saturation diving
Monnoyer, Roxane; Eftedal, Ingrid; Hjelde, Astrid; Deb, Sanjoy Kumar; Haugum, Kjersti; Lautridou, Jacky (Peer reviewed; Journal article, 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. In this study, ... -
Hemoglobin during and following a four-week commercial saturation dive to 200 meters
Luczynski, Damian; Lautridou, Jacky; Hjelde, Astrid; Monnoyer, Roxane; Eftedal, Ingrid (Journal article; Peer reviewed, 2019)Commercial saturation divers must acclimatize to hyperbaric hyperoxia in their work environment, and subsequently readjust to breathing normal air when their period in saturation is over. In this study, we measured hemoglobin ... -
Shifts in the oral microbiota during a four-week commercial saturation dive to 200 meters
Monnoyer, Roxane; Haugum, Kjersti; Lautridou, Jacky; Flatberg, Arnar; Hjelde, Astrid; Eftedal, Ingrid (Peer reviewed; Journal article, 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. In this study, ... -
Using Salivary Biomarkers for Stress Assessment in Offshore Saturation Diving: a Pilot Study
Monnoyer, Roxane; Lautridou, Jacky; Deb, Sanjoy Kumar; Hjelde, Astrid; Eftedal, Ingrid (Peer reviewed; Journal article, 2021)Health monitoring during offshore saturation diving is complicated due to restricted access to the divers, the desire to keep invasive procedures to a minimum, and limited opportunity for laboratory work onboard dive support ... -
What happens in the oral cavity of divers during commercial saturation diving? Environmental adaptations of the oral microbiota and effects on the divers’ physiology: analysis of the metagenome and salivary stress biomarkers.
Monnoyer, Roxane (Doctoral theses at NTNU;2022:84, Doctoral thesis, 2022)Commercial saturation diving has been used by the offshore oil and gas industry in the North Sea since the 1960s to perform long-term underwater work safely and efficiently. The highpressure oxygen conditions of the confined ...
