Changes in Muscle and Cerebral Deoxygenation and Perfusion during Repeated Sprints in Hypoxia to Exhaustion

open access: yesFrontiers in Physiology, 2017
During supramaximal exercise, exacerbated at exhaustion and in hypoxia, the circulatory system is challenged to facilitate oxygen delivery to working tissues through cerebral autoregulation which influences fatigue development and muscle performance. The

Active Preconditioning With Blood Flow Restriction or/and Systemic Hypoxic Exposure Does Not Improve Repeated Sprint Cycling Performance

open access: yesFrontiers in Physiology, 2019
PurposeThe aim of this study was to evaluate the effects of active preconditioning techniques using blood flow restriction or/and systemic hypoxic exposure on repeated sprint cycling performance and oxygenation responses.MethodsParticipants were 17 men ...

Early cases of acute infectious respiratory syndrome treated with photobiomodulation, diagnosis and intervention: Two case reports

open access: yesClinical Case Reports, 2021
PBMT using 630 + 660 nm wavelengths transcutaneously at 7 cm above chest area irradiating lungs and heart regions of patients with acute, infectious respiratory syndrome alleviated their respiratory symptoms, mitigated pulmonary inflammation and hypoxia.

The oxygen tightrope [PDF]

open access: yesCanadian Anaesthetists’ Society Journal, 1966
During anaesthesia and during the management of respiratory failure by intermittent positive pressure ventilation, incipient hypoxaemia is common owing to the frequent occurrence of an increased physiological shunt. This hypoxaemia may be offset by raising the inspired oxygen tension and by hyperventilation.

Uniform Oxygen Doping Leads to Superconductivity in FeTe Films [PDF]

open access: yesarXiv, 2013
FeTe is known to become a superconductor when doped with oxygen. Using layer by layer growth of single crystal films by molecular beam epitaxy (MBE), we have studied how oxygen incorporates. If oxygen is supplied during growth of a layer, it substitutes for tellurium inhomogeneously in oxygen domains that are not associated with superconductivity. When

Humidified rapid‐insufflation ventilatory exchange is a means of oxygenation during rigid bronchoscopy: A case series

open access: yesRespirology Case Reports, 2022
Humidified rapid‐insufflation ventilatory exchange (HRIVE) is an option for maintenance of oxygenation. This technique allows for oxygenation while the patient is apnoeic due to continuous positive airway pressure and gas exchange through flow‐dependent ...

From Experiments to Simulation: Shear-Induced Responses of Red Blood Cells to Different Oxygen Saturation Levels

open access: yesFrontiers in Physiology, 2020
Red blood cells (RBC) carry and deliver oxygen (O2) to peripheral tissues through different microcirculatory regions where they are exposed to various levels of shear stress (SS).

The Role of Hemodynamic Status and the Level of Oxygenation in the Development of Pressure Ulcer in Mechanically Ventilated Patients

open access: yesنشریه پرستاری ایران, 2013
Background and Aim: Despite of developments in healthcare systems and ongoing investments to prevent pressure ulcers, it still remains as a major problem particularly in critical care units .
