Effects of a preemptive alveolar recruitment strategy on arterial oxygenation during one-lung ventilation with different tidal volumes in patients with normal pulmonary function test [PDF]

open access: yesKorean Journal of Anesthesiology, 2014
BackgroundHypoxemia during one-lung ventilation (OLV) remains a major concern. The present study compared the effect of alveolar recruitment strategy (ARS) on arterial oxygenation during OLV at varying tidal volumes (Vt) with or without positive end ...

Oxygenation of adipose tissue: A human perspective

open access: yesActa Physiologica, 2019
Obesity is a complex disorder of excessive adiposity, and is associated with adverse health effects such as cardiometabolic complications, which are to a large extent attributable to dysfunctional white adipose tissue.

Uses and mechanisms of apnoeic oxygenation: a narrative review

open access: yesAnaesthesia, 2019
Apnoeic oxygenation refers to oxygenation in the absence of spontaneous respiration or mechanical ventilation. It has been described in humans for over half a century and has seen a resurgence in interest given its potential to delay oxygen desaturation ...

Pulse oximetry and oxygenation assessment in small animal practice [PDF]

open access: yes, 2016
Oxygen is essential for the cellular respiration of all aerobic organisms so it is important that the amount of oxygen present within the circulation can be measured.

Multiparametric Renal Magnetic Resonance Imaging: Validation, Interventions, and Alterations in Chronic Kidney Disease

open access: yesFrontiers in Physiology, 2017
Background: This paper outlines a multiparametric renal MRI acquisition and analysis protocol to allow non-invasive assessment of hemodynamics (renal artery blood flow and perfusion), oxygenation (BOLD T2*), and microstructure (diffusion, T1 mapping ...

Differences between umbilical blood gas in term and preterm newborns

open access: yesElectronic Physician, 2019
Introduction: Cord blood gas analysis reflects placental respiratory and metabolic function and is commonly used to assess fetal status at birth. Our aim was to identify the differences in blood gas parameters between the umbilical artery (UA) and ...
