High pressure excursion in a radial design oxygenator

open access: yesThe Journal of ExtraCorporeal Technology
Oxygenator high-pressure (HPE) is a phenomenon that can occur during cardiopulmonary bypass (CPB) in which the oxygenator inlet pressure increases rapidly, thereby limiting flow. Most perfusionists globally do not use inlet oxygenator pressure monitoring

Prediction of final infarct volume from native CT perfusion and treatment parameters using deep learning [PDF]

open access: yes, 2019
CT Perfusion (CTP) imaging has gained importance in the diagnosis of acute stroke. Conventional perfusion analysis performs a deconvolution of the measurements and thresholds the perfusion parameters to determine the tissue status.

Mild hyperthermia enhances sensitivity of gastric cancer cells to chemotherapy through reactive oxygen species–induced autophagic death

open access: yesTumor Biology, 2017
Mild hyperthermia enhances anti-cancer effects of chemotherapy, but the precise biochemical mechanisms involved are not clear. This study was carried out to investigate whether mild hyperthermia sensitizes gastric cancer cells to chemotherapy through ...

Indexed oxygen delivery during pediatric cardiopulmonary bypass is a modifiable risk factor for postoperative acute kidney injury

open access: yesThe Journal of ExtraCorporeal Technology, 2023
Background: Acute kidney injury after pediatric cardiac surgery is a common complication with few established modifiable risk factors. We sought to characterize whether indexed oxygen delivery during cardiopulmonary bypass was associated with ...

Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]

open access: yes, 2019
Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear.

Modeling lung perfusion abnormalities to explain early COVID-19 hypoxemia

open access: yesNature Communications, 2020
Early stages of the novel coronavirus disease (COVID-19) are associated with silent hypoxia and poor oxygenation despite relatively minor parenchymal involvement.

Effects of hyperoxia in pediatric perfusion patients: a scoping review

open access: yesThe Journal of ExtraCorporeal Technology
Hyperoxia in pediatric cardiopulmonary bypass patients is associated with adverse effects, including reoxygenation injury, increased mortality, heightened inflammatory response, and cerebral injury.

Usefulness of a visual aid in achieving optimal positioning for spinal anesthesia: a randomized trial

open access: yesBMC Anesthesiology, 2018
Background Optimal patient positioning is perceived as an essential factor to increase the success of performing neuraxial blockade. The primary objective of this study was to evaluate the benefit of using a visual image in addition to verbal ...

Modulation of Mitochondrial Bioenergetics in the Isolated Guinea Pig Beating Heart by Potassium and Lidocaine Cardioplegia: Implications for Cardioprotection [PDF]

open access: yes, 2009
Mitochondria are damaged by cardiac ischemia/reperfusion (I/R) injury but can contribute to cardioprotection. We tested if hyperkalemic cardioplegia (CP) and lidocaine (LID) differently modulate mitochondrial (m) bioenergetics and protect hearts against ...
